Milking system vacuum regulator - has valve body loaded by adjustable compression spring which is partly housed in weight recess

摘要

The vacuum regulation valve for milking systems has an inlet channel for the atmospheric air, a channel for connecting to a vacuum tank and a weight-loaded valve body. The vacuum regulation valve has a manually operated mechanism for the infinite adjustment of the air inlet resistance. The valve body (11) of the vacuum regulation valve is loaded by a weight (15) and by compression spring (30). The weight and the compression spring ar arranged one behind the other on the axis of rotation of the valve body. The compression spring (3) is partly housed in a blind hole (31) of the weight (15).
