Abstract: A simplified service connection valve assembly that provides access to fluid systems, such as air conditioning units, freezer units, refrigeration units and like systems, for fluid processing through the valve assembly. The valve assembly can include a valve body and a valve core received in the valve body.

Releasing the interlock between the two valve housings displaces the two raised bosses to allow the respective reed valves to close prior to separating the two valve housing.

Abstract: Various types of valves are disclosed, as well as the use of the same in a reaction control system for space travel vehicle applications. Multiple functions are provided by one of these valve designs by providing multiple flowpaths through the valve. An inflow and outflow tube of this multifunctional valve are fluidly interconnected with first and second chambers, respectively, within the valve. These first and second chambers are isolated from each other by a barrier assembly which may be “removed” at the desired type by a barrier rupture assembly to provide one of the noted multiple flowpaths (i.e., the inflow tube, the first chamber, the second chamber, and the outflow tube). A separate service port is fluidly interconnected with each of the first and second chambers, and a separate service valve may be disposed in each of these service ports to provide additional flowpaths for the multifunctional valve.

This invention can be incorporated with electric exhaust (intake) fan for rapid injection and release of air. In particular, the present invention is the first device of which the air valve can be opened and closed by winding, thereby ensures the correct motion. When it is switched to the release position, the air inside the mattress will be released rapidly to facilitate the execution of CPR. The additional function of automatic pressure release makes this device a practical and innovating one.

A sealing member forms part of the second threaded bolt portion whereby on full insertion of the second threaded bolt portion in a first position within the first threaded bolt portion, the sealing member engages an adjacent surface to prevent the escape of fluid from the container and, on retraction to a second position, the flow of fluid through the first and second threaded bolt portions is permitted.

Abstract: Automatic swimming pool cleaning systems are disclosed. The systems include an automatic swimming pool cleaner incorporating one or more curved wipers protruding from its lower surface. The wipers and flat bottom of the cleaner induce a vortex as fluid flows to its central inlet, entraining debris in the flow. A fluted throat surrounding the inlet additionally assists the interior of the base of the cleaner in retaining debris when opened for cleaning, additionally providing an improved flow path for enhanced debris pick-up.Also disclosed is a valve useful for controlling and indicating the rate of fluid flow to a cleaner. Included within the valve is a plunger attached to a spring, with the spring force opposing fluid flow through the valve. Flow sufficient to overcome the spring force compresses the spring, however, thereby moving the plunger within the tube and providing a dynamic indication of the rate of fluid flow.

Two semicylindrical cotters are pushed by a press member, so that the valve is driven and reciprocated. When the valve is moved upward or downward to open a port of a valve casing in which the valve is contained, fluid flows, thereby allowing fluid pressure to act on the fins, so that valve rotates little by little around its axis owing to a slight gap between the cotters and the valve stem.

Abstract: A valve comprises upper and lower sections which are rotatable relative to one another about a longitudinal axis. Relative rotation in one direction causes the valve to open, and relative rotation in the opposite direction causes the valve to close. Opening and closing of the valve is caused by a camming arrangement between the two valve sections. One of the valve sections includes an outer skirt which is cammed outwardly as the valve sections are axially forced together during assembly, to enable the cam elements to snap together. Each valve section is of one piece plastic molded construction.

Abstract: Disclosed is an improved ball valve structure and a well safety valve utilizing the improved ball valve. The improved valve includes a metal seat member having a resilient section and control arms, which may be positioned to initially sealingly engage the seat with the ball and to compress the seat resilient section to control the force sealingly engaging the seat with the metal ball and thereby limit frictional forces opposing opening rotational forces when pushing on the seat to open the valve. The control arms are positioned by rings threaded on the seat above the control arms and below a shoulder in each arm. When the seat is moved down to open the ball valve, opening rotational forces are imparted to the valve ball through both the seat and control arms. The well safety valve utilizing the improved ball valve structure includes an annular metal valve and means increasing the force sealingly engaging the seat with the valve ball as pressure below the closed ball valve increases.
