FIELD: machine building.SUBSTANCE: multipurpose valve contains body with input and output holes, secured in it membrane, creating with body above membrane chamber coupled with atmosphere, and stock chamber. The stock chamber is tightly separated by the partition from the above valve chamber created by part of body with output hole, and the above valve chamber borders with the under valve chamber created by part of body with output hole. The under valve and above valve chambers are connected with each other by the throttle hole and work hole with lock element. The stock and under valve chambers are connected by the channel. The lock element is rigidly connected with the membrane by means of the stock with possibility of the reciprocating movement via the tight hole in the specified partition.EFFECT: increased reliability of valve operation due to assurance of automatic opening and closing of the specified valve.2 dwg |
