Abstract: An air compressor includes a cylinder housing having an outlet tube, a piston slidably received in the cylinder housing and having a piston rod and a bore, and a motor coupled to the piston for moving the piston relative to the cylinder housing in a reciprocating action, in order to generate pressurized air. A valve device includes one side secured to the piston, an inner peripheral slot formed between two blade members, and two coupling members coupling the two ends or two sides of the blade members together for increasing a resilience of the blade members and for preventing the valve device from being bent or distorted or deformed when the piston is moved in a very high speed relative to the cylinder housing.

Abstract: A filling system for a toilet tank prevents continual flow to the tank in the event of a leak from the tank by providing a hydraulically actuated safety valve for halting water flow to the filling valve in the event that the water flow continues for a time longer than an expected time of filling. The safety valve has a valve member connected to a piston mounted in a cylinder defining a first chamber on one side of the piston and a second chamber on the other side. A venturi in the supply duct provides in a low pressure chamber of the venturi a water pressure lower than the supply pipe pressure such that a pressure difference across the piston caused by the difference in pressure between the supply pressure and the low pressure chamber causes the piston to move from the first end toward the second end. A flow control orifice regulates a rate of flow of water such that a time of movement of the piston is greater than an expected time required to fill the toilet tank.

Abstract: A mechanical automatic fluid consumption limiting apparatus for limiting flow through a primary flow line includes an actuating line, a control line, a rotary meter, a control assembly, an actuating valve, a diaphragm valve on the primary line, an eductor and an engagement controller. The actuating valve, initially spring-biased to a non-actuating position, is rotated to an actuating position effecting closure of the diaphragm valve responsive to a predetermined quantity of flow through the rotary meter and mechanical response of the control assembly. An eductor diaphragm is positioned within the eductor responsive to flow through the primary line and pressure from the actuating line. The engagement controller is connected to the eductor diaphragm. The control line by-passes the diaphragm valve to provide pressure within the eductor to re-position the eductor diaphragm after closure of the diaphragm valve.

Abstract: A safety device protects a mud pump from an over pressure condition, which can occur during normal operation. The mud pump discharge couples to a high pressure inlet at the bottom of a valve body and the discharge outlet from the valve discharges to the side of the body, ninety degrees to the inlet. In a first aspect, the safety device includes a load piston mounted to a shaft which passes through a pressure chamber cap and connects to a pneumatic cylinder assembly on the top side of the pressure chamber cap. The pneumatic cylinder assembly is operated by a control valve mounted to the base of the cylinder to set the pressure at which the safety device actuates. In a further aspect, the safety device includes a light transmissive indicator cylinder, with a flag therein mounted on a rod coupling the valve to a pneumatic actuator piston, between the actuator piston and the valve.

Abstract: A self-closing valve assembly has a main valve having a seat between a high-pressure input conduit and a low-pressure output conduit, a main valve element movable into and out of engagement with the seat to block and permit flow from the input conduit to the output conduit, and a chamber behind the main valve element pressurizable to press the main valve element against the seat. A small-diameter passage extends from the input conduit to the chamber so that the chamber can be pressurized via the passage from the input conduit to hold the valve element against the seat. A pilot or control valve connected between the chamber and the output conduit can be opened to depressurize the chamber and thereby lift the valve element off the seat.

Abstract: A self-closing water valve has a valve seat, a valve closing member cooperates with the valve seat so as to abut against and to be lifted from the valve seat, and an auxiliary valve coupled with the valve closing member for reducing operational forces during lifting of the valve closing member from the valve seat and therefore opening the valve.

Abstract: A self-closing valve fitting comprises a housing which bounds an internal space and includes a water inlet and a water outlet communicating with the internal space and a valve seat situated between the water inlet and the water outlet. A valve piston is received in the internal space for movement toward and away from the valve seat and for attendant cooperation with the valve seat. The valve piston delimits in the internal space, at a side thereof which faces away from the valve seat, a relief chamber. An actuation valve is arranged in the valve piston between the relief chamber and the water outlet and forms a part of an arrangement for self-retention of the fitting during a delayed opening movement of the valve piston. A deaeration member is arranged in the relief chamber and forms at a region of a jacket wall of the housing which circumferentially bounds the relief chamber at least one small flow-through passage which leads to the actuation valve.

Abstract: A flushometer valve integrable with a structure to which it is mounted.

Abstract: A self closing valve has a housing with a water inlet and outlet and with a valve piston positioned inside it in such a way that the end of the piston facing away from the valve seat demarcates a discharge chamber in conjunction with the inlet and outlet through flowthrough passages that are activated in opposite directions by supplementary-valve controls in such a way that the duration of operation is determined by a decelerated opening stroke of the valve piston and closure is activated by a rapid closing stroke of the valve piston. The initiating position of the supplementary-valve controls that is provided during the opening activation of the valve piston is designed to maintain itself hydraulically as the result of a pressure difference generated at a choking device as the result of the flow through the valve and discontinuing the automatic maintenance shifts the supplementary-valve controls.

Abstract: An improved automatic shut-off valve that allows the temperature of discharged water to be adjusted by rotating the valve operating handle. The means for shutting off the discharge of water is simplified by attaching a valve closure member directly to a piston which is pushed downward manually to initiate flow and then forced upward by a spring to seat the valve closure member and stop the water flow. The piston moves axially inside a piston cylinder that has a hole in its bottom, and a pin connected to the piston sits in the hole. The clearance between the hole and pin determines the rate at which water can flow into the cylinder, thereby controlling the rate at which the piston is returned to its normally shut position by the spring.
