  • Publication number: 20070193846
    Abstract: An axial setting device for actuating a multi-plate coupling (2) in the driveline of a motor vehicle, comprising a housing (3), a cylinder unit (15) and a hydraulic system. In the housing (3), two parts (4, 5) are supported so as to be coaxially rotatable relative to one another and can be coupled to one another by a set of coupling plates (10) which are axially arranged between a supporting disc (9) and a pressure disc (11). The cylinder unit (15) comprises a hydraulic chamber (22) and a piston (21) axially displaceably arranged therein for actuating the multi-plate coupling (10) via the pressure disc (11). The hydraulic system for actuating the piston (21) comprises a quantity of oil jointly contained in the housing (3) and in the hydraulic chamber (22), as well as a pump (18) which has a first connection (23) connected to the housing (3) and a second connection (24) connected to the hydraulic chamber (22).

  • Patent number: 6709245
    Abstract: 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.

  • Patent number: 6695603
    Abstract: 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.
