Patent ID: 8820348

Claim:
A valve to control the intake and outlet of gases or liquids for reciprocating compressors and pumps comprising: a radially oscillating valve member moving in a rotational direction between a closed position and an open position; a valve cover including a plurality of spring adjusting holes; an external spring having a spring force and biasing said valve member towards said closed position, whereby said spring force is changed by selecting one of said spring adjusting holes at a top of said valve cover; a static cylinder including a plurality of radially positioned flow ports and a plurality of radially placed straight strips that block or allow a compressed media to flow through said flow ports; one or more stop surfaces per strip that are fixed to limit an angular movement of said strips, and the external spring biasing said strips towards a seating surface; as an internal gas pressure of said compressed media develops a load that exceeds said spring force, said valve member rotates in said static cylinder towards an oscillation stop to said open position, and allows said compressed media to flow through said flow ports; a developed energy in said spring returns said valve member to said closed position.
