ABSTRACT:
A poppet valve apparatus is structured to reduce the rate of build-up of fluid-borne debris within its internal architecture. The inlet and outlet ports are arranged tangential to the internal cylindrical walls defining the valve's flow chambers, whereby a circular flow pattern is produced within the valve interior, and a specially contoured flow director efficiently redirects the circular flow pattern through a circular annulus defined by a valve seat and a sealing ring.
