Hydrostatic positive-displacement machine i.e. axial piston machine, for use as hydraulic motor integrated pump for e.g. internal combustion engine, has pressure sequence valve making supply of positioning device with pressure medium

摘要

The machine (2) has a rear pivot device (40) making an application of the machine towards reduction of a restrictor volume during drop of supply pressure of supply pressure sources (11). The rear pivot device comprises a pressure sequence valve (41), which is connected with a working group of the machine at an input side. The pressure sequence valve makes a supply of a positioning device (6) of the machine with pressure medium from the working group during drop of the supply pressure of the supply pressure sources below a border pressure.
