Embodiment Construction

[0043] In some embodiments, an apparatus is disclosed that includes a valve member designed to be reciprocatably disposed within a valve pocket formed by an interior surface of a cylinder head. The valve member has a tapered portion defining a plurality of flow paths with a plurality of sealing portions. The flow channel may for example extend through the tapered portion of the valve member with the flow channel having one or more openings formed by the outer surface of the tapered portion. At least one sealing portion is disposed proximate to each flow passage and is configured to contact a portion of the interior surface of the cylinder head such that each flow passage is positioned to maintain fluid flow isolation from an outer region of the cylinder head, wherein the outer region An example is the combustion cylinder of an internal combustion engine.

Abstract

An apparatus includes a valve member configured to be reciprocatably disposed within a valve pocket defined by an interior surface of a cylinder head. The valve member has a tapered portion defining multiple flow passages and including multiple sealing portions. At least one sealing portion is disposed adjacent each flow passage and is configured to contact a portion of the interior surface of the cylinder head such that each flow passage is configured to be fluidically isolated from an area outside of the cylinder head.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application No. 60 / 719,506, filed September 25, 2005; and U.S. Provisional Application No. 60 / 780,364, filed March 9, 2006, which are titled Both are "SIDE CAM OPEN PORTED ENGINES WITH IMPROVED CYLINDER HEAD VALVES," the entire contents of which applications are incorporated into this application as background. technical field [0003] The present invention relates generally to an apparatus for controlling the gas exchange process in a fluid handling machine, and more particularly to a valve-cylinder head assembly for an internal combustion engine. Background technique [0004] Many fluid handling machines - such as internal combustion engines, compressors, etc. - need to perform the gas exchange process precisely and efficiently to ensure optimum performance. For example, during the intake stroke of an internal combustion engine, predetermined amounts of air and f...
