Abstract
ABSTRACT OF THE DISCLOSURE
The invention relates to a single-grip valve having a valve body with water inlets and a water discharge outlet and ceramic discs fitted in the body, the mutual position of the discs determining the mixing ratio of cold and hot water. One ceramic disc is moved by a lever which is attached with bearings to a turning piece fitted to turn inside the body. In order to limit the turning movement of this turning piece and, together with it, that of the lever, one of the members, the turning part and the body part surrounding it, is equipped with axial protrusions spaced around it and the other has respectively at least one axial protrusion. However, the protrusions of the different members do not overlap each other in the radial direction, but between the said members there is fitted at least one detachable limiting piece which can engage between the protrusions of one member and radially overlaps the protrusions of the other member.

Sinyle-grip mixing valve The present invention relates to a single-grip mixing valve, which has a valve body with water inlets and a water discharge outlet, ceramic discs fitted in the body, the mutual position of the discs determining the mixing ratio of cold and hot water, and a lever for moving one of the ceramic discs, the lever being attached with bearings to a turning piece fitted to turn inside the body, the said turning piece and the body part surrounding it being equipped w:ith protrusions directed towards each other in order to limit the turning movement of the turning piece and, together with it, that of the lever.
An arrangement like this for limiting the movement of the lever of a mixing valve is known previously on the basis of, for example, German utility model no. 77 27 623, published May 31, 1979, in the name of Friedrich Grohe Armaturen-Fabrik GMBH et Co, FRG. In it the lever is attached with bearings to a sleeve which has inside toothing and fits over a hexagonal piece attached to the body The sleeve can be positioned at different angles in order to alter the control range of the mixing ratio.
The limitation of the movement of the lever is achieved by means of a notch in the sleeve, the lever extending through the notch and the sides of the notch serving as limiters for the lever.
Thus the "width" of the control range is always the same and the range can be shifted only more towards "hot" or "cold".
German Lay-Open Print no. 1,258,688, published January 11th, 1968, in the name of Standard Screw Company, also discloses a single-grip mixing valve of the type mentioned in the ingress, in which the control range is limited by inwards directed protrusions in the surrounding body and outwards directed protrusions in the turning part, one of the protrusions consisting of the head of a screw and the other one of a protrusion in a sleeve attachable in different positions by means of the screw. Thus, even in this arrangement, the control range - lA -

Thus, even in this arrangement, the control range - lA -
- 2 -can be extended or reduced as regards one of the extreme positions~ The disadvantage is that the possibilities for varying the control range continue to be limited and, above all, that when the screw attachment slackens the sleeve can turn and the control range can change. A preselected, fixed, precise mixing position is not possible in this arrangement.
The object of the present invention is to provide - 10 a structure which is improved in this regard but still equally simple and makes it possible to select the control range practically arbitrarily and also to fix the mixing ratio at that desired.
A contruction in accordance with the present invention comprises a single grip mixing valve having a first part comprising a valve body with inlets for hot and cold water and an outlet for mix water in the body.
Ceramic discs are fitted inside the body and have openings therein cooperating with the inlets and outlets in the body and with each other in order to regulate the mixing ratio of cold and hot water.
A second part comprising a turning piece fitted for limited turning movement is provided inside the body.
A lever is attached with bearings to the turning piece and engages one of the discs in order to move the same. Axial protrusions are provided in the turning piece and in the surrounding body respectively, there being at least one protrusion in one of the parts and several protrusions in the other part, respectively, the protrusions facing each other radially in a non-overlapping manner. At least one overlapping limiting piece is inserted between the ~ 2A ~
parts and engages the protrusions of the one part while radially overlapping the protrusions of the other part in order -to provide a selectable limit for the turning movement of the turning piece and, hence, of the lever.
The invention and its other characteristics and advantages are described below in greater detail in the form of an example and with reference to the accompanying drawings, in which Figure 1 depicts a side view of a valve according to the invention, partly as a section, and Figure 2 depicts a section along line A-A in Figure 1 In the drawings, the body of the mixing valve is indicated by reference numeral 1. It includes an upper part la, which has been joined to the lower part of the body by, for example, ultrasonic welding.
Furthermore, the body has two inlets 2 for cold and hot water, and one discharge outlet 3 for mixed water.
The mix~ng ratio of cold and hot water is adjusted by a method known ~er se by means of two ceramic discs 4 and 5, of which disc 4 is fixed to the body and disc 5 is movable.
A plastic piece 6 is fixed to disc 5, and together with the disc the piece 6 forms the water mixing chamber and is movable by means of a manual lever 7, which engages a :
slot in the upper surface of the piece 6.
Both the structure and operation of all the parts described above are well known to an expert in the art, and therefore they are not described in greater detail in this context.
We can refer to, for example, Finnish Patent 58823, published December 31, 1980, in the name of K. Oras Oy.
In the upper part la of the body there is fitted a sleeve-like piece 8, which can turn in the said upper part and to which lever 7 is further attached by means of a shaft 10.
The piece 8 is held in place by a locking ring 9.
The turning movement of the lever around the shaft 10 is limited by the side walls of the central opening in the sleeve piece 8, the walls coming into contact with the lever arm.
The turning movement of the lever, or the sleeve 8, in relation to the body is limited in accordance with the invention as follows. The external surface of the sleeve 8 is provided with axial teeth 11, which are best seen in the cross section in Figure 2. The body part la has respectively two shoul.ders 12, which are situated diametrically opposite each other. The protrusions of the sleeve and the body part, in other words, the teeth 11 and the shoulders 12, do not, however, directly engage each other, but between the sleeve and the body there are fitted two axial pieces 13, which engage the teeth 11 and which, when the sleeve is turned, are stopped by the shoulders 12, thereby limiting the t.urning movement of the lever 7. The freely placeable limiting pieces 13 have an advantage in that the extreme 7~
positions of the lever can be selected arbitrarily in a very simple manner only by altering the position of the pieces 13. The width of a piece 13 in the case depicted in the figures is the same as the wi.dth of the shoulder 12, and this further corresponds to the pitch of the tee-th 11, as shown in the figures. Thus the limi.ting pieces 13 can be placed, for example, on both sides of the shoulder 12, in which case a fixed mixing ratio can be obtained, when so desired. The essential idea is, however, as stated above, that an arbitrary selection of both extreme positions of the mixing range is possible~
By turning the limiting pieces 13, their contact surface can be caused to be aligned with either side of a tooth, in which case in the presented example the pitch of the arrangement is 15.
The notches between the teeth 11 chn widen somewhat inwards, so that the pieces 13 remain better in contact with them.
