20150267699 | Motor-Pump Unit - A motor pump unit with a multipart housing comprises a reversible internal gear machine and an electric motor with a rotor and a stator, which is coupled to the internal gear machine via a shaft rotatably mounted in the housing. One shaft end extends from the internal gear machine axially through the rotor that is carried by the shaft. First and second connecting channel ends in the working chamber of the internal gear machine are connected via check valves in the housing to a leakage channel loop, which is fluidically connected to a leakage channel that is fluidically connected to the working chamber, and which has a shaft leakage channel extending axially through the shaft and a rotor leakage channel that is fluidically connected thereto and extends axially through the rotor and/or a gap leakage channel between the rotor and stator, which is fluidically connected to the shaft leakage channel. | 09-24-2015 |
20150267701 | Motor-Pump Unit - A motor pump unit comprises an electric motor and a reversible internal gear machine. The latter has a multi-part housing in which an externally toothed pinion and an internally toothed hollow gear are arranged. A free space, in which a multi-part filler element is arranged, is configured between the gears. The filler element comprises radially movable sealing segments, between which a radial gap is configured. An axially movable sealing plate is arranged between axial faces of the gears and a housing part. This has a sealing plate control groove that is open to the faces of the gears and that can be pressurized, and which is open to the radial gap and located directly opposite thereto. The pinion segment and/or hollow gear segment has a radial sealing segment control channel that can be pressurized and extends transversely, is open to the radial gap, and ends directly in the radial gap. | 09-24-2015 |

20130056103 | VALVE ARRAY - A valve array includes a reservoir containing a pressurized fluid, a non-return valve and a seat valve that is actuatable so as to allow the fluid to flow out of the reservoir. The seat valve is configured as a pilot control valve connected to the reservoir such that, in an open condition of the seat valve, a smaller amount of the fluid flows out of the reservoir via the seat valve and a larger amount of the fluid flows out of the reservoir via the non-return valve. | 03-07-2013 |

20150144216 | PISTON ACCUMULATOR - A piston accumulator in which good sealing and guidance of a piston is ensured, even if the diameter of the housing undergoes expansion, the strength, weight and costs of the piston accumulator being optimised as far as possible, a piston accumulator, which has a housing defining a pressure chamber and receiving a movable piston, a compressible fluid being held in the pressure chamber, the piston having a housing side facing the pressure chamber and the piston having a working side which can face a working fluid that can move the piston with a bushing provided, within which the piston can move. | 05-28-2015 |
