ABSTRACT:
An axial piston machine has a housing with a cover, a swash plate located within the housing and an elongated rotary shaft extending through the swash plate and the housing with an end in the housing cover. A cylindrical drum is connected to the shaft for rotation therewith and one end of the cylindrical drum abuts against a surface of a control member located in the housing adjacent to the housing cover. A number of concentrically arranged cylindrical passages are formed in the cylindrical drum and a longitudinally moveable hollow piston is located in each cylindrical passage. A slide shoe is located at one end of each piston and each slide shoe is in working connection with the swash plate. Each slide shoe has a slide shoe plate, a slide shoe neck and a slide shoe head connected to one of the pistons. The face of each slide shoe plate which is opposed to the swash plate is in contact with an annular, spring-loaded retaining plate which is provided with a number of concentrically arranged recesses. The number and spacing of the recesses correspond with the number and spacing of the cylindrical passages in the cylindrical drum in order to receive the slide shoe neck. The faces of the slide shoe plates which face the swash plate are supported on an annular sliding disk which is connected to the annular sliding disk and the retaining plate in order to rotate along with the annular sliding disk and the retaining plate.
