    摘要: The invention relates to a hydrostatic piston engine (1) which is based on the floating cup principle and comprises a first swash plate (16) and as well as a second swash plate (17). A first cylinder drum unit (11, 14) rests against the first swash plate while a second cylinder drum unit (12, 15) leans on the second swash plate (17). A first group of pistons (10) and a second group of pistons (12) are connected in a fixed manner to a drive shaft (5) of the hydrostatic piston engine (1). The first group of pistons (10) engages into the cylinder cavities of the first cylinder drum unit (11, 14) while the pistons (12) of the second group engage into cylinder cavities of the second cylinder drum unit (12, 15). The first and second cylinder chambers embodied by the pistons (10, 12) and the cylinder drum units (11, 14; 12, 15) can be connected to a first hydraulic circuit and a second hydraulic circuit, respectively. The axis of rotation of the first cylinder drum units (11, 14) and/or the axis of rotation of the second cylinder drum unit (12, 15) can be adjusted independently of the axis of rotation of the other cylinder drum unit.
