Definitions

  • the swash plate 20 of the invention has one or more of the following characteristics :
  • the envelope 7 is formed by two shells 7E1,7E2 which are attached together for forming inner chamber for receiving the tube elements, the pistons, the swash plates and the drive shaft, as well as for forming channels 7C for a cooling liquid, and channels for the passage of air into the combustion chambers or for the exhaust of combustion gases.
  • PP engines suffer from wear of the swash plate owing to the forces applied between the joints which translate the lateral movement of the pistons into rotational movement by the drive shaft. Improvements to the design of the swash plate by the present inventor have surprisingly lead to a better distribution of forces within the swash plate bearings, which improvements do not require more heavily engineered components, or more substantial bearings.
