A stirling cycle engine, especially for refrigerating motors, comprising a housing in which are assembled a rotating shaft, at least three working cylinders arranged in parallel round the shaft, a double-acting piston in each of the cylinders, and a mechanical transmission converting the reciprocating movement of the pistons into a rotary movement of the shaft. The housing has a first chamber (1) in which the rotating shaft is assembled, and a second chamber (2) in whch the mechanical transmission is assembled. The latter consists of an orbiting oscillating plate (13, 14) immobile in rotating and having an axis which describes a conical surface about the rotating shaft, and of articulated connections linking each piston (4) to the oscillating plate. An elastic gasket (18, 19) between the housing (11) and the oscillating plate (13, 14) prevents communication between the first and second chambers (1, 2), and each articulated connection (15, 22) is assembled in a receptacle (3) of a component connected rigidly to the piston (4), the space in the receptacle (3) being isolated from the second chamber (2) by elastic gaskets (23). |
