Abstract:
The invention relates to an electromagnetic valve, in particular for a gas bottle for gas-operated motor vehicles, having • a main part; • a pressure sleeve (13) which is closed on one side and is fastened to the main part; • a coil (17) surrounding the pressure sleeve (13); • at least one armature (22, 23) arranged in the pressure sleeve (13); • and at least one blocking piston (9) which is accommodated in the pressure sleeve (13) in an axially movable manner and has a main seal (10) which can be pressed against a main seal seat of the main part. In order to prevent undesired noise generation, according to the invention the axially movable blocking piston (9) and the pressure sleeve (13) have interlocking guide elements (25, 26), which guide the blocking piston (9) on the pressure sleeve (13) so as to prevent rotation.
