Abstract: The present invention relates to a motor comprising at least one piston of linear and reciprocating translational movement and a swash plate mounted at an angle on a shaft driven in rotation in an engine block by the reciprocating movements of the plate which is in contact with the piston. Each piston is integral with a rod, the end of which opposite the piston includes a slide which moves in a guide in the engine block. Each slide holds two shells which form a seat for each swivel joint of the swash plate. Preferably, the swash plate includes two or four swivel joints.

Abstract: A power generator comprising: body means having three chambers separated from each other by fixed fluid-tight partitions and having a central bore. Shaft means are rotatably mounted in the central bore of the body means with at least one end of the shaft means extending from the body means. At least two drive cylinders are mounted in the central one of the chambers in the body means, each of the drive cylinders include two pistons which are slidably mounted in opposition with each piston having two opposite working faces. The piston rods are attached to the corresponding ones of the pistons traversing a respective of the partitions through stationary fluid-tight joints for allowing the piston rods to move therethrough on a pure translational movement. Two swash plate means are provided. Each of the swash plate means includes a respective lateral one of the chambers.
