摘要： A pneumatically actuated valve assembly for use as intake and/or exhaust valves on two- or four-stroke internal combustion engines. The assembly includes a valve (100), valve housing (200), and compressed gas distribution and timing mechanisms (Figures 5-8). The valve (100) is comprised of a short light weight hollow cylindrical body with a capped lower end and an opened upper end. The valve is further defined by a plurality of ports (104) adjacent to the lower end and a collar (198) encircling the body adjacent the upper end. The valve housing (200) is hollow and tubular having a larger diameter upper section and a smaller diameter lower section in which the valve (100) slides up to close and down to open. The housing (200) further includes hollow channels which direct compressed gas, managed by the distribution and timing mechanism, alternately towards the areas above and below the valve collar at regular intervals to open and close the valve, respectively.

摘要： A fast-action direct-fluid (gas or liquid) actuated valve assembly including a valve housing having an internal fluid port defined by a larger chamber and a smaller chamber, separated by a shoulder, a valve body seated in the valve housing and defined by a plurality of ports evenly spaced circumferentially around its circumference adjacent to an endplate seatable in the housing, a plurality of supporting wall sections (mullions) between the ports, and a plurality of internal vanes 9 each running along a corresponding mullion providing reinforcement thereof. The vanes 9 are inclined and/or curved, and defined by rounded faces to promote a smooth circular internal fluid flow. A valve cap formed with an annular collar is affixed to the valve body, and the valve body 2 and cap/collar 7 are slidably carried in the valve housing 1 between an open position and a closed position. A toolset is also disclosed for easily installing and removing the valve assembly.
