Abstract: A fluid flow valve is disclosed which includes a fluid flow assembly, a piston diaphragm assembly, and a reset plunger pin assembly. These three assemblies are configured to engage one another such that, when used in conjunction with a pressurized water source, they will split the pressurized water source into two portions, the one portion defining a main fluid flow pathway through the valve and, a much smaller proportion, defining a metered fluid flow pathway through the valve. The piston diaphragm assembly has a diaphragm or other equivalent structure for defining a metered fluid flow chamber, which metered fluid flow chamber is fluidly engaged to a pressurized water source through a metering channel in a piston. A reset plunger meter pin assembly engages the metered fluid flow or piston chamber of the piston diaphragm assembly and can initiate a timed flow of water or other fluid into the metered fluid flow chamber, which timed flow controls the flow of fluid or water flowing through the fill valve.

Abstract: Disclosed is a diaphragm valve. When a chamber is expanded by fluid supply into a pipe-shaped button, a valve stem is slightly moved upward by a rod and a shaft to open an outlet of an orifice. Fluid received in a space between a cap and a diaphragm and having a high pressure is discharged into an outlet-side space, whereby the diaphragm opens a guide conduit. When fluid is discharged from the pipe-shaped button, the diaphragm is moved toward the guide conduit, and the valve stem closes the outlet. The fluid in the inlet-side space has a high pressure, and the fluid in the space between the cap and diaphragm has a low pressure. The high pressure fluid flows toward the low pressure fluid through a pilot hole of the diaphragm. When fluid pressure balance is effected between the spaces, the diaphragm closes the guide conduit.

Abstract: A fluid diaphragm 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 diaphragm chamber is provided in the primary valve that is responsive to fluid pressure controlled by a pilot diaphragm valve. Upon release of fluid pressure in the pilot diaphragm 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 diaphragm in the primary valve allows repressurization and seating of the primary diaphragm, thus terminating fluid flow through the primary valve.

Abstract: A flush valve for use on toilet devices such as urinals and water closets includes a body having an inlet and an outlet. There is a valve seat in the body and a valve member movable within the body toward and away from the valve seat to control water flow between the inlet and the outlet. A housing is mounted on the valve body and there is a chamber within the housing. A piston is movable axially within the chamber and into the valve body for contact with the valve member to cause actuation thereof. There is a spring within the chamber which normally biases the piston outwardly from the valve body. A controlled passage in the housing connects the valve body inlet and the chamber to provide water under pressure to move the piston, against the spring, into the valve body to cause operation of the valve member. The improvement comprises a groove in the exterior of the piston, which groove is adjacent and faces a wall of the chamber.

Abstract: A replacement apparatus (50) for converting a manual flush mechanism to automatic operation includes a partition base (76) secured to a replacement cap (68) that forms two spaced-apart openings (96 and 98). A valve operator (58) is so mounted on the replacement cap (68) as to form with the upper surface of the replacement cap (68) a chamber (100) with which both of the openings (96 and 98) communicate. The partition base (76) separates a pilot chamber (26) from a relief chamber (94) that the partition base (76) and replacement cap (68) form. A replacement pilot valve member (102) controlled by the valve operator (58) in turn controls flow through the passage that comprises the openings (96 and 98) and the common chamber (100) with which they communicate. It thereby controls flow between the pilot chamber (26) and the relief chamber (94). The partition base (76) includes a wall (86 ) that is flexible so as to permit a main valve diaphragm (24) to flex.

Abstract: The valve for supplying a flow medium to a flow medium pipe which alternatingly carries different flow media, in particular to the flow medium pipe of a converter for treating the contents of a converter with various gaseous flow media, exhibits a chamber (20) between the flow medium inlet (7) and the flow medium outlet (10), which chamber may be closed on the side facing the flow medium inlet (7) by a piston (11) and on the side facing the flow medium outlet (10) by a disk (12). The piston (11), on the side turned away from the chamber (20), and the chamber (20) are optionally connectable via separate flow medium pipes (27 and 28, respectively) with the flow medium inlet (7) and the free atmosphere, respectively, to close the chamber (20) by the piston (11) and evacuate the chamber, or with the free atmosphere and the flow medium inlet (7), respectively, to open the chamber (20) by the piston (11).

Abstract: The invention relates to a hydraulic blocking valve, a so-called holding valve (10), the shutting-off member of which consists of a movable ball (16) coacting with a seat (17) in an inlet chamber (24). The space (15) on the side of the ball opposite its seat forms an operating chamber (15), and both chambers are joined by a constriction passage (13) counteracting flow of hydraulic liquid between the chambers. The operating chamber (15) is in communication with valve means (32) by the aid of which the pressure in the operating chamber can be heavily reduced, e.g. by being taken to a tank (44), resulting in that the ball (16) is thrust from its seat (17) to open the valve. A throttling means (25, 26) simultaneously comes into action for reducing the flow, i.e. liquid loss through the valve means (32) from the operating chamber (15). When the valve means is subsequently closed, pressure is once again built up against the ball so that the latter is pushed towards its seat (17) for closing the valve (10).

Abstract: A remote actuated metering valve system for supplying water to a washing fixture includes a main metering valve and at least one remote actuating relief valve connected to the main valve by tubing. The main metering valve has an inlet and an outlet with a valve seat between them and a movable piston which when the valve is in the normal closed position has its front face seated on the valve seat and its elongated nose projecting through the valve seat. The piston is maintained in the closed position by supply line pressure which is transferred via a bypass timing circuit to a pressure chamber behind the piston where it is sensed by the rear face of the piston. The pressure chamber of the main valve is connected by tubing to a normally closed remote push button relief valve. A second length of tubing leads from the relief valve to the supply source at a point downstream of the valve seat.
