    专利说明:

    The invention relates to mechanical engineering and can be used to create piston volumetric machines, in particular Stirling engines.
    The aim of the invention is to increase the efficiency of the machine by making the pistons axially rotating.
    FIG. 1 is a schematic diagram of a Stirling engine; in fig. 2 is a diagram of a piston-actuator of FIG. 3 - the same, bottom view; in fig. 4 - working piston, top view
    The Stirling engine contains at least one cylinder 1, the pistons accommodated therein with the possibility of reciprocating motion, the first of which, the piston propellant 2, has at its ends a series of tangentially directed grooves 3, formed turbine surfaces, and separates the volume of the cylinder on the expansion cavity 4 and compression 5, and the second, working piston 6, the end of which has a number of tangentially directed grooves 7 forming the turbine surfaces, and limits the compression cavity 5 and the main 8, including the heater 9, reg generator of 10 and the cooler 11 and connecting the cavity
    4 and 5 through tangentially made in the wall of the cylinder 1 window 12, placed in the zones of the ends of the stroke of the piston - displacer.
    The engine is operated by forcing the working heat of the piston propellant 2 to the expansion cavity 4, then to the cavity
    5Press through the heater 9, the regenerator 10 and cool (eh 11. When the main mass of the working heat is concentrated in the heater 9 and the expansion cavity 4, its pressure and temperature increase, the engine is in operation when the main mass of the working heat is concentrated in the cooler 11 and the compression cavity 5 its pressure and temperature drop — a compression stroke is performed.
    The hydrodynamic lubrication of the Stirling engine pistons is accomplished by supplying part of the working heat into the gap between cylinder 1 and pistons 2 and 6. Working heat leaves windows 12 tangentially and impacts tangentially nationalized grooves 3 and 7, made on pistons x 2 and 6 , while finding the pistons in their Kpai innx

    points. The grooves 3 and 7 form turbine surfaces, and when a working heat jet strikes the pistons, a torque is generated, the pistons move not only reciprocating, but also begin to rotate around their own axis, thereby creating a more favorable condition. for its separation from the inner wall of CylP1.
    The tangential grooves 3 and 7 on the pistons x 2 and 5 can be angled towards each other with their angles, and the pistons are given a versatile direction.
