Pressure drop compensation for fluid pressure circuit

摘要

Fluid pressure is generated in a circuit which is fed over a line to an operating element (20). The pressure drop compensating system is connected to the central region of this line. The compensation system consists of a piston which can move in a housing, an operating pressure in-feed chamber, which is mounted at one end of the housing and which feeds-in the operating pressure which moves the piston in the housing. The arrangement further consists of a fluid pressure generating chamber which is connected to the other side of the housing and which is connected via a branch line to the line which leads to the operating element. A non-return valve is mounted in the branch line which only allows flow from the pressure generating chamber to the feed-line.
