  • Patent number: 11008862
    Abstract: A hydrostatic piston engine comprises a housing with a cylinder drum with cylinder bores mounted rotatably therein. Each of the cylinder bores receives a working piston in a longitudinally displaceable manner, via which a hydrostatic working chamber is delimited by the cylinder bore. The hydrostatic working chamber has an opening on an outer surface of the cylinder drum by which, when the cylinder drum rotates, outlets of a high-pressure chamber and of a low-pressure chamber of the piston engine and a reversing surface arranged between the two outlets in the rotational direction can be passed over in alternating fashion. At least one pressurizing medium channel is provided which, on one hand, opens out in the reversing surface and, on the other, into a pressurizing medium trough of the piston engine.

  • Patent number: 8231359
    Abstract: A pump unit includes a main pump (4) and a charge pump (5), the pump capacity of which is adjustable via an adjusting element. To adjust the pump capacity of the charge pump (5), an adjusting element of the charge pump (5) is acted upon by an adjusting force which is dependent on the inlet pressure of the main pump (4).

  • Patent number: 7084727
    Abstract: The aim of the invention is to provide a switching device (1) based on a uniform control tile, which is easy to produce and assemble, ensuring good electric insulation properties. To achieve this, the device comprises an adapter (12) with second contact means (13), arranged to form a connection between first contact means (7, 8) and a conductor (10) that is to be connected. Said adapter and second contact means have insulating isolating elements (18, 18a, 18b, 18c), at least bordering several sides, for defined creepage distances and clearances.
