ABSTRACT:
A valve is provided primarily for medical or surgical aspiration equipment. The valve is interposed in an air line between the low pressure side of a pump and a collecting bottle for body fluid. The valve chamber has a sump-like bottom in which any liquid or froth entrained in air drawn in at a higher position will collect, and the valve member defines with said bottom narrow air admission apertures which are readily occluded by such liquid or froth, thereby producing a pressure difference across the valve member which displaces it to the valve-closed position.
