Abstract
The solenoid valve has two fluidic connections ( ), a solenoid ( ) and a core ( ) guided in a cylinder ( ) within the solenoid body ( ). The solenoid valve ( ) is opened as a result of the movement of the core ( ) when the solenoid ( ) becomes magnetized. After disconnection of the solenoid ( ), it is closed due to the force of a spring ( ). Both the core and the closing device of the valve ( ) are pressure-relieved, in that the end face of the core ( ) has an effective surface which corresponds to an effective surface ( ) at the valve body ( ). The elastic main seat seal ( ) is contained in the housing ( ). The taper-ended main valve seat ( ) and the compensation diameter ( ) are housed in combination within a movable seat bushing ( ).
