Abstract

The check valve assembly is formed by an annular disc (20) with a central bore (22), and which has a one-way valve (24). The one-way valve comprises a valve plate (28) covering the central bore in a first position and which inside a cage fastened to the annular disc is movable into a second position opening the central bore. Several guide rods (32,34) standing perpendicularly to the annular disc and spaced around the central bore provide stops to limit the travel of the valve plate in the second position.
