Patent number: 9200546Abstract: A device for adjusting the rotational angular position of a cam shaft relative to a crankshaft of a combustion engine includes a supply branch for supplying pressure fluid to setting chambers to generate torque acting on a rotor; and a pressure storage device arranged in the supply branch and including a spring and a storage chamber which can be filled with the pressure fluid against a spring force of the spring, wherein the storage chamber begins to fill, against the spring force, at a start-of-filling pressure which is at most as large as a hot idling pressure which the pressure fluid exhibits when the combustion engine is idling in its hot operational state, and continues to be filled against the spring force if the hot idling pressure is exceeded.Type: GrantFiled: December 8, 2011Date of Patent: December 1, 2015Assignee: Schwabische Huttenwerke Automotive GmbHInventors: Uwe Meinig, Jürgen Bohner, Franz Maucher

Publication number: 20120060683Abstract: A vacuum pump for supplying a machine assembly with a negative pressure includes a housing and a housing cover surrounding a delivery chamber. The delivery chamber includes a low-pressure region having a working inlet connected to the assembly, and a high-pressure region having a working outlet. A delivery member moveable within the delivery chamber, which, when moved, suctions air into the delivery chamber through the working inlet and expel it at an increased pressure through the working outlet. An outlet valve is arranged at or downstream or the working outlet and at least makes it difficult for air to flow back into the delivery chamber. The delivery chamber is connected to the external environment of the vacuum pump via a ventilating connection in order to establish at least partial pressure equalization with the external environment when the delivery member is stopped and a negative pressure prevails in the delivery chamber.Type: ApplicationFiled: September 9, 2011Publication date: March 15, 2012Applicant: Schwabische Huttenwerke Automotive GmbHInventors: Sven Peters, Franz Maucher

Patent number: 5765521Abstract: A supply pump for lubricant or heat transfer liquid of a conventional design is driven by a drive unit independently of the consumer of the lubricant or of the heat transfer liquid. In the event of the failure of the drive unit a forced connection occurs between the pump and the rotating parts of the consumer in order to ensure its supply with the lubricant or the heat transfer liquid at least for a sufficient emergency period. By the independent drive of the supply pump the supply to the consumer can be controlled according to the consumption of lubricant or heat transfer liquid independently of its individual operating characteristic or operating state.Type: GrantFiled: October 15, 1996Date of Patent: June 16, 1998Assignee: Schwaebische Huettenwerke GmbHInventors: Gunther Stutzle, Bernd Schrelber, Wolfgang Bruttel, Franz Maucher, Kurt Hoffmann
