Abstract
A plate valve comprises a domed resilient catcher plate positioned above a valve seat to limit the stroke of a valve closure plate controlling fluid flow through passages in the valve seat. The catcher plate has its concave surface facing the valve seat and is held in position only in the region of the valve axis, the outer edge of the catcher plate being free.
Claims6
A plate valve, comprising:
- a valve seat including passage means;
- a flexible closure plate for controlling the flow of a fluid through said passage means;
- a resilient catcher plate for limiting the opening stroke of said closure plate, said catcher plate is in the form of a domed spring with the concave surface thereof facing said valve seat for biasing said closure plate to close said passage means, said catcher plate being mounted at its central portion only along a central axis of said plate valve and extending in spaced relation over said valve seat;
- and
- whereby said flexible closure plate and said resilient catcher plate provide dampening for the initial opening of said passage means and the elastic deformation of said catcher plate provides an initial closing force for said closure plate.
