A variable-stroke crank mechanism includes a crankshaft rotatably mounted in a casing and having an eccentric crankpin, and a plurality of fluid pressure actuators disposed substantially radially with respect to the crankshaft, for pressing the eccentric crankpin to rotate the main shaft and the casing relatively to each other. The fluid pressure actuators are selectively supplied with a working fluid. An eccentric collar is rotatably mounted on the crankpin and operatively coupled to the fluid pressure actuators. The eccentric collar having an axis which is eccentrically displaced with respect to the axis of the crankpin. The crankpin and the eccentric collar are arrested in their respective angular positions by intermeshing internal and external gears. The crank mechanism may be incorporated in a plunger-type hydraulic unit, which may also be incorporated in a hydromechanical continuously variable transmission.
