Abstract
A solenoid valve has a housing, including a fluid chamber and a drive chamber, a diaphragm, which separates the fluid chamber from the drive chamber, an actuator and a setting element, which is mounted in the housing for pivoting movement about an axis of rotation by means of the actuator between a first position, in which a valve seat of the solenoid valve is closed, and a second position, in which the valve seat is open. The diaphragm has a fastening portion which is clamped between two housing parts and by means of which the diaphragm is fastened to the housing. The diaphragm is formed from a thermoplastic and the axis of rotation runs through the fastening portion.
