Abstract: A method and a regulating valve for maintaining a fluid pressure within a defined volume (3), and simultaneous registering of discharge of fluid from the volume as a result of leakage or consumption. The fluid is supplied from a pressure regulating valve (20) provided with a means (5-7, 22-26) which opens for the supply of fluid to the volume (3) when the pressure therein has sunk below a first value (P1), and which shuts off the fluid supply when the pressure in the volume (3) has achieved a preset second value (P2) which is substantially higher than the first value (P1). Thus, after each opening of the regulating valve (20) there occurs a distinct pressure increase at the valve outlet. This pressure increase is registered as a pressure pulse, and the frequency of delivered pressure pulses is monitored and utilised as a measure of occurring leakage and/or consumption of the supplied fluid.

The valve is moveable relative to the housing in response to a change in pressure within the space between a first position which at least partially aligns the fluid transport member with each of the inlet and the outlet and a second position in which there is no alignment of the fluid transport member with at least one of the inlet and the outlet. A passage is provided in open communication with the space and one of the inlet, the outlet, and the transport member. Methods of using the pressure regulator are also provided.

Abstract: In a flow control valve, a spool is fitted into a cylindrical body including an input port and an output port. A spring is disposed between the spool and a flow rate setting plug at an end of the cylindrical body. A flow by-path communicating with the input port and the output port is provided on an outer peripheral portion of the cylindrical body. When a quantity of a fluid flowing through the flow control valve is reduced, the fluid flowing through the flow by-path compensates the reduction thereof. Accordingly, it is possible to maintain a constant flow rate.

A filter housing is mounted in the control chamber and mounts a filter and a valve seat that opens to the inlet passageway while spring urged mechanism moves the a valve stem to permit fluid flow through the valve seat and into the control chamber between the filter and diaphragm when the pressure therein falls below a preselected level, and then through the filter to the outlet passageway. When the pressure in the outlet passageway is at or above a preselected value, the pressure acts against a diaphragm whereby the piston retains the valve stem in a fluid flow blocking position.

Abstract: The current invention describes a pressure regulator for a gas burner that allows a consumer to make adjustments to the pressure regulator for differences in altitude as well as differences in the design and manufacturing tolerances of the pressure regulator from the manufacturer. Many traditional gas burners require a third party, with specialized equipment and training, to make corrective adjustments to the pressure to a gas burner after the burner is sold to the consumer. This pressure regulator incorporates a regulating curve into the pressure regulator, thus eliminating the need to remove the pressure regulator from the appliance and allowing the consumer himself to make the necessary adjustments to the burner without the assistance of a third party.

The piston assembly is responsive to pneumatic pressure flowing between the inlet and the outlet to reduce the biasing force acting on the valve member such that the valve member moves to its closed position when the outlet pressure exceeds a predetermined value.

Abstract: The precision regulator connects to a high pressure fluid source and regulates the pressure to a downstream apparatus. If an overpressure occurs, it can be vented to atmosphere. An elongate control stem engages a supply seal assembly and a vent seal assembly and moves axially and past these seal assemblies to achieve regulation and venting. The set point of the regulator can be adjusted by rotation of an adjustment knob that adjusts the position of the elongate control stem relative to the supply seal assembly and the vent seal assembly. Regulation is achieved primarily by use of a sensor piston which transfers fluid pressure from a regulated port to the sensor piston which is opposed by a spring. Both the supply seal assembly and the vent seal assembly rely upon an o-ring and a seal ring to achieve a seal with the outside circumference of the control stem. The o-ring is compressed and distorted, thus exerting forces against the seal ring to achieve a better seal.

Abstract: A safety valve has a valve body, a piston contained in the valve body, a soluble alloy filled between said piston and said valve body, and a spring inserted between the piston and the valve body. The piston includes a path connecting both ends thereof, and has a first gas pressure receiving surface and a second gas pressure receiving surface at both ends. The first and second gas pressure receiving surfaces have the same area; the piston works as a balanced piston where the gas pressure in the fuel tank functions in reverse directions. As a result, no gas pressure is applied to the soluble alloy but only the energizing force of the spring is applied. Therefore, the pressure applied to the soluble alloy can be kept constant without regard to the increase of the gas pressure.

Abstract: When a valve body of a pressure-reducing valve is displaced in the direction indicated by the arrow B, a seal pad of a valve seal mechanism on the valve body abuts against a ridge on a seat, which enters the seal pad to provide a seal therebetween. When the ridge enters the seal pad by a distance, abutment surfaces of holders on the seat are held against the seal pad, preventing the ridge from entering the seal pad beyond the distance. The distance by which the ridge enters the seal pad is thus made constant. The ridge is spaced from the abutment surfaces by a groove, which communicates with a primary port through grooves between the holders, keeping a constant valve sealing area. The pressure-reducing valve which incorporates the valve seal mechanism has a constant quality level.
