    摘要： A reciprocating piston mechanism comprises a crankcase and a crankshaft having at least a crankpin The crankshaft is rotatable about a crankshaft axis. The mechanism comprises a crank member which is rotatably mounted on the crankpin, and comprises at least a bearing portion which is eccentrically disposed with respect to the crankpin. The bearing portion has an outer circumferential wall which bears the big end of a connecting rod such that the connecting rod is rotatably mounted on the bearing portion of the crank member via the big end. The crank member is provided with a crank member gear which meshes with a first auxiliary gear being an external gear. The first auxiliary gear is fixed to a second auxiliary gear via a common auxiliary shaft The auxiliary shaft is mounted to the crankshaft and rotatable with respect thereto about an auxiliary shaft axis which extends parallel to the crankshaft axis. The second auxiliary gear meshes with a central gear having a centre line which coincides with the crankshaft axis. The crank member gear is an internal gear.

    摘要： This invention relates to a mechanism and method for enhancing the performance of both two stroke and four stroke cycle reciprocating piston internal combustion engines, reciprocating piston pumps and compressors by generating an Epitrochoidal path of travel for the lower end of the connecting rod. The piston, attached to the upper end of the connecting rod, will be made to dwell at the lower part of its travel, enhancing the output of the engine, pump or compressor through better utilization of the available cylinder pressure.

    摘要： A yoke type engine wherein the orbital path of the slider is alterable to effect piston stroke and compression ratio changes. A crank component has a crankpin which carries and positions the slider. A boss of the crank component is carried by a control shaft in an offset manner. Timing gears normally drive the control shaft in synchronization with the crankshaft to maintain a constant stroke and compression ratio. Relocation of certain timing gears by an actuator causes the control shaft to rotationally advance or retard to reposition the crank component carried thereby to in turn alter the orbital path of the coaxial crankpin and slider relative to a crankshaft axis. Accordingly, high and low compression orbits for the slider may be effected to best suit engine loads. A variable length throw couples the slider to the crankshaft. The orbital path of the slider provides increased crankshaft leverage over conventional engine arrangements.

    摘要翻译： 轭式发动机，其中滑块的轨道可改变以实现活塞行程和压缩比变化。 曲柄部件具有支承并定位滑块的曲柄销。 曲柄部件的凸台以偏移的方式由控制轴承载。 正时齿轮通常与曲轴同步地驱动控制轴，以保持恒定的行程和压缩比。 通过致动器对某些定时齿轮的重新定位使得控制轴旋转地前进或延迟以重新定位由此承载的曲柄部件，从而改变同轴曲柄销和滑块相对于曲轴轴线的轨道路径。 因此，可以实现用于滑块的高和低压缩轨道以最好地适合发动机负载。 可变长度的投掷将滑块与曲轴相连。 滑块的轨道路径提供了比常规发动机装置更高的曲柄轴杠。
