摘要： Disclosed is a solenoid valve, in which a rod is moved by a plunger that comes into contact with and separates from a stator by electromagnetic force, causing a valve body that opens and closes a valve to move reciprocally. The valve is configured such that a first space and a second space are formed at respective sides of the plunger in the movement direction thereof, a through-hole is formed in the plunger so as to be concentric with a center axis, the rod is arranged in the first space, and a communication passage is formed between an inner surface of the plunger and an outer surface of the rod and communicates with the first space S1 and the second space.

摘要： A solenoid valve includes a main valve having a valve seat and a main valve body configured to open or close a main flow passage, a pilot passage that branches from the main flow passage, an orifice provided in the pilot passage, a back-pressure chamber configured to bias the main valve body to a closing direction by virtue of an internal pressure, a pilot valve configured to control an internal pressure of the back-pressure chamber, and a solenoid configured to control a valve opening pressure of the pilot valve. There is a time difference between a valve opening timing of the main valve and a valve opening timing of the pilot valve such that the valve opening timing of the main valve is delayed from the valve opening timing of the pilot valve.

摘要： An electromagnetic actuator includes an armature and an anti-saturation and damping shim. The armature is slidably actuatable and includes a central aperture providing fluid communication longitudinally along the armature. The anti-saturation and damping shim is configured to both dampen the actuation of the armature within an electromagnetic actuator and prevent the armature from making unwanted contact with other magnetic objects.

摘要： An electromagnetically actuated piston slide valve includes a piston slide arrangement with a piston which is axially displaceable for regulating a free cross section of a fluid passage of the valve. The piston slide arrangement contains a first magnetic armature connected to the piston and a second magnetic armature which is axially displaceable with respect to the piston. The piston is axially displaceable against the force of a first biasing spring by generating an electromagnetic field through energizing a coil. A second biasing spring rests against the first magnetic armature and the second magnetic armature, so, in the unenergized state of the coil, the piston takes a predetermined position by axial displacement due to the force of the first biasing device against the force of the first biasing device. A permanent magnet generates an attractive force between the first and the second magnetic armature which counteracts the second biasing spring.

摘要： An electromagnetically or electrically operated valve possesses a closing element that is axially displaceable between a closed position and an open position. The closing element is pressure-compensated, by the pressure present on the front side of the closing element being passed to the back side thereof. Between the front and back sides the closing element is sealed radially against a surrounding structural element by means of a dynamic seal. The circumferential sealing gap varies in width in dependence on the axial position of the closing element, so that the dynamic seal seals reliably only in the closed position, while in other positions the static friction of the dynamic seal is reduced.

摘要： The invention relates to an electromagnet 1 of an electromagnetically actuated fluid valve 2. The electromagnet 1 has a magnet core 17 which receives a coil 18 and an armature unit 19 which can be moved axially to the coil 18 in the magnet core 17. The electromagnet further has a device for damping a stop of the armature unit 19 against the magnet core 17. According to the invention, an electromagnet 1 is provided which is permanently improved with respect to the noise emanating from said electromagnet. This is achieved in that the device has a flow cross-section 28 for a medium, said flow cross-section decreasing when the armature unit 19 is moved. The cross-section is formed by a cone 26 which interacts with a counter surface 27.
