ABSTRACT:
A double admitting pressure intensifier which automatically reverses at its end positions is provided. The pressure intensifier comprises a pressure intensifier piston and a control slider running parallel to the pressure intensifier piston, each disposed in a bore of a casing. The control slider receives a control impulse only at the end of a stroke in order to maintain the pressure intensifier trouble-free under all conditions. This is assured by disposing two pressure pins of different diameter projection into axial bores of the control slider. The pressure pin with the larger diameter is connected to the feed line or, respectively, to the discharge port depending on the position of the pressure intensifier piston. The pressure pin with the smaller diameter is, on the other hand, continuously connected with the feed line.
