An electromagnetic valve includes a solenoid with a bobbin, a plunger, a yoke, and a coil, a flow path assembly including a first flow path, a second flow path, and a valve housing portion, and a valve that switches between an open state and a closed state between the first flow path and the second flow path. The plunger includes a passage that extends along an axial direction, and that opens toward another axial side to communicate with a gap between the plunger and the yoke, and an opening that opens radially outward from the passage to allow the passage communicating with the gap to communicate with the valve housing portion through the passage. The electromagnetic valve further includes a regulator to regulate a radially outward flow of a fluid flowing out from the passage into the gap at least in the open state.

A plate armature damping device for a tilting armature valve includes at least one damping body which can be fixed to a plate armature, with at least one damping material which, on an impact movement of the plate armature in the direction of a counter-element, is elastically deformable on impact on the counter-element. The at least one damping body has a geometric contour including at least one bulge on a surface of the at least one damping body facing the counter-element, which is configured such that, on the impact movement of the plate armature, the volume of the at least one damping body contributing to the damping increases.

A fuel tank isolation solenoid valve for a vehicle includes: a plunger disposed in the isolation solenoid valve to be vertically moved and has first vent holes for releasing overpressure or over-negative pressure; a valve body disposed in the isolation solenoid valve to be vertically moved and has second vent holes for releasing overpressure or over-negative pressure.

A valve can include a solenoid coil, a plunger having a core configured to respond to a magnetic field generated by the solenoid coil, and a valve disc. The valve disc can be positioned at a head of the core and configured to cushion impact when the valve is closed. A projection can be positioned and configured to cushion impact when the valve is opened. The valve can be used in an air bed system in fluid connection between an air pump and an inflatable air chamber of a mattress.

A solenoid valve, in particular for controlling a brake pressure of a wheel brake of a motor vehicle, includes a pole core, an axially moveably mounted armature, a valve element, a closure element, a plunger, and a pressure spring. One end of the armature is associated with the pole core. The valve sealing element is arranged at another end of the armature. The armature has an axial through-opening. The closure element is force-lockingly and/or interlockingly retained in the axial through-opening in a selectable position. The plunger is axially moveably mounted in the axial through-opening, which provides a connection to the pole core in an installation position. The pressure spring is positioned in the axial through-opening and is retained in a pretensioned manner between the plunger and the closure element. The closure element is designed as a three-dimensionally convex element.

A solenoid valve for brake system includes a valve housing installed in a modulator block, and having an oil flow path; a valve seat installed in the inside of the valve housing, and forming an orifice; an armature configured to move up and down by a magnet core in the valve housing, and to open or close the orifice; a sleeve coupled with the valve housing, and accommodating the armature therein; a restoring spring configured to provide an elastic restoring force to the armature to close the orifice normally; and a damper member interposed between the magnet core and the armature.

A valve for metering fluids, for fuel injection valves for internal combustion engines, includes an electromagnetic actuator in a housing and a valve needle actuatable by an armature of the actuator, which actuates a valve closing body interacting with a valve-seat surface to form a sealing seat. The armature is movably guided on the valve needle. A stop element connected to the valve needle limits, with an actuation of the valve needle, a relative motion between the armature and the valve needle. The stop element includes at least one elastically deformable part and one stop piece, the elastically deformable part being shaped as a sleeve, and the stop element being configured so that the armature, upon the limitation of the relative motion between the armature and the valve needle, initially contacts the elastically deformable part and impacts the stop piece after a corresponding elastic deformation of the elastically deformable part.

An electromagnetic pressure control valve including an electromagnetic actuator configured to position a piston that is received axially movable in a receiving opening of a valve housing of the electromagnetic pressure control valve, wherein the piston facilitates opening and closing flow connections of the electromagnetic pressure control valve, wherein the piston receives a pin at a piston face that is oriented away from the electromagnetic actuator, wherein a relative movement is enabled between the pin and the piston, wherein the pin includes a pin face that is arranged in the valve housing and oriented away from the piston and arranged opposite to a stop, and wherein the pin is fixed at the stop so that a movement of the pin in a direction towards the stop is eliminated.

A valve can include a solenoid coil, a plunger having a core configured to respond to a magnetic field generated by the solenoid coil, and a valve disc. The valve disc can be positioned at a head of the core and configured to cushion impact when the valve is closed. A projection can be positioned and configured to cushion impact when the valve is opened. The valve can be used in an air bed system in fluid connection between an air pump and an inflatable air chamber of a mattress.

The disclosure relates to a solenoid valve comprising a housing body made of a thermoplastic, a coil, and a metal yoke which is at least partly arranged about the coil, wherein the housing body is designed as an injection molded part which surrounds the coil, and electrically insulating additives are added to the thermoplastic in order to increase the thermal conductivity thereof. The housing body is formed with grooves on the housing body exterior, and the metal yoke is designed as a component which partly surrounds the housing body and is mechanically connected to same.
