Patent number: 6709245Abstract: 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.Type: GrantFiled: November 22, 2002Date of Patent: March 23, 2004Assignee: GKN Sinter Metals GmbHInventor: Josef Bachmann

Patent number: 6695603Abstract: 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.Type: GrantFiled: September 4, 2002Date of Patent: February 24, 2004Assignee: GKN Sinter Metals GmbHInventors: Josef Bachmann, Eberhard Ernst
