摘要： A valve device includes a housing, a stationary disk, a drive device, a shaft and a rotor. The stationary disk is fixed at an inside of the housing and has at least one flow passage hole. The shaft is rotated about a central axis by the drive device. The rotor increases or decreases an opening degree of the at least one flow passage hole. The rotor includes: a drive disk that slides relative to the stationary disk; and a lever that is fixed to the drive disk and couples between the drive disk and the shaft. A first torsion spring is placed between the housing and the shaft and urges the shaft relative to the housing in a circumferential direction around the central axis, and a second torsion spring is placed between the shaft and the lever and urges the lever relative to the shaft in the circumferential direction.

摘要： A pressure control valve may include a valve body, a fixed cylinder and a rotating cylinder. The valve body may have an inlet port and an outlet port. The fixed cylinder may be fixed to an inner wall of the valve body. The fixed cylinder may include a quadrangular first fixed hole connected to the inlet port, and a quadrangular second fixed hole connected to the outlet port. The rotating cylinder may be rotatably arranged in the fixed cylinder. The rotating cylinder may include a quadrangular first pressure control hole selectively connected to the first fixed hole, and a quadrangular second pressure control hole selectively connected to the second fixed hole. Thus, the pressure control valve including the quadrangular fixed hole and the quadrangular pressure control hole may have improved pressure control function.

摘要： A control valve including a valve body, a chamber arranged inside the valve body, a fluid inlet, a fluid outlet, and a closing arrangement for regulating the flow of fluid from the fluid inlet to the fluid outlet via the chamber. The closing arrangement has a closed state in which no fluid, or only a leakage flow, is allowed to flow through the chamber, a first open state in which fluid is allowed to flow through the chamber, and at least one second open state in which a lower flow of fluid is allowed to flow through the chamber compared to when the closing arrangement is in its first open state. Between the closed state and the second open state, the closing arrangement is configured to allow fluid to flow through the chamber in accordance with a first valve characteristic function.

摘要： A method of designing a valve presenting an orifice of section that depends on the position of the valve member of the valve, which section can thus be controlled. The method includes determining a desired variation relationship for the flow section of the valve, which relationship defines a desired variation in the section as a function of time; setting a predetermined movement relationship for the valve member; and defining the shape of the fluid flow orifice in such a manner that, at each instant, if the valve member moves in compliance with the predetermined movement relationship, the flow section remains equal to the desired section. The method makes it possible to design a valve that is simple to control.

摘要： A flow-adjusting valve including a valve base and a valve rod. The valve base has arranged within a valve cavity thereof a valve opening. The valve rod opens or shuts the valve opening. The valve rod is tube-shaped, and the lower part thereof is a cylinder. The valve base has arranged at circumferential positions around the valve opening a sealing stepped surface. A lower end face of the valve rod is sealedly in contact with or disengaged from the sealing stepped surface. Furthermore, the valve opening has protruding upwards along the axial direction thereof a sleeve protrusion part. The sealing stepped surface is arranged within the sleeve protrusion part. The structure of flow-adjusting valve on the one hand balances a refrigerant pressure exerted along the axial direction of the valve rod while on the other hand improves the service life and sealing performance of the valve rod.
