Electromagnetically-actuated 2/2-way valve, for hydraulic motor vehicle brake systems having an anti-skid and traction control apparatus

An electromagnetically-actuated multiposition 2/2-way shutoff valve (15), for hydraulic motor vehicle brake systems having an anti-skid and traction control apparatus, having a housing (33), a longitudinal bore (35) in said housing (33), an armature (36) and a first-closing body (46) carried by said armature and movable toward a first valve seat (59), a second closing body (47), said second closing body having said first valve seat (59) thereon for receiving said first closing body thereon, said armature moves said first closing body toward said first valve seat (59) counter to the force of a restoring first spring (43), a wall (42) juxtaposed said first closing body firmly attached within the longitudinal bore (35) to the housing (33), the wall having a through bore (54) through which a portion of said second closing body extends, said through bore like the longitudinal bore (35) communicates with a fluid flow connection upstream of said wall (42) and a flow connection downstream of said wall (42), the wall (42), on a side remote from the first closing body (46) includes a second valve seat (55) through which the through bore (54) discharges;

• said second valve seat (55) is engaged by said second closing body (47) which includes an axially extending conduit (58) which extends from said first valve seat (59),
• the second closing body (47) is supported on the second valve seat (55) under the influence of a bearing force of a restoring second spring (49), and the biasing force of said second spring is greater than a force produced by the armature (36) to close said first closing body.
