A twin manifold seat valve comprising at least two closure members S1, S2, S3 each functionally associated with at least one valve seat D1, D2, D3, D4. At least one of the closure members is moved to a blocking position with predetermined blocking force at the valve seat upon energization of a solenoid and counter to the force of a spring 22, 7. A single common solenoid M is functionally associated to both closure members S1, S2, S3 by two pivotably supported reduction levers U1, U2. The armature 2 of the solenoid actuates both reduction levers U1, U2. The closure members are located on the same side of the pivot support of the reduction levers. A spring member is integrated into at least one of the reduction levers. The solenoid armature deforms the spring members to generate the closure member blocking force by moving the closure members into contact with their respective seats.

The invention claimed is: 1. Twin manifold seat valve, including at least two closure members (S1, S2, S3) each being structurally associated with at least one valve seat (D1, D2, D3, D4), a single common solenoid (M) functionally associated with said at least two closure members, two reduction levers (U1, U2) each being supported in a pivot support (11), said reduction levers (U1, U2) being functionally provided between an armature (2) of the solenoid (M) and said at least two closure members, each closure member being loaded by the force of a spring (7, 22) to act in a direction against the respective reduction lever, each of said at least two closure members being moved in energized condition of the solenoid by a respective reduction lever from a first predetermined position relative to its said valve seat into a second predetermined position in mechanical engagement with its said valve seat, wherein said at least two closure members (S1, S2, S3) are positioned relative to said pivot support (11) of the reduction levers (U1, U2) such that said at least two closure members (S1, S2, S3) move at the same time in the same direction of movement as said two reduction levers (U1, U2) are moved, wherein upon energization of the solenoid (M) at least one of the at least two closure members is brought by a respective reduction lever into the second predetermined position and held with a predetermined blocking force at its seat, wherein a spring member (C1, C2) is integrated into at least one of the two reduction levers (U1, U2), and wherein said spring member (C1, C2) in said energized condition of said solenoid (M) and in said predetermined second position of said at least one of the two closure members is deformed by said solenoid force and generates the predetermined closure member blocking force for its closure member. 2. Twin manifold seat valve according to claim 1, wherein a separate spring member (C1, C2) is functionally integrated in each reduction lever (U1, U2). 3. Twin manifold seat valve according to claim 1, wherein the spring member (C1, C2) is integrated into the reduction lever (U1, U2) between an armature actuation end (9, 9') and a closure member actuating end (10, 10') of the reduction lever. 4. Twin manifold seat valve according to claim 1, wherein both reduction levers (U1, U2) form a twin reduction lever having a single armature actuation end and two closure member actuating ends. 5. Twin manifold seat valve according to claim 3, wherein the armature actuation end (9, 9') abuts at a roller (18) supported at the armature (2). 6. Twin manifold seat valve according to claim 1, wherein the at least two closure members (S1, S2, S3) are actuated by rams (13, 17) which carry sliding caps (14) for abutment of the reduction levers (U1, U2). 7. Twin manifold seat valve according to claim 3, wherein the reduction lever (U1, U2) is of L-shape and has a larger cross-section in a region of the pivot support (11) and of the closure member actuating end (10, 10') than in a further lever portion extending between the closure member actuating end (10, 10') and the armature actuation end (9, 9'), the spring member (C1, C2) being a bending spring integrated into the further lever portion.
