Abstract: The present invention provides a water control valve with snapping action. The valve shell of the water control valve includes a main body and combined base. A snapping assembly is arranged between the main body and combined base, being in snap-fit engagement, so that the inner space of the valve shell expands to accommodate more switching valve assemblies for better applicability. When the main body is coupled with the combined base, the overlapped portion of the main body and combined base can be reduced by configuration of the snapping assembly, thereby optimizing the utilization of the inner space. So, the switching valve assemblies of different dimensions and specifications are suitable for a wider range of applications.

Abstract: Male and/or female members of a hydraulic coupling have an internal poppet valve that is held in the closed position by a flat wire, helical compression spring. The spring is configured such that when the poppet valve is moved to its fully open position, the coils of the spring are completely compressed thereby forming a substantially smooth bore tube for the flow of hydraulic fluid. The flat wire, helical compression spring may also act as a valve stop, limiting movement of the poppet valve and providing the necessary resistance to move the valve actuator of a corresponding valve in a mating member.

Abstract: The present invention presents various novel approaches to solving the problems inherent in measuring biological pressures in high pressure systems. Thus, to protect a pressure transducer exposed to fluid flows at higher pressures than its overpressure rating, a novel valve is used that closes a protected leg in which the transducer is located. The various exemplary embodiments of such valves each have a high pressure input, one or more low pressure inputs, and an output. In operation, when a high pressure fluid flow occurs at a high pressure input, such valves automatically close the low pressure inputs. Alternatively, a novel transducer system is presented, which automatically limits the effective pressure sensed by a transducer to a certain maximum.

Abstract: Water leak detection and prevention systems and methods in which water is only delivered to the water pipes in the building when a faucet or appliance demands water and water is delivered through a normally closed shut off water valve. During the period that the main water is shut off, the water pressure in the water pipes is continuously monitored to detect a water leak in the building. Detection of a leak causes an alarm to be sounded and a continued closure of the shut off valve.
