Abstract:
A magnet valve (10), comprising an armature (20) for actuating a valve closing body (40), a coil (24) for actuating the armature (20), a cup-shaped sleeve (46) in an interior of a hydraulic block (32) in which the valve closing body (40) is located and in a bottom (44) of said cup shaped sleeve a flow opening (50) having a valve seat (42) for the valve closing body (40) is mounted, and at least one further flow opening (58), disposed on the bottom (44) of the cup-shaped sleeve (46) laterally of the flow opening (50) for the armature-actuated valve closing body (40), a check valve (60, 56; 64, 70) having, a valve closing body (56; 64; 70) for closing the at least one further flow opening (58), the cup-shaped sleeve (46) is a shaped sheet-metal part made without metal-cutting machining, said bottom (44) has a plurality of said flow openings (58) for the check valve (60, 56; 64; 70) which are disposed along an imaginary circle around the flow opening (50) for the armature-actuated valve closing body (40), and that the valve closing body (56; 64; 70) of the check valve (56; 64; 70) is embodied in the form of an annular disk that extends along the bottom (44) on a side of the cup-shaped sleeve (46) remote from the armature-actuated valve closing body (40), and is retained by a component (59; 63) mounted on an outer circumference of the cup-shaped sleeve (46).
