초록 ▼

An electromagnetic valve for handling fluid media has a valve mechanism which includes at least one valve seat and a valve-closing member which cooperates with the valve seat or seats. The motion of the valve-closing member is controlled by linkage that is connected to the moving arm of an electromagnet, while a return spring urges the armature in the direction opposite to the magnetic force. In order to permit the seating of the armature against a stop at the limit of its energized travel, while exerting a calibrated force on the valve seat, the armature is permitted to travel beyond the point at which the valve-closing member is arrested. The additional motion of the armature takes place against the force of an auxiliary spring which compresses during that part of the motion. When the coil is de-energized, the auxiliary spring urges the armature back into direct contact with the linkage, whereafter the motion transfer is loss-free.

대표청구항 ▼

A direct-acting magnetic valve for fluid media comprising an actuating unit, a magnetic actuating system including an armature connected to said actuating unit, said armature being movable in one direction by magnetic force and a primary return spring for moving said armature in the opposite direction, a valve unit having a housing connected to said actuating unit, said valve unit including at least one valve seat and a movable valve closing member disposed within said housing, means for transmitting the motion of said armature to said closing member for closing engagement with said at least one valve seat, a secondary spring disposed between said armature and said motion transmitting means concentrically with said primary return spring, said secondary spring being adapted to permit an additional movement of said armature by said magnetic actuating system with lost motion upon the termination of the action of said motion transmitting means into a final position relative to said motion transmitting means, said secondary spring exerting a compression force in the opposite direction of movement of said armature after the return of said armature from said additional movement caused by said lost motion between said armature and said motion transmitting means, said motion transmitting means including a rod having one end connected to said movable valve closing member and pivot means for connecting the other end of said rod to said armature with said rod being disposed in substantially vertically extending relationship with respect to the axis of said armature, said motion transmitting means including a drawing pin, means for supporting said pin for transverse play, said armature being continuously urged in said opposite direction by said primary return spring, said secondary spring comprising a compression spring disposed between said pin and said armature, said armature being provided with an axially disposed hollow space forming a shoulder at one end, said motion transmitting means including a pivotal joint, said pin being disposed centrally in said armature hollow space, said pin supporting means including said pivotal joint, one end of said pin including a nut said compression spring being disposed between said pin with one end in engagement with said nut and said shoulder and said return spring being disposed in surrounding relationship with said compression spring within said hollow space with one end in contact with said shoulder and the other end in contact with said housing.
