摘要： A fuel pressure regulator includes a fuel inlet; a fuel outlet; a seating surface; and a valve member assembly. The valve member assembly includes a poppet and also includes a sealing member which is made of an elastomer material and which is annular in shape and including a sealing member surface. The sealing member is supported by the poppet. The valve member assembly is moveable between 1) a closed position in which the sealing member surface engages the seating surface, thereby preventing fuel flow from the fuel inlet to the fuel outlet and 2) an open position in which the sealing member surface is spaced apart from the seating surface, thereby allowing fuel flow from the fuel inlet to the fuel outlet.

摘要： Two-way pressure relief valves featuring dual poppets and magnets that allow very rapid flow. Such flow is accomplished by a valve housing enclosing a hollow interior portion containing a stationary member including a magnet and a first pressure-movable poppet disposed in sealing arrangement with the housing and including a second magnet. To provide flow in the other direction, a second moveable poppet disposed coaxially and in sealing arrangement with the first poppet and is coupled to a spring that extends from a first end of the second poppet to a support structure coupled to the second magnet.

摘要： A regulator may include a fuel inlet from which a high-pressure fluid is introduced, a valve seat provided at the fuel inlet, and a pressure regulating valve body. The fluid may pass an opening between the valve seat and the pressure regulating valve body formed with a communication passage to a pressure regulating chamber provided to face a valve-seated seat arranged on the pressure regulating chamber side of the valve seat. A load generated by pressure of pressure-regulated fluid acting on a piston unit joined to the pressure regulating valve body may be balanced with a load by a pressure regulating spring in an atmosphere chamber provided coaxially in parallel with the pressure regulating chamber on an opposite side of the pressure regulating chamber of the piston unit. Fluid pressure of the pressure regulating chamber may be controlled by changing an opening area between the valve-seated seat and the pressure regulating valve body. The valve seat holding the valve-seated seat may be installed on an elastic member via a buffer having a sliding performance for automatic alignment to enable uniform contact between the pressure regulating valve body and valve-seated seat.

摘要： A damping valve includes a damping valve body having at least one throughflow orifice which is at least partially covered by at least one valve disk by the action of a closing force. At least one spring body exerts an opening force on the valve disk that is less than the closing force. The at least one spring body is constructed as an elastomeric body separately from the control edge.

摘要： A vacuum large-capacity electrically controlled proportional valve includes a main body having a valve bottom seat, a middle valve seat, and a guide seat and has a vacuum pressure chamber, in which a main diaphragm is arranged with an elastic element provided thereon to connect with the guide seat. A pilot discharge straight rod is fit to a center of the main diaphragm. The main body includes a master channel connected to a guide channel and a feedback channel Provided above the guide seat are a vacuum pressure electromagnetic valve, an atmospheric pressure electromagnetic valve, and a sensor. The guide seat includes a regulation channel connected to the vacuum pressure chamber. A pilot atmosphere channel is connected to a space under the main diaphragm. A first and a second vacuum destruction valve gates are provided and driven by an external atmospheric pressure for speeding up decrease of interior vacuum level.

摘要： A flow control valve including a valve body, stepper motor, and valve member. The valve member includes a poppet that can slide longitudinally within a bore of the valve body when the stepper motor receives electricity. A diaphragm, extending inwardly from the valve body to the valve member, deflects in response to movement of the valve member. A flow control needle, mounted to the poppet of the valve member, is at least partially received in an outlet port of the valve body. The flow control needle cooperates with an inner surface of the outlet port to define an outlet flow orifice that varies in size when the valve member moves between open and closed positions. In the closed position, a seat engagement surface of the valve member contacts a valve seat of the valve body to create a fluid-tight seal.

摘要： A poppet valve system that includes a valve body having a first and second end and defining a valve cavity and a poppet assembly extending from the first end to the second end and through the valve cavity. The poppet assembly can include a movable poppet head disposed at the first end of the poppet assembly and configured generate a seal by contacting a portion of the valve body and configured to define an opening between the valve cavity and a pressure cavity. The poppet assembly can also include a movable guiding element disposed at the second end of the valve body and a shaft extending from the first end to the second end and coupled to the poppet head and guiding element.

摘要： The present invention relates to a safety valve including: a tube intended to be fixed to a watch case, a hollow head mounted for rotation about the tube, a first element fixedly mounted with respect to the head and a second element integral with the head, wherein the first element and the second element each include one or more passages allowing gas to flow, the rotational motion of the head allowing the passages of the first element and of the second element to be placed in communication for gas to escape from the interior to the exterior of the case in case of overpressure inside the case or, conversely, allowing the passages of the first element and of the second element to be moved out of alignment to prevent gas escaping.

摘要： Disclosed is a method and a unit (10) for the regulation or control of a fluid pressure, having at least one housing section (13, 14) and a switching film (22) connected to the at least one housing section (13, 14) for switching at pressure differentials of 1 to 250 mbar, preferably from 1 to 100 mbar, relative to an ambient pressure acting on the switching film (22), and for the regulation, release or blocking of a flow of the fluid between an inlet (28) and a discharge (30) for the fluid. The switching film (22) is made out of a polymer material having fluorine and carbon. In this arrangement, a hole cross-section (40) of the at least one housing section (13, 14) is closed off by the switching film (22).

摘要： A drive device includes a rotor, a stator, a housing including an accommodation portion to store oil and accommodate the rotor and the stator, a pump driven through a motor shaft, and a valve in the housing. The pump includes a pump room in the housing, a suction port through which the oil is to be sucked into the pump room, and a discharge port through which the oil is to be discharged from the pump room. The housing includes a first oil passage connected to the discharge port and a branch oil passage that is connected to the first oil passage and is open to an inside of the accommodation portion on an upper side in a vertical direction of the stator. The motor shaft includes a second oil passage located in the motor shaft and connected to the first oil passage and a first through-hole connecting the second oil passage and an outer circumferential surface of the motor shaft. The valve is provided in the branch oil passage, and switched between a closed state in which a flow of the oil in the branch oil passage is blocked and an open state in which the flow of the oil in the branch oil passage is permitted.
