Description
"MIXING VALVE: FOR ~IOT AND COLD WATÆR
SPECIFICATION
The present invention relates to mixing valves for hot and cold water in general and in particular to an improved mixing valve for hot and cold water comprising, inside a cartridge type body, two valve means represented by two overlapping disks, made, ~or instance, of a ceramic material, with s~parate inlets for hot and cold water and one outlet for the mixed water, one of said dislcs being fixed to the cartridge type body, while the other one is movable and positionable on top of the fixed disk by means of a control lever capable to osci:Llate on a trans-versal axis and to turn around a vertical axis.
Usually the oscillation of the control lever causes the opening and closing of the valve means to let out the water or stop it, while the rotation of said lever in one sense or ~he other is designed to set the angular position of the movable disk on -the fixed one in order to let out either cold or hot water or to mix the two water types at differ~nt ratios-The problem still to be solved as far as this kind o~ mixing valves are concerned, is the possi-bility to adjust the maximum water outpu-t and to sultably limit the temperature of the mixed water when the valve has been fully opened. Such a possi-bility appears desirable for a more efficisnt use Qf mixing valves by preven-ting an unnececessary waste of water and in particular of hot water in order to achieve a substantial saving of energy.
It is therefore the scope of the present in-vention to solve said problem by associating to the mixing valve some simple and economical means allow-ing to vary and adjust the maximum oscillations of its control lever in order to adjust the water out-put, as well as to limit the rotation of the same lever at least in one direction so as to adjust the hot water output and thus the maximum tempera-ture o~
the mixed water, the temperature of the available cold and hot water being known.

The volume rate of flow limiting means i.nclude a slide gate posi-tioned on the setting ring, the slide gate including an opening, the control lever passing through the opening of the slide gate, a cross member connected to the slide gate, the slide gate and the cross member being displaceable with respect to the slide ring and the control lever, the slide gate including a slot, a screw positioned in the slot and fixable relative to the se-tting ring for fixing the slide gate and the cross member relative to t~le setting ring to limit the movement of the control lever about the transverse axis.
The valve offers the advantage - 2a -n ~ ,r~
that it can be di~ectly adjusted even by the plumber and without using any special tools1 simply basing on the flow and temperature of the available hot and cold water~
More details of the invention will however be apparent from the description given hereinafter with reference to the figures of the accompanying drawing in which:
Figure 1 is a schematical and partly sectional view oE a mixing valve fitted inside a tap;
Figure 2 is a partial section of the cartridge and of the means to adjust the output and tempera-ture of the water cooperating with the control lever; and Figure 3 is a section on the line III-III of Fig. 2, In said drawing Figure 1 shows the cartridge type body (10~ of the valve ~ixed by means of a clamping ring t11) into the body of tap (12) enclos-ing pipes (13, l4) for the separate inlet of hot and cold water and a spout (15) ~or the outlet of the water to be used.
Inside the cartridge type body the valve el-ements are mounted, said elemen-ts being in particu ~ (3~
lar two overlapping disks of cermaic or other suit-able material, the bottom disk (16) being fixed while the top disk (17~ can be displaced on the fixed one by means of a control lever (18), the section of which may be square or differently shaped, said lever being fitted wi~h a handle (19).
The fixed disk (16) has two (not represented) openings respectively connected with cold and hot ! ~ water conduits (13, 14) and one opening (20) to let out the cold, hot or mixed water through spout (15) of the tap. The movable disk (17) has in turn a mix-ing chamber (21) to be placed into different posi-tions towards the openings in the fixed disk in order to control the outflow of the water.
The cartridge type body (10) has a neck (10') on its top and the control lever (18) is assembled, as usual, on a horizontal pin (22) transversally fixed in a supporting bush (23) rotating inside neck (10') of body (10). The control lever (18) may thus swing on the horizontal pin (22) and rotate around a vertical axis (X) coincident with the rotational axis of the supporting bush (23). The swinging of the control lever (18) causes the opening and clos-ing of the mixing valve by displacing the movable disk (17) on the fixed disk (16) while by turning u~
said control lever on its axis (X) the type of water to be delivered by the tap is selected amony cold, warm and rnixed water as required.
According to the invention, on the neck (10~) of the car-tridge type body (10~ a stationary bush (25) and a setting ring (26) rotating on axis (X) together with the control lever (18) are mounted.
Bush (25) is fitted with a bottom flange (25') fastened on the cartridge type body (10) by means of a clamping ring (11 ) presenting at least one peripheral to-oth (27) to engage a corresponding notch (27') on said body (iO) in order to preven-t said bush (25) from rotating. In addition, said bush (25) also presents a recess ~28) delimiting ~wo shoulders (29,30) having the purpose to limit the rotation of control lever (18) by means of setting ring (26) and in particular by means of a stop screw (31) is fixed in an arc shaped slot ~32) recessed into setting ring (26) and cooperating with shoul-ders (29, 30) in order to limit the rotation of the lever (18) at least in one sense to vary, for in-stance, the flow of hot water to be mixed with the cold water and thus adjust the temperature of the water delivered by the tap. Of course, by suitably changing the position of screw (31) along slo-t (32) .
it is possible to change at will the temperature of the mixed water delivered when the valve is all open.
The setting ring t26) also presents a hole (33) for a screw ~34) to fix a slide gate (35) wi~h an opening (36) shaped according to the section o~
the control lever (18). A slot (35') in slide gate (35) cooperating with said screw (34) allows to displace said slide gate along the diameter of ring (26), while its cross member (37) opposite to slot (35') is cooperating with stop face (18') of control lever (18) when it is moving on pin (22) towards its opening position. Owing to the possibility to posi-tion slide gate (35) its cross member (37) can be approached to or moved away from the control lever (18) in order to adjust its oscillation before it contacts cross member (37). Analogously, the maximum opening of the mixing valve can be adjusted in order to control the quantity of water delivered when the valve is all open.
Finally it is pointed out that both the sett-lng ring (26) and the slide gate (35) can be coupled to scales or any other means showing the flow rate and temperature of the water to be deliverd once the mixing valve has been fully opened.
