Patent ID: 8770089

Claim:
A crank-and-rocker piston machine, comprising a case accommodating a crankshaft with at least one crank which mounts, through a bearing, a slide block (slider), where the opposite work surfaces of the slide block interact with the surfaces of the link coupled with at least one piston reciprocating inside a cylinder secured to the machine case, characterized in that the piston and link are interconnected by a hinge assembly incorporating, as a minimum, a flat hinge, which enables the piston to self-align along the cylinder surface due to its travel relative to the link in any direction in the plane crossing the cylinder longitudinal axis, while the interfacing surfaces of the link and case taking up the reactive torque mount side support elements with contact surfaces and toothed racks and the space between the contact surfaces of the side support elements accommodate rollers provided with synchronizing toothed wheels which are engaged with the toothed racks of the side support elements, where at least two rollers are mounted on each side of the link, therewith the support elements and rollers are installed with preliminary constriction of interfacing contact surfaces and rollers.
