Abstract
The solenoid valve has two fluidic connections (3, 4), a solenoid (5) and a core (8) guided in a cylinder (7) within the solenoid body (6). The solenoid valve (1) is opened as a result of the movement of the core (8) when the solenoid (5) becomes magnetized. After disconnection of the solenoid (5), it is closed due to the force of a spring (27). Both the core and the closing device of the valve (1) are pressure-relieved, in that the end face of the core (8) has an effective surface which corresponds to an effective surface (18) at the valve body (14). The elastic main seat seal (20) is contained in the housing (2). The taper-ended main valve seat (13) and the compensation diameter (12) are housed in combination within a movable seat bushing (11).
