摘要： A check valve (1) is described, the check valve (1) including a valve housing having a first port (2) and a second port (3) connected to a valve chamber (4), a valve seat (5) having a valve seat axis (6) and being arranged between the first port (2) and the valve chamber (4), and a valve element (7) movably arranged within the valve chamber (4) between the valve seat (5) and a stop face (8) opposite the valve seat (5), wherein the valve housing includes a first part (9) having the first port (2) and a second part (10) having the second port (3) and being connected to the first part (9). Such a check valve should have a simple design. To this end the second port (3) opens into the stop face (8) by means of an array of holes (12), wherein the cross section area of the holes (12) is smaller than the smallest cross section area of the valve element (7).

摘要： One or more systems are disclosed for a diaphragm pump. The diaphragm pump includes a valve inlet portion elongated in a first direction along a longitudinal axis, and a valve outlet portion coupled to the valve inlet portion. A ball check valve is arranged between the valve inlet portion and the valve outlet portion. The ball check valve includes a sealing ring arranged over the valve inlet portion, and a ball arranged over the sealing ring. The ball is configured to move between a seated position and an unseated position, wherein a central axis of the ball extends through a center of the ball and in the first direction, wherein the central axis is coincident with the longitudinal axis when the ball is in the seated position, and wherein the central axis is offset from the longitudinal axis when the ball is in the unseated position.

摘要： A dual pressure pump system for a transmission includes a dual pressure pump having a first pump outlet and a second pump outlet, and a pressure regulator valve defining a first chamber in fluid communication with the first pump outlet and a second chamber in fluid communication with the second pump outlet. The pressure regulator valve is configured to selectively connect the first chamber with a first pressure line operating at a first greater-than-zero pressure and to selectively connect the second chamber to a second pressure line operating at a second greater-than-zero pressure.

摘要： The present application relates to an apparatus of joined valves used to test and maintain refrigeration systems. More particularly, the present application provides a Multiple Valve Refrigerant Leak Protection Device having a specifically preferred embodiment including a ball valve with a soldered pipe connection, as part of the fitting with a Schrader valve, primarily used for the maintenance and transfer of refrigerant from commercial refrigeration equipment. Schrader valves are most commonly used in this application with a ball valve. A ball valve would be the preferred valve, but a wide range of valves could be used. The resulting valves can be used to test and maintain refrigeration systems, and act to prevent leakage where refrigeration fluids are often released to the atmosphere when the system is being maintained or repaired.

摘要： A valve configured for use with a fuel tank can have a floating main valve housed within a valve body. The valve body can define a first port fluidly connected to the fuel tank, a second port fluidly connected to a tank venting system of the fuel tank and a third port fluidly connected to the filler neck. The solenoid can be configured on the check valve. The solenoid can have a pin configured to extend into the valve body and engage the floating main valve in a locked position.

摘要： A homogenization device having an inlet valve, a flow-through chamber and a discharge valve. A baffle element reciprocatingly moves between an upstream portion and a downstream portion of the flow-through chamber. When the baffle element moves downstream, the inlet valve opens and liquid is admitted into the upstream portion. When the baffle element moves upstream, the inlet valve closes, the liquid in the upstream portion is pressurized and forced to flow downstream through a gap or local constriction between the outer perimeter of the baffle element and the inner surface of the chamber, causing cavitation bubbles to form and collapse.
