摘要： Disclosed is a hydraulic pilot valve which is provided with an orifice so as to reduce vibration of a valve and minimize impact applied to a valve even when a valve is suddenly operated. At least some of hydraulic oil supplied to a supply chamber flows to a valve chamber or a central pipeline through a damping unit according to elevation of a spool.

摘要： A sanitary insertion unit (1), including an insertion housing (6), in which insertion housing a valve having a valve piston (10) is provided, which valve piston is slidably guided in the insertion housing and can be moved from a resting position under the pressure of the inflowing water against the restoring force of at least one restoring element (11). The restoring unit has at least one movement damper (12, 13), which damps or brakes the movement of the valve piston from the resting position to the open position.

摘要： A method for switching over a solenoid valve having a movable valve body between a first position and a second position, wherein the method comprises at least the following method steps: a) adjusting a switching current to a pre-energization current intensity, in which the valve body remains in the present position, for a first time interval, and b) adjusting the switching current to a first switchover current intensity, which introduces a switchover movement of the valve body, for a second time interval.

摘要： The hydraulic damping device includes: a cylinder storing fluid; a piston configured to form a channel through which the fluid flows along with relative movement of a rod relative to the cylinder in a specific direction; a valve having elasticity, the valve being configured to open and close the channel in the piston; a movement permitting part configured to permit the valve to move between a contact position and a spaced position, the contact position being a position where the valve contacts the piston, the spaced position being a position where the valve is spaced from the piston; a restricting part configured to restrict bending of the valve at the spaced position; and a pressing part having elasticity, the pressing part being configured to press the valve against the piston.

摘要： Devices and systems for exchanging properties between at least two fluid streams and related methods may include a valve device comprising a valve actuator configured to move at variable rates in order to selectively fill and empty at least one tank. Devices for exchanging properties between at least two fluid streams may include a valve device comprising offset openings positioned along a path of a valve actuator. The offset openings may be configured to selectively and gradually place an inlet in communication with at least one tank.

摘要： A fluid control valve includes: a valve main body including a circulation hole through which a fluid flows and a yoke that has a valve seat provided in the circulation hole and has magnetism; a valve body controlling flow of the fluid by abutting on the valve seat when the valve body is seated and separating from the valve seat when the valve is opened, and having magnetism; an electromagnetic coil provided on the valve main body, and generating a magnetic field to attract the valve body to the valve seat; and a buffer member that abuts on the valve body that moves in a valve closing direction to reduce a moving speed of the valve body after a valve closing operation is started and before the valve body is seated.
