摘要： An internal combustion engine may include at least one cylinder and at least one hollow-heat valve. The at least one hollow-head valve may include a valve shaft and a valve head, and may be guided in a valve shaft guide. The engine may also include at least one valve seat ring on which the valve head sealingly lies when the at least one hollow-head valve is closed. The engine may additionally include a valve shaft seal with at least two seal lips and oil disposed between the valve shaft and the valve shaft guide. The at least one valve seat ring may be composed of a sintered metal including infiltrated copper. The valve shaft may include one of a chromium-containing coating and a boron carbide-containing coating.

摘要： A linear fluid piston device not requiring a fluid valve to operate and has operating piston stroke capabilities beyond traditional vibration fluid devices. The linear fluid device features (a) a movable piston means for linear motion, (b) a feature wherein said body provides rotational movement for fluid port alignment and a pressure vessel containing an (c) end cap and (d) cavity sized to guide the movable piston. In the improvement, the moveable piston provides a method for changing the linear direction in the event the total linear piston movement has not completed.
