plattenventil grassroots based ventilplattenlenkern with off centre

摘要

In the valve-plate of a disc-valve, frictionless guides are arranged in a balanced configuration from web center to web center, each guide situated above and between the edges of an adjacent seat-plate ring segment, so that the valve-plate is balanced against shaking movement during operation and the guides experience a balanced, and small, mechanical stress. In practice, the seat-plate and the catch-plate are pre-stressed elastically and convexly toward one another, so that the net deformation of the seat-plate during closure operation is reduced.
