Abstract

See full text

A compact and light-weight hydraulic accumulator configuration for a hydraulic brake includes a high-pressure storage chamber, a medium-pressure storage chamber and an atmospheric-pressure storage chamber. The high-pressure storage chamber, the medium-pressure storage chamber and the atmospheric-pressure storage chamber are disposed in a common housing which delimits the high-pressure storage chamber along with a high-pressure piston movably guided within the housing while delimiting the medium-pressure storage chamber along with a medium-pressure piston movably guided within the housing. A high-pressure spring located in the housing rests on the high-pressure piston outside the high-pressure storage chamber and a medium-pressure spring located in the housing rests on the medium-pressure piston outside the medium-pressure storage chamber.
