Patent ID: 7367355

Claim:
Twin manifold seat valve, including at least two closure members (S 1 , S 2 , S 3 ) each being structurally associated with at least one valve seat (D 1 , D 2 , D 3 , D 4 ), a single common solenoid (M) functionally associated with said at least two closure members, two reduction levers (U 1 , U 2 ) each being supported in a pivot support ( 11 ), said reduction levers (U 1 , U 2 ) 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 (S 1 , S 2 , S 3 ) are positioned relative to said pivot support ( 11 ) of the reduction levers (U 1 , U 2 ) such that said at least two closure members (S 1 , S 2 , S 3 ) move at the same time in the same direction of movement as said two reduction levers (U 1 , U 2 ) 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 (C 1 , C 2 ) is integrated into at least one of the two reduction levers (U 1 , U 2 ), and wherein said spring member (C 1 , C 2 ) 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.
