Abstract
In a hydraulic piston machine where the piston 20 or the pistons perform a longitudinal, arcuate movement relative to the cylinder 3 or the cylinders, the packing arrangement for the piston 20 consists of a packing ring 24 in the form of an annular body of an elastomeric material. This packing ring 24 is placed in a circumferential groove 25 in the associated piston 20. The side of the groove facing away from the pressure side of the piston 20 is constituted by a supporting ring 29, the outer side of which just having clearance relative to the cylinder wall. The supporting ring 29 is carried radially displaceable in a groove 37 to the side of the packing 24, and the latter has an outer diameter in its unloaded state being greater than the cylinder bore. The soft packing gives a large sealing surface and thereby a small specific sealing pressure, and is prevented by the supporting ring 29 from being crushed. <IMAGE>
