Abstract:
A magnet valve (10) for insertion into a receiving bore (18) of a hydraulic block (20) of a slip-controlled hydraulic vehicle brake system,a base body (40) which has a through bore (44) and can be inserted into the receiving bore (18) of the hydraulic block (20),a valve dome (46), which is mounted on the base body (40) coaxially to the through bore (44) and in which an armature (48) is axially displaceably received and which is surrounded by a coil (12),a valve seat part (58) with a valve seat (54), which is inserted remote from the armature into the through bore (44) of the base body (40),an armature-actuated valve tappet (50) with a valve closing body (52) in the through bore (44), anda fluid-carrying connection between a chamber, in the through bore (44) toward the closing body, and the circumference of the magnet valve (10),the base body (40) is an extruded part;at least one longitudinal groove (62) extends in the wall of the through bore (44) of the base body (40), between the chamber toward the closing body of the through bore (44), along the valve seat part (58) to the face end of the base body (40) remote from the armature,at least one radial groove (64) extends at the face end, remote from the armature, of the base body (40) and leads to the circumference of the magnet valve (10),the longitudinal groove (62) and the radial groove (64) are in fluid-carrying communication.
