Abstract: A regulator valve has an anti-seize feature when in the hard stop position. The valve is providing with a biasing force away from the hard stop position when in the hard stop position sufficient to prevent seizure of the drive screw in the hard stop position. This biasing force may be provided by a resilient member and/or a plastic, instead of a metal, adjusting screw which may provide sufficient resiliency to prevent seizing in the hard stop position. A resilient member could be a washer such as a spring washer, a wave washer, or even a compressible flat.

The coupling member allows one of tilt and eccentricity of an axis of the spool relative to an axis of the linear-motion member.

Abstract: A rough-in assembly for mounting a free-standing faucet on a floor is revealed. The rough-in assembly includes a mounting base, a connection tube set having cold-water and hot-water connection tubes, a fixing plate, and a plurality of nuts. The mounting base consists of a bottom plate fixed on a laminated wood, a tube-fixing portion positioned on the bottom plate and provided with two locking slots, and a plurality of bolts projecting from the bottom plate and inserted through a mounting hole on the floor. The cold-water and hot-water connection tubes are locked in the two locking slots of the tube-fixing portion. The fixing plate allows the bolts of the mounting base to pass therethrough. The nuts are threaded on the bolts for fastening the fixing plate on the floor. Thereby the free-standing faucet is secured on the floor firmly and production cost is dramatically reduced.

Abstract: A system and method for an automotive transmission includes one or more restrictor devices that are installed within a valve body of the automotive transmission to improve performance by establishing a flow limit along the compensator circuit. The complex fluid circuits of certain automotive transmissions having eight to ten speeds allow line pressure supply to bleed out during certain critical functions, such as low rotations per minute hot engagements, which can severely damage the transmission. By limiting flow, the line pressure supply can be preserved to prevent the compensator circuit from bleeding out in these critical functions. The instant invention limits flow by replacing the standard compensator valve with a compensator valve that has a larger spool diameter. Flow is further reduce by another restriction device placed along the compensator circuit between the compensator valve and the clutch drums.

Abstract: A two-handle faucet includes a faucet body, a faucet housing, and a faucet base. The faucet body includes two valve core assemblies, a tee connector, a water outlet pipe, and two water inlet pipes. The water inlet pipes are insertedly connected to the faucet base. The water outlet pipe is hermetically connected to the tee connector. The water inlet pipes are connected to the tee connector through the two valve core assemblies. The valve core assemblies are responsible for the passing of water. The faucet base is only used for supporting the faucet, and the water won't pass through the faucet base. The faucet is safe for use and has sufficient strength, so that the product performance is stable and the cost can be reduced.

Valve assemblies comprise the pivot valves and flapper valves and have an open condition, a check condition, and a shut-off condition.

Abstract: A medical cleaning valve (or cleaning valve) may be configured to provide cleaning functionality to fluid (e.g., air and water) channels of an endoscope. Many embodiments described herein may include a cleaning valve (or valve) that is appropriate for single-use and therefore may be disposable. Accordingly, the valve may be made from a limited number of parts and materials, e.g., to limit its cost and/or manufacturing complexity. For example, multiple seals may be integrally formed with a valve stem. In another example, the valve may have an interface member, which may combine and simplify the functionality of a number of components, such as by connecting the valve stem to a valve well, sealing an opening to a lumen in the valve stem, and/or biasing the valve stem into a position relative to the valve well.

Abstract: A valve connector includes a connecting member, a threaded member, a joint member, and first and second connection assemblies. The connecting member is inserted into an axial hole of the threaded member to cause an abutting portion of the connecting member to enter into the axial hole.
