HYDROPNEUMATIC PISTON ACCUMULATOR

A hydropneumatic piston accumulator has an accumulator housing (1) defining a housing longitudinal axis (11) and a piston (9) longitudinally movable between two housing covers (5, 7) positioned opposite each other. In the housing (1), the piston (9) separates a working chamber (13) for a compressibl...

More Information
Summary:A hydropneumatic piston accumulator has an accumulator housing (1) defining a housing longitudinal axis (11) and a piston (9) longitudinally movable between two housing covers (5, 7) positioned opposite each other. In the housing (1), the piston (9) separates a working chamber (13) for a compressible medium, such as a working gas, from a working chamber (15) for an incompressible medium, such as hydraulic fluid. A piston part (55) of a displacement measurement device continuously determines each position of the piston (9) in the housing (1). A rod-shaped guide (29, 57) is stationarily positioned in the accumulator housing (1) and passes all the way through the piston (9) in each of its displacement positions in the accumulator housing (1). The piston (9) is movably guided along the guide until it reaches the stop on one of the two housing covers (5, 7) and is sealed against this guide (29,57) using a sealing device (49, 50).
