The disclosure relates to a pump assembly for a vehicle having an internal combustion engine with or without transmission or electric motor with transmission or for an oil supply having a double-pipe pump, wherein the two pipes are separated from each other and a second pipe can be connected to a first pipe, wherein the pump has at least one input drive point for an electric machine and also for a drive motor, including, for example, via a gearbox.

The present invention discloses a hydraulic style motor having a first power input housing containing a first plurality of rotary or centrifugally driven pumps and associated valves, such that the pumps are driven in a determined stacked fashion by a powered input (or drive) shaft. A second power output housing contains at least one second rotary driven pump and associated valve, the second pumps rotatably engaging a second output (driven) shaft. A pressure resistant fluid line interconnects a manifold associated with the first housing with another manifold associated with the second housing so that the pressurized fluid generated by rotation of the input pumps in the input housing is communicated to the output housing to drive the output pumps to rotate the output (driven) shaft. A return line communicates with the output housing manifold, via each of the individual pump and valve subassemblies, for redirecting flow back to an input feed to the input housing.

A transfer device that includes a case that houses a transfer mechanism; a strainer that suctions oil stored in a lower portion of the case; a valve body that has a hydraulic supply circuit that supplies a hydraulic pressure to the transfer mechanism and a suction oil path that discharges an extra hydraulic pressure that is extra for the hydraulic supply circuit; a first suction inlet that communicates with one of the suction oil path and the strainer and a second suction inlet that communicates with the other of the suction oil path and the strainer, and a balanced vane pump.

A method and a Rotary Combustion Engine (RCE) suitable for deactivation of at least one rotor out of a plurality of rotors. The RCE includes at least a first shaft portion and a second shaft portion which are disposed in straight coextensive longitudinal axial alignment. Each shaft portion may support at least one rotor. The at least first shaft portion and second shaft portion are separated by a gap. A shaft coupling mechanism is operable to bridge the gap and couple the first shaft portion in engagement with the second shaft portion for rotation together. The shaft coupling mechanism is also operable to disengage the first shaft portion and the second shaft portion, and thereby deactivate the rotation of at least one rotor.

A coating device, e.g., for painting motor vehicle bodies, comprises a sprayer for applying a coating material by means of an application element and an internal color-changer valve assembly, said assembly having several color inlets for selecting coating materials of different colors. The internal color-changer valve assembly is integrated into the sprayer and is connected by its outlet to the application element, in order to feed the selected coating material to the application element. Further, an external color-changer valve assembly has several color inlets for selecting coating materials of different colors, said external color-changer assembly having a separate structure from the sprayer and being connected by its outlet to the application element, in order to feed the selected coating material to the application element. An operating method corresponds to the device.

A vane pump includes a first cam ring and a second cam ring, a first rotor positioned in the first cam ring and a second rotor positioned in the second cam ring, and a shaft. The first rotor is engaged with the shaft so that the first rotor rotates relative to the first cam ring about an axis extending through the shaft, and the second rotor selectively engages with the shaft so that the second rotor selectively rotates relative to the second cam ring about the axis. A piston positioned in the shaft translates within the shaft between a first position and a second position. When in the first position, the shaft engages with the second rotor so that the second rotor rotates relative to the second cam ring about the axis, and when in the second position, the shaft disengages with the second rotor so that the second rotor does not rotate relative to the second cam ring.
