Abstract: A fluid diaphram valve and interconnected pilot valve apparatus for control flow of fluid discharge from a pressurized fluid distribution system. The apparatus has a primary valve with an inlet adapted to receive fluid under pressure, and an outlet adapted to discharge fluid to an outlet conduit. A diaphram chamber is provided in the primary valve which is responsive to fluid pressure controlled by a pilot diaphram valve. Upon release of fluid pressure in the pilot diaphram valve, the primary valve allows passage of fluid to the outlet conduit. Bleed fluid from the pilot valve is also discharged into the outlet conduit and is thus saved for use. Upon closure of the pilot valve, a bleed port in the primary diaphram in the primary valve allows repressurization and seating of the primary diaphram, thus terminating fluid flow through the primary valve. A novel, retrograde motion actuator is also described for use in manual operation of the pilot valve from a fixed location such as cabinets below kitchen sinks.

Abstract: A valve assembly for a faucet is operated by an actuation lever(s) normally positioned to be engaged by a container, for example, into which water is to be discharged from the faucet. For normal operation the lever(s) is moved in a self-return range of about 10 to 50 degrees. The lever(s) can also be swung further to a fully-on position so that the faucet can function in the normal manner by its valve system. The lever(s) operate a cam which acts on a cam follower presented by a valve stem. Responsive axial movement of the valve stem in opposition to spring pressure opens a valve.
