Abstract
The non-return valve comprises a cup-shaped throttling disc (1) of elastic material, mounted on a perforated support plate (2). The external diameter of the elastic disc is equal to or greater than that of a stepped circular seat rim (3) adjacent to the plate The elastic disc allows easy flow in the one direction, and does not creste a shock-load on closing when it flattens out against the plate. No notice is generated on closing. When it provides an immediate and tight seal. Little pressure is required for opening, and the disc is very cheap.
