Elektromagnetventil, insbesondere für schlupfgeregelte Kraftfahrzeugbremsanlagen

摘要

The invention relates to an electromagnetic valve having a valve housing (2) which comprises a plurality of valve components, such as a valve closure member (11), mounted on the valve tappet (6), and an armature (5), the valve components adapted for the function of the electromagnetic valve. The valve closure member (11) can be applied against a valve seat and the armature (5) can be applied against a magnet core (1). The electromagnetic valve further has a sleeve (12), which is held at the magnet core (1) and in which the armature (5) is guided such that it is axially movable, and a magnet coil (4) which surrounds the periphery of the sleeve (12) and can close or open the pressure medium connection between at least one pressure medium inlet duct (14) and a pressure medium outlet duct (15) in the valve housing (2) by means of the switching position of the valve closure member (11). Disposed between the armature (5) and the sleeve (12) in the valve housing (2) is an axially movable diaphragm piston (17) which has a clearance which is less than the clearance between the armature (5) and the sleeve (12).
