摘要： A variable orifice flow device controls the flow of a fluid between a volute casing and a compressor motor casing in a compressor. The variable orifice flow device may be a shuttling valve, with positions controlled by, for example, valves controlling the flow of the fluid into a space opposite a side within the shuttling valve assembly. The variable orifice flow device may have one or more orifices through which a fluid can enter the compressor motor casing, and the surface area of the orifices may be controlled by the position of the shuttling valve.

摘要： An in-line valve, particularly suited for use with a domestic garden hose, comprises a valve body, preferably made of two press-fitted-pin mating parts. A shuttle moves linearly within the bore of the valve body when force is applied to tabs which project through openings in the valve body. The end of the shuttle sealingly engages and disengages with a plug that is centered within the bore. The plug comprises struts and fins, configured for good flow characteristics. The combination of cross section of the shuttle relative to the bore, and the fits and properties of O-ring seals, are critical for easy manual operation of the valve.

摘要： A system includes a choke valve, an actuator configured to adjust a position of the choke valve, a variable frequency drive configured to adjust a speed at which the actuator adjusts the position of the choke valve, and a controller configured to receive first feedback indicative of a fluid pressure upstream of the choke valve, compare the first feedback to a first predetermined pressure range, and instruct the variable frequency drive to send electricity to the actuator at a first frequency when the first feedback is outside of the first predetermined pressure range, where the variable frequency drive is configured to control a speed and a direction of the actuator such that the actuator adjusts the position of the choke valve to a first position at a first speed, and where the first speed is based at least on a difference between the first feedback and the first predetermined pressure range.

摘要： A water-saving device for a faucet has a main body. A flow-controlling member and a movable flow-blocking member are mounted in the main body. The main body has multiple receiving holes that receive respectively multiple positioning balls. A driving member movably receives an outer surface of the main body. When the faucet is open, the flow-controlling member and the flow-blocking member facilitate a water flow that is adjustable and stable. A user pulls the driving member downwards for increasing the water flow as required. The positioning balls are mounted in the driving member. The flow-blocking member that is pressed by the water flow moves downwards. When the faucet is closed, the flow-blocking member restores to an original position, thereby automatically adjusting the faucet to a minimum water flow for next use and economizes the water usage.

摘要： Ventilation systems and gasper valves for ventilating passenger compartments of aircraft are disclosed herein. The ventilation system includes, but is not limited to, an air supply conduit and a gasper valve. The gasper valve includes a poppet and an annular nozzle. The poppet is configured to move between a closed position and an open position and defines a sealing surface. The annular nozzle has a nozzle throat opposing the sealing surface of the poppet. At least one of the sealing surface and the nozzle throat comprises a flexible material configured to at least partially deform in the closed position to restrict air leakage between the poppet and the annular nozzle.

摘要： Axial fluid valves having annular flow control members are described herein. An example axial fluid valve described herein includes an axial flow valve body defining a passageway between an inlet and an outlet. The example axial fluid valve includes a sleeve slidably received by an inner surface of the axial flow valve body and movable along an axis substantially parallel to a longitudinal axis of the passageway. The example axial fluid valve includes a linkage or a gear operatively connected to the sleeve to move the sleeve to vary a flow of fluid between the inlet and the outlet through the sleeve.

摘要： A rotary-to-linear motion actuator having helical bevel gear and methods of use thereof are described. The actuator may be utilized with an apparatus for managing a fluid flow passage between one or more input ports and output ports. A pinion gear engages, and during operation turns, a bevel ring gear arranged on a helical path along an external periphery of a sleeve retaining a seat, which forms a fixed orifice. The teeth of the bevel gear are arranged on the helical path at the same pitch as external threads on the sleeve, which in turn, engage internal threads in an apparatus body. The area of the flow passage is changed by movement of the fixed seat orifice axially with respect to a contoured plug assembly. The threads of the sleeve and the body resist axial load imparted by the pressure drop across at the fixed orifice.
