摘要： Systems and methods are provided and include a compressor for a refrigeration system and a duct assembly that includes a duct frame and a sensor unit. The duct frame provides a path for evaporating refrigerant from a lubricant sump of the compressor. The sensor unit obtains temperature measurements of the refrigerant and a lubricant within the lubricant sump and heats and evaporates the refrigerant located within the duct frame of the duct assembly. A control module receives temperature measurements from the sensor unit, determines a presence of liquid refrigerant within the lubricant sump of the compressor in response to a determination that an actual temperature change does not correspond with an expected temperature change for the lubricant, and in response to a determination that the actual temperature change corresponds with the expected temperature change for the lubricant, operates the compressor.

摘要： A pulsation damper configured to reduce pressure peaks in a pipe system. The pulsation damper comprises an elastic pipe section arranged to be in a small volume state or a large volume state. A first volume held in the elastic pipe section in the large volume state is greater than a second volume held in the elastic pipe section in the small volume state. The elastic pipe section has an elliptical cross section in the small volume state. A ratio between a major axis and a minor axis of the elastic pipe section is in the range 1,05 to 10,0, such as 1,1 to 1,5.

摘要： Disclosed is a water piping system. More particularly, the present invention relates to a water piping system having a function to dampen the effects of water hammer and check valve slam at a sudden stoppage of a pump and relates to a tank connector therefor, in which the water piping system ejects a high pressure jet stream from a high pressure tank in the direction of a primary flow in a main pipeline, thereby deterring the backflow of pipeline water in the main pipeline and reducing the pressure of pipeline water against a check valve, which enables the check valve to be slowly closed.

摘要： There is provided a tube pump system including: a pair of roller units rotated around an axis line from a contact position to a separate position; a pair of drive units rotating the pair of roller units respectively; and a control unit controlling each of the pair of drive units. A pipe having flexibility is connected to an outflow-side end portion of the tube, and the pipe maintains a pressure of a liquid flowing through the inside of the pipe at a first predetermined pressure higher than an atmospheric pressure. The control unit controls each of the pair of drive units such that a pressure of the liquid in the tube closed due to a contact of the pair of roller units is increased to a second predetermined pressure when one of the pair of roller units passes the separate position.

摘要： A fuel pump having a housing defining a pump chamber and an inlet and outlet fluidly connected to the pump chamber. A one way check valve is disposed fluidly in series between the pump chamber and the outlet and is oriented to allow fluid flow from the pump chamber and to the outlet when the check valve is open. A venturi tube is fluidly connected in series between the pump chamber and the outlet which effectively dampens noise pulsations. An inlet valve to the pump chamber has an anchor attached to a valve member and the stationary core. A conical surface on the core abuts against a complementary conical surface on the anchor when the valve is either in its fully open or fully closed position.

摘要： A housing for use in high pressure fluid applications comprises a first drilling having a region of enlarged diameter bounded by an upper boundary in a first plane and a lower boundary in a second plane; and a second drilling intersecting with the first drilling via an intersection region. The intersection region includes a first substantially flat surface which defines a ceiling of the intersection region and which intersects the upper boundary of the region of enlarged diameter, and a second substantially flat surface which is opposed to the first substantially flat surface and which defines a floor of the intersection region and intersects the lower boundary of the region of enlarged diameter. As the flat surfaces are in alignment with a region of maximum hoop stress they do not act as a significant stress raiser at the intersection.

摘要： A piston pump as a return pump of a slip-controlled, hydraulic vehicle braking system is disclosed. There is a mushroom-shaped shut-off body as a spring-loaded outlet valve, the shaft thereof extending through a center hole of a tubular damper piston. The shut-off body is movable transversely to the opening and closing direction thereof, so that said shut-off body aligns with a valve seat upon closing. Upon opening, the damper piston forces brake fluid out of a damping chamber in which it is housed so that an opening movement of the outlet valve is dampened.

摘要： An apparatus for providing a selectively variable orifice size for pulsation control in a reciprocating compressor system includes a rotatable upper windowed plate and a fixed lower windowed plate, the windowed plates being aligned a long a central axis to form a central cylindrical port. The upper and lower windowed plates each include at least one plate port and have mating contours allowing the upper plate to rotatably slide over the fixed lower plate, allowing their respective ports to be selectively aligned in any configuration to create any desired orifice size for a pulsation control device. The shapes of the windowed plates can be flat, conical, or any combination thereof. In one embodiment, the upper and lower windowed plates each include a plurality of plate ports which can be selectively aligned, the relative alignment of the plurality of plate ports determining the effective orifice size of the pulsation control device.
