Definitions
- the present invention relates to the attachment of a supply conduit to the inlet of a valve and particularly relates to solenoid operated valves employed for controlling the flow of water where the body or main structure of the valve is formed of non-metallic material to provide electrical isolation of the solenoid from the conduit to protect the user from the hazards of electrical shock.
- Solenoid operated valves are commonly employed in household appliances such as, for example, clothes washing machines, dishwashers and ice makers for refrigerators. Appliance water valves of this type are therefore typically connected to a household power supply either 240 Volt or 117 Volts AC which is a high enough voltage to create a hazardous condition for the appliance user in the event of contact occurs with the electrical solenoid operator and the water supply.
- typical appliance water inlet valves have the body thereof molded from plastic material and the coil typically encapsulated with plastic material for reducing the likelihood of occurrence of electrical shock.
- Appliance water inlet valves are, in many installations, connected to a flexible conduit by either a threaded hose-type connection or by compression type tubing connection in the case of small diameter bendable or deformable metal tubing as the supply conduit.
- the present invention provides a technique for connecting a flexible metal conduit to the inlet of a solenoid operated water valve of the type having a non-metallic body in a manner which permits the conduit to be inserted in the inlet and secured and sealed therein without the aid of separate fittings, fasteners or tools.
- the water valve conduit connection of the present invention is characterized as a non-removable quick-connect.
- the conduit connection of the present invention is particularly suitable for connecting bendable or deformable metal conduit to the inlet of a solenoid operated water valve employed in a refrigerator ice maker where it is desired to connect a supply conduit to the water valve at installation of the ice maker during manufacture of the refrigerator with the portion of the conduit extending externally of the refrigerator cabinet and adapted for user connection thereto externally of the refrigerator.
- the quick-connect method of the present invention permits the connection of a tubular flexible metal conduit to the water valve inlet without the need of compression fittings, threaded connections or any tools.
- the installer need only manually insert the end of the tubing into the valve aperture in the valve inlet and push the tubing sufficiently inward to engage a pair of seal rings and subsequentially frictionally engage a spring member to retain the conduit sealed into the valve inlet in a non-removable manner.
- FIG. 1 is a cross sectional view of a non-metallic valve with a metal conduit quick- converted to the inlet according to the present invention
- FIG. 2 is an enlarged view of a portion of FIG. 1.
- a valve assembly indicated generally at 10 has a molded plastic valve body 12 having an inlet end portion 14 and an outlet 16 with an outlet passage 18 having a valve seat 20 formed therein and an inlet passage 22 communicating with a valving chamber 24.
- Valving chamber 24 is closed by a guide member 26 secired to body 12 and which has slidably received therein a ferromagnetic armature 28.
- the guide member 26 is surrounded by axially spaced tubular pole pieces 30, 32 which are surrounded by a coil 34 encapsulated with suitable plastic material 36 and having at least one electrical connector terminal 38 extending therefrom.
- the armature 28 has a valving surface 40 thereon for contacting valve seat 20 to block flow from inlet passage 22 to the outlet passage 18.
- the electromagnetic field created by current flow in coil 34 effects lifting of the armature 28 and valving surface 40 from valve seat 20 thereby permitting flow from inlet passage 22 to the outlet passage 18.
- the inlet end portion 14 of the body 12 includes a chamber 42 which communicates with inlet passage 22 and which chamber has received therein a flow control washer 44 and retaining capsule 46 therefor.
- the chamber 42 also includes a generally cup-shaped filter screen 48.
- chamber 42 in the inlet portion 14 of the valve body 12 is closed by a cap member 50 which has an annular groove 52 formed therein which is received over a tapered annular rib 54 formed on the rim of the inlet portion 14 of the valve body and secured thereto by weldment, as for example friction welding by spinning or by ultrasonic welding.
- the closure cap 50 has a bore 56 received therethrough which is sized and configured to have slidably received therein one end of a flexible tubular metal supply conduit 58.
- the interior face of closure 50 has formed therein a counterbore 60 which has received therein a pair of resilient seals in the form of O-rings 62, 64 which are radially compressed upon insertion of the tube 58 in bore 56.
- a second counterbore of a larger diameter and denoted by reference numeral 66 is formed in the face of closure 50 and has received therein a deflectable metal spring member 68 which may have an annular configuration and may have a plurality of radially inwardly extending fingers formed thereon.
- Spring member 68 is retained in the counterbore 66 by a backing member or washer 70 which is secured by deformation of the material of closure 50 as, for example, the annular rib 72 formed about counterbore 66. Rib 72 is deformed from the position shown in dashed outline to the position shown in solid outline in FIG. 2.
- the present invention thus provides a unique method for quick-connecting a tubular metal conduit to the inlet of a valve and particularly an electrically operated valve having a non-metallic body without the aid of separate fittings, fasteners or tools in a manner which is simple and low in cost.
- the quick-connect of the present invention is intended for installations where the conduit is not removable after connection to the valve inlet.
- the non-removable quick-connect of the present invention is particularly suitable for electrically operated appliance water inlet valves such as those employed in a refrigerator ice maker application.
