Hydraulic pressure regulator for controlling an adjustable hydraulic displacement unit.

摘要

The present invention relates to a hydraulic pressure regulator (20) for controlling an adjustable hydraulic displacement unit consisting of a front and main stage (20a, 20b), wherein the controllable by means of mechanical or electrical primary reactor precursor two terminals (22, 23), the fluidsche Connection by means of a pilot piston (21) of the precursor (20a) is controllable, wherein the pilot piston (21) by a stepped bush (30) is surrounded and the installation orientation of the pilot piston (21) and stepped bushing (30) formed component combination is changeable such so that the pressure regulator can be operated optionally with a rising or falling characteristic curve.
