An electromagnetic switch valve for opening or closing an oil or coolant circuit in a motor vehicle, having an electromagnet, which has a coil and a movable armature, wherein the armature is coupled to a valve element, via which a valve seat in the coolant circuit can be sealed, wherein the switch valve is designed to be pressure balanced, and the valve element, pointing in the direction of the valve seat, is designed to be at least approximately hollow-walled.

Electromagnetic solenoid valve

The application relates to a valve for a line system, comprising a valve body which forms a valve seat, a line system with a supply line for supplying a fluid to the valve seat and with a discharge line for discharging the fluid from the valve seat, which fluid is under a supply pressure in the supply line and under a working pressure in the discharge line, a closing element which interacts with the valve seat for opening and closing the line system, which closing element releases a throttle cross section between the valve seat and the closing element, a restoring element which applies a restoring force on the closing element, which restoring force presses the closing element against the valve seat in order to close the line system, and a pressure chamber in which the fluid is under a closing pressure to close the line system.
