<p>The pressure converter has at least one pneumatic cylinder region, containing a pneumatic piston with an attached piston rod (32) and at least one hydraulic cylinder region, with a high pressure zone containing a hydraulic piston with an attached piston rod. The high pressure zone has high pressure axial seals (74,84,94) at its axial assembly joints (71,81,91), with fluid displacement in the high pressure zone during the working stroke of the piston rod of the pneumatic piston, a low pressure radial seal element (78,88,98) provided for each radial assembly joint (75,85,95) following an axial assembly joint in the oil leakage direction.</p> |
