Patent number: 8590508Abstract: The invention relates to a method which uses an injection mold for the production of an intake system which is composed of plastic and is intended for internal combustion engines, and which has a plurality of parallel-running intake pipes and which has, arranged in the intake pipes, throttle flaps operated by way of a shared shaft bearing against bearings located in the walls of the intake pipe. A simplified production process is obtained if two mandrels (1, 2) of the injection mold, intended for formation of apertures for the bearings, are inserted respectively from one side of the injection mold in such a way that ends of the mandrels (1, 2) bear against one another in the injection mold, and if the method of production of apertures situated further outwards, with respectively greater diameter than the adjacent inwardly situated apertures is such that each mandrel (1, 2) is of staged shape, and the mandrels (1, 2) are drawn out during demolding at the two sides of the injection mold.Type: GrantFiled: September 10, 2007Date of Patent: November 26, 2013Assignee: Mahle International GmbHInventors: Werner Schnabel, Siegfried Deiss

Patent number: 5681988Abstract: An apparatus for indicating the extent to which an air filter in an internal combustion engine is fouled. For this purpose the apparatus includes a pressure sensor, a sensor to detect the rotational speed of the engine, and an additional sensor which determines the load state of the engine. The signals of the three sensors are combined and serve to produce an air filter dirtiness indicating signal.Type: GrantFiled: August 9, 1995Date of Patent: October 28, 1997Assignee: Filterwerk Mann & Hummel GmbHInventors: Volker Koch, Werner Schnabel

Patent number: 5335641Abstract: A pressure control valve for controlling the vacuum in a crankcase housing, which valve is disposed on an oil filler opening (33) and simultaneously acts as a cap for the oil filler opening. A tube 37 through which the crankcase gases are conveyed to the air intake of the internal combustion engine is provided in the oil filler opening. The pressure control valve serves to establish a certain vacuum in the crankcase, is of compact construction, and can be replaced or checked in a simple manner.Type: GrantFiled: April 13, 1993Date of Patent: August 9, 1994Assignee: Filterwerk Mann & Hummel GmbHInventor: Werner Schnabel

Patent number: 5080082Abstract: A pressure regulating valve for venting the crankcase of an internal combustion engine in which the pressure regulating valve is combined with a motor oil filler tube and with an oil dip stick. This combination is distinguished by the fact that it is especially compact, and centrally connects all of the components relating to oil supply and monitoring in an internal combustion engine. This combination is further characterized in that only one connecting opening is needed on the engine block for adding oil, for returning oil from the pressure regulating valve to the oil pan, and for accommodating the oil dip stick.Type: GrantFiled: May 10, 1991Date of Patent: January 14, 1992Assignee: Filterwerk Mann & Hummel GmbHInventors: Heinz Mueller, Werner Schnabel

Patent number: 4079503Abstract: A method of producing a solid electrolytic capacitor including the steps of producing a sintered anode on a capacitor body which anode has a dielectrically effective oxide coating, producing the capacitor cathode by immersing the capacitor in a bath containing a pyrolytically decomposable compound of the element needed for production of the cathode, and while still in the immersion bath, applying a given voltage to the capacitor body, then lowering the voltage to a further value, removing the capacitor body and producing the cathode by pyrolytic decomposition. A graphite layer is then applied in a known manner and an additional coating is produced by further immersing the capacitor body in another bath which contains a pyrolytically decomposable compound of the element needed for that additional coating. A voltage is also applied in the additional bath and after a lapse of time the capacitor is removed and finished in a known manner.Type: GrantFiled: June 28, 1976Date of Patent: March 21, 1978Assignee: Siemens AktiengesellschaftInventor: Werner Schnabel
