Abstract
The hydraulic motor has a cylinder with a stepped reciprocating piston with relatively proportional front and rear faces which form a first, second and intermediate zone together with axial faces and the cylinder walls. The intermediate zone is sealed w.r.t. the first zone. A valve-controlled inlet and outlet on the cylinder are connected with the intermediate zone. The cylinder wall regions form a cylindrical recess, opening into the second zone, and passages, in order to create a connection between the recess and the second and intermediate zones. A tubular flush valve rod has orifices near one end and a pair of axially spaced flanges (68, 69) at its other end. These flanges slide in the cylindrical recess. A stop on the rod is arranged between the flanges and one rod end.
