摘要： A wobble yoke mechanism for converting reciprocating motion to rotary motion (or vice versa) in which each of two yokes (4) are connected to beams (3) by bearings (10, 10, 15, 15') having only one degree of freedom. The two yokes are 90° out of phase. An eccentric bearing (15), also having only one degree of freedom, is fitted to or about the nutating shaft (16) and is connected to one end of each of the yokes (3). All the axes of the pairs of bearings pass through a central pivot point (5). The axes of the pistons need not be straight nor need they be parallel with the axis of the crankshaft (12).

摘要： The invention concerns a device for transforming a rotational movement of a shaft (8) rotating about an axis of rotation (9), into a reciprocating rectilinear movement of a mobile part along a direction substantially parallel to said axis or inversely, comprising an oscillating plate (25) with axis (14) inclined relative to the axis (9) of the shaft (3), the intersection of said axes (9, 14) defining a instantaneous center of rotation O of the oscillating tray. The device is further provided with at least one spindle-forming shaft (27) extending substantially perpendicular relative to said axis (14), an axis of said spindle passing substantially through the instantaneous center of rotation O of the oscillating plate, and a linking element extending substantially perpendicular relative to the axis of the spindle and relative to the axes (9, 19) of rotation of the shaft and of translation of the mobile part, said linking element co-operating with the spindle and being designed to be mounted on the mobile part.

摘要： A variable compression piston assembly (300) includes a plurality of pistons, e.g., double ended pistons (330, 332), a rotating member, e.g., a flywheel (322) or a zero-stroke pivot member, coupled to the transition arm (310) and configured for movement relative to the transition arm (310) along the axis of rotation of the rotating member (322). The movement of the rotating member (322) relative to the transition arm (310) changes the compression ratio of the piston assembly (330, 332). The transition arm (310) is coupled to each of the double ended pistons (330, 332) at approximately a center of each piston (330, 332). The movement of the rotating member (322) relative to the transition arm (310) changes the compression ratio and displacement of each double ended piston (330, 332).
