Abstract
In packings for hydraulic pistons or piston rods with a packing ring 1 of a tough elastic synthetic material as the contact packing between a stationary machine part comprising an annular groove 3 and a moving machine part comprising an initial slope 11, and with a rubber-elastic clamping ring 2 clamping the packing ring radially and providing a sealing action with respect to the annular groove 3 in the stationary machine part 4, the packing ring 1 has an annular surface 7 located between the end face of a step at the high pressure side and a conical surface adjoining the latter on the low pressure side, which annular surface forms an obtuse angle x with the conical surface 6 of such a value that when the packing travels in over the initial slope 11, the resultant Fres of the normal force FN and of the frictional force FR halves the sealing edge angle x. When using conventional materials and conventional angles for the conical surface and the inlet slope, a value of 45 degrees is provided for the angle between the annular surface 7 and the packing axis. The axial length of the annular surface 7 preferably amounts to 5% of the axial length of the packing ring 1. <IMAGE>
