FIELD: engines and pumps. ^ SUBSTANCE: at least two elastic elements are used in device, and they are located in recesses of piston body and actuate fixators, the opposite side of which is permanent contact with orifice body, transmitting effort from the side of elastic element. Fixators are distributed evenly along orifice circumferentially, and flat faces or grooves are arranged in places of contact on orifice body for orifice fixation in one of two positions: either being pressed to shelf or in suspended condition. Elastic elements may be arranged in the form of plates, and fixators - in the form of spherical bodies. Collars may be installed in recesses to prevent fallout of fixators from recesses, at that flat faces or grooves that fix orifice in different positions have different depth, and piston skirt has taper with reduction of diameter to the side of discharge chamber. ^ EFFECT: reduction of dimensions and weight of autonomous piston and higher efficiency of binary internal combustion engine operation. |
