摘要: A spool valve (1) includes: a sleeve (10) extending in an axial direction thereof, including an inlet port (11) and an outlet port for working fluid; a spool (20) movably housed in the sleeve (10) in the axial direction; a biasing device (30) including a spring (31) as a biasing member configured to press a base end (20a) of the spool (20) toward a tip end (20b) of the spool (20); and a pressure detecting port (56) for the working fluid, opening toward the tip end (20b) of the spool (20). The outlet port (12) is constituted of slits (16), and the slits (16) are arranged at intervals in the circumferential direction of the sleeve (10) and extended in the axial direction.

摘要: A flow regulator comprising a housing having a first chamber, a second chamber and a valve seat which is arranged between these chambers, a valve head which is arranged in the first chamber and which has at least a first surface which faces the first chamber, a second surface which faces the second chamber when the valve head is in a closed position and a through-hole between the first surface and second surface, the valve head being movable between an open position and a closed position, a shaft which is capable of moving the valve head between the open and closed positions, and an engaging pin which is at least partially received in the hole of the valve head in a sliding manner, the engaging pin being capable of moving with respect to the valve head between at least one non-sealed position and one sealed position, and being in this at least one non-sealed position when the valve head is in the open position and being capable of moving into the non-sealed position when the valve head is in the closed position.

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 gas solenoid valve includes: a housing; a main valve body; a guide member; a first biasing member that is disposed in a housing space formed inward of the guide member to surround the main valve body and biases the main valve body in an opening direction; a second biasing member; and an electromagnetic drive device. The housing space is spaced apart from one end of the guide member in the opening direction. A buffer groove is formed at the one end of the guide member to surround an opening end of an inner hole of the guide member.

摘要: A valve includes a valve body having a valve plunger barrel formed therein and configured to be mounted to a pump head of a fuel pump, a valve plunger arranged to perform reciprocal motion with respect to the valve plunger barrel, a drive assembly configured to cause the valve plunger to perform reciprocal motion, and a spacer configured to couple to the valve plunger to perform reciprocal motion together with the valve plunger and configured to interface with the pump head. The spacer has a spacer body with first and second opposing spacer surfaces and with a central aperture extending from the first to the second spacer surface and configured to receive the valve plunger therethrough. At least one of the first and second spacer surfaces includes one or more grooves recessed into the spacer body to reduce or inhibit cavitation of the interface of the spacer and pump head.

摘要: A water arrestor valve assembly permits the servicing and/or replacement of a water hammer arrestor in a segment of a plumbing system. The water hammer arrestor can be isolated from the incoming and outgoing water supply by a valve or a tee-shaped valve body. In addition, the bleeder drain valve(s) can be located on the tee-shaped valve body to reduce the pressure and drain fluid before removal of the water hammer arrestor and can also be used to isolate, reduce the pressure and drain the length of piping of the fixture/appliance that is downstream of the water hammer arrestor.

摘要: A valve assembly for an exhaust system of a vehicle comprises a housing defining an inlet, an outlet, and a longitudinally extending exhaust gas passageway in fluid communication with the inlet and the outlet. The valve assembly further comprises a valve flap disposed in the housing and rotatable between a first position restricting exhaust gas flow through the exhaust gas passageway, and a second position whereat exhaust gas flow through the exhaust gas passageway is less restricted. A mass damper is disposed within the exhaust gas passageway and attached to the valve flap. The mass damper includes end portions and an intermediate portion disposed between the end portions with the intermediate portion having a thickness that is greater than a thickness of the end portions. The mass damper is positioned proximate an inner surface of the housing and positioned between the valve flap and the housing when the valve flap is at the second position.

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.
