A hydraulic aggregate has at least one displacing machine having a driving mechanism, a driving/driven shaft, and a compensating coupling connecting the driving/driven shaft with the driving mechanism, and at least one machine unit connected with the driving/driven shaft of the displacement machine through a component, the compensating coupling between the driving mechanism and the driving/driven shaft of the displacement machine compensating a radial and an axial offset between the displacing machine and the machine unit.

A gear positive displacement machine has a housing, two gear members, and two bearing members supporting the latter. A gap is formed between an inner wall of the housing and a respective one of the bearing member, the gap increasing in two opposite axial directions. It may start from a central transverse plane of the bearing member. The gap may be formed by a convex peripheral surface of the bearing member or by a convex inner wall of the housing.

A gear positive displacement machine has two meshing gear members each having two axially opposite shafts, two pairs of bearing members each of which pairs bears one shaft of both gear members, at least one sealing member at one axial end of the gear members, and a supporting element reinforcing this sealing member. The supporting element has a U-shaped cross-section with two arms and a bead at a free end of each arm. The sealing member is inserted by its base side in the supporting member, and the beads of the arms of the latter engage in two grooves formed in the supporting member.
