    摘要: A sleeve valve with a valve body that at least partially encircles at least one piston that moves in a reciprocating manner can, at least partially define with the at least one piston a combustion chamber of an internal combustion engine. A valve actuation mechanism can move the sleeve valve between an open position and a closed position to control flow through a port of the internal combustion engine. The sealing edge of the sleeve valve can be urged against a valve seat by an urging force generated by the valve actuation mechanism when the sleeve valve is moved to the closed position. At least one of the sleeve valve and the valve seat can include a valve assistance feature that assists the valve actuation mechanism in resisting forces generated by the internal combustion engine in opposition to the urging force. Related articles, systems, and methods are described.

    摘要: Various types of valve systems are disclosed herein. In one embodiment, a positive control reciprocating sleeve valve system for use with an internal combustion engine includes opening and closing rockers controlled by corresponding opening and closing cam lobes. In one aspect of this embodiment, interference can be designed into the valve control system to provide additional “hold-closed” force to hold the valve against its seat during a portion of the engine cycle. In another aspect of this embodiment, positive control valve systems can include compliant components and systems, hydraulic systems, pneumatic systems, and/or mechanical spring systems to control valve lash, facilitate sealing, etc.
