在活塞式发动机内安装平直的汽缸轴2代替曲轴,可省掉难于加工的作业(苏联专利 a.c.1038487)。轴上没有费工的花键和各种沟槽等等。活塞3不动,由汽缸内腔与活塞和盖5的端面形成两个工作腔,通过两个工作腔的轮流动作使汽缸4作往复运动。轴的回转运动则由两个反相工作的超越离合器1传递。故在汽缸的每个行程内以脉冲式带轴转动。在汽缸运动的任意方向上,每个超越离合器都能依次与在一个方向上完成回 Installing a straight cylinder shaft 2 in a piston engine instead of a crankshaft eliminates the need for difficult-to-machine work (Soviet patent a.c.1038487). There are no spindles on the shaft and various grooves and so on. The piston 3 does not move, and two working chambers are formed by the cylinder cavity, the piston and the end surface of the cover 5, so that the cylinder 4 reciprocates through the rotation of the two working chambers. The rotary motion of the shaft is transmitted by two counter-rotating clutches 1 operating in opposite directions. Therefore, each stroke in the cylinder with a pulse with shaft rotation. In any direction of cylinder motion, each overrunning clutch can be completed in turn in one direction
