AXIAL PISTON MACHINE CONNECTION ROD ASSEMBLIES

摘要

A connection mechanism between a recipricator and a piston of a Z-crank engine or pump. The engine or pump includes a crankshaft having a crankshaft axis and carrying an angled crank about which the recipricator can rotate. The connection mechanism comprises a connection rod extending between the piston and the recipricator and that is connected to the recipricator by a big end joint has two rotational degrees of freedom defined by two pivot axes, a first (the big end joint to connection rod pivot axis)intersects the angled crank axis and a second (the big end joint to recipricator axis) is tangential to the axis of the angled crank.
