Abstract

See full text

A reciprocator restraint assembly for a Z-crank axial piston machine is described. The assembly includes two gimbal arms each linked together at gimbal link joint that intersect at a point T. Point T lying in a medial plane M being defined as the plane passing through the point of coincidence of the crank and crankshaft axes to which the line that bisects the crank angle is normal. Each of the gimbal arms is pivotally mounted at an identical distance L from point T. A cylinder gimbal is pivotally mounted from the cylinder cluster and a reciprocator gimbal is pivotally mounted from the reciprocator. The reciprocator gimbal pivot axis is equidistant from point X and T as is the cylinder gimbal pivot axis. The orientations of the pivot axes of the two gimbal arms being mutual reflections in the medial plane M resulting in the point T lying on the medial plane M as the crankshaft rotates with respect to the cylinder cluster, and thus ensuring homo-kinetic rotational restraint between the reciprocator and the cylinder cluster.
