Abstract: Disclosed is a proportioning valve which is of simple design compared to prior art arrangements and is easily constructed. The valve comprises lower and upper body members, the lower body member having a chamber region closed off by a flexible diaphragm of elastomeric material or, in an alternative arrangement, two diaphragms. The bottom of the chamber region has first and second inlets and the wall of the chamber has at least one outlet. Two cam followers are secured above the diaphragm, for axial movement only, in alignment with the inlets and they co-operate with a face cam which is movable both axially and rotationally. Rotation of the face cam results in one cam follower moving up, while the other moves down, thus resulting in movement of one portion of the diaphragm towards its associated inlet while the other moves away from its associated inlet, thereby controlling the relative rates of flow of liquid into the chamber region from the inlets.

Abstract: Disclosed is a filter for use in a faucet of the type having a removable cartridge member receivable in an underbody member, the cartridge member carrying a cam member, at least one cam follower member and a valve member actuated by the cam follower member upon movement of the cam to control fluid communication between a spout and a source of water. The filter member is removably attached to a projection on the valve member and moves with it within a passage in the underbody member through which water flows from the source. By this means, large particles are prevented by the filter from entering the faucet. The filter comprises an inner annular member, an outer annular ring member, and a plurality of flat web connecting members extending radially between the inner and outer annular members. The inner annular member has a through hole which tapers from a first diameter to a second diameter so that the inner annular member can be forced over a head portion on the projection whereafter it is latched thereon.
