Abstract:
1. A crank-and-rocker piston machine comprising a housing accommodating a crankshaft with at least one crank mounting, through a bearing, a slide block, its opposite work surfaces interacting with the respective work surfaces located on the rocker parts being opposite relative to the crankpin bearing rotation axis, where the rocker is linked to at least one piston reciprocating inside a cylinder secured to the machine housing, while the machine is provided with lateral support elements with contact surfaces which translate to the housing the reactive torque, where the interacting work surfaces of the slide block and rocker bear operating support elements with contact surfaces and toothed racks, where the space between the contact surfaces of the operating support elements of the slide block and rocker accommodates support rollers provided with synchronizing toothed wheels which are engaged with the racks of the operating support elements of both the rocker and slide block, where the opposite parts of the rocker which surfaces bear the operating support elements are interconnected by means of longitudinal connecting elements, the length of the contact surface of the slide block support element being equal to the length of the contact surface of the rocker support element and the length of the contact surface to be determined as a distance in the slide block motion plane between the extreme points of the surface area translating the force action in the slide block-rocker couple, incorporating a rocker which differs in that the piston and rocker are interconnected by means of a hinge assembly, accommodating at least a flat hinge, to allow the piston self-alignment along cylinder surface due to travel in any direction relative to the rocker in the plane crossing the cylinder longitudinal axis; lateral support elements mounted to interacting parts of the housing and rocker, crankpin bearing providing for angular travel of the slide block in the plane crossing the shaft rotational axis and for slide block travel along the shaft rotational axis to allow self-alignment of the slide block relative to the crank, where the coupling between opposite parts of the rocker and connecting elements is made so as to limit travel of one rocker part relative to its opposite part towards the direction opposite to the shaft rotational axis and along the rocker reciprocation to ensure the desired distance between the contact surfaces of the rocker operating support elements during the machine operation, while making the contact surfaces of operating support elements and rollers preloaded.
