Disclosed is a pump for generating at least two volume flows having a different pressure. Said pump comprises a pump cover, a pump housing, and a wheel set that is eccentrically mounted therein. The pump housing is provided with a suction slot and a pressure slot which are separated from each other by means of a first sealing web and a second sealing sew that is located opposite therefrom. The pressure slot is subdivided into a high pressure chamber and a low pressure chamber with the air of at least one additional sealing web, each pressure chamber being provided with a delivery port.

Pump with multiple volume streams

A motor vehicle hydraulic pump () is provided comprising a gerotor rotor set or planetary rotor set and at least two output stages. A first output stage () of the hydraulic plump () is connected to a lubricant, in particular, a clutch lubricant. A second output stage () of the hydraulic pump () is connected to at least one clutch () of the actuation thereof. The invention also provides a method for actuating at least one clutch which is arranged in the motor vehicle by means of a motor vehicle hydraulic pump, whereby an inter-connection of a volume flow outlet of the first step () and the second step () of the hydraulic pump () takes place according to requirements for actuating the clutch.

Motor vehicle hydraulic pump

The invention relates to a pump, in particular an oil pump, for internal combustion engines, comprising a pump case, with the pump case comprising a pump lid and a pump flange, with at least one toothed wheelset being arranged between the pump lid and the pump flange and the pump lid and the pump flange being connected via at least one distance element.

Gear pump having optimal axial play

A camshaft adjuster for an internal combustion engine comprises a stator having inwardly projecting stator vanes, which are distributed over the periphery of the stator and which have at least one stator vane accommodating pocket located in the stator. This stator vane accommodating pocket is open toward the interior and a stator vane planet gear is mounted inside the stator vane accommodating pocket. A rotor is mounted inside the stator and comprises rotor vanes having at least one rotor vane accommodating pocket open toward the exterior, inside of which a rotor vane planet gear is mounted. The stator vane planet gears mesh with a denticulated segment located on the outer periphery of the rotor between each of the rotor vanes, and the rotor vane planet gears mesh with a denticulated segment located on the inner periphery of the stator between each of the stator vanes.

Camshaft adjuster for an internal combustion engine

The invention relates to a pump, in particular to oil pumps for internal combustion engines comprising a gear assembly or rotor assembly with one each of a pressure and suction region arranged in a pump housing, which may be sealed from each other by means of an axially displaceable piston valve which defines a supply chamber and a housing cover, closing the pump housing. The pressure region comprises a pressure channel connected to the waist of the control piston, whereby the control piston cooperates with a plunger on the end thereof facing the supply chamber, which is arranged at right angles to the control piston. The plunger is pre-tensioned against the control piston by means of a pressure spring, and the plunger and control piston are connected by means of a sliding surface, arranged at an angle to the control piston axis.

Regulated pump

The invention is related to a toothed rotor set for a pump or engine consisting of a rotating outer rotor, which has an approximately star-shaped bore. The bore has a fine inner tooth system and an inner rotor aligned eccentrically inside it. The inner rotor has oil pockets for planetary gears. The planetary gears also have a fine tooth system with the help of which they roll on the fine teeth of the outer rotor. The planetary gears thus build a tooth system that translates into an outer tooth system. The outer tooth system has one tooth less than the inner tooth system of the outer rotor.

Eccentric toothed rotor set having planetary gears on the inner rotor

The invention relates to a toothed rotor set for a pump, especially for a lubricating oil pump for internal combustion engines, wherein the toothed rotor set has a toothed configuration similar to a toothed ring pump and functioning and operation of said toothed rotor set corresponds to that of a toothed ring pump.
