Abstract

A hydrostatic hybrid drive device (H) includes only one hydrostatic displacement machine (1) operated in an open circuit. A delivery line (2) leads to a high pressure accumulator device (3). A shutoff valve (5) controls flow to the high pressure accumulator device (3). A branch line (6) is connected with a low pressure accumulator device (7). A shutoff valve (9) in the intake line (8) shuts off flow to the low pressure accumulator device (7). A discharge line (10) is connected between the intake side (S) of the displacement machine (1) and the shutoff valve (9). A valve device (15) controls the discharge line (10) and the branch line (6).
