Publication number: 20070057471Abstract: A shaft seal has a support member and a sealing part having a sealing edge that seals a medium-containing space. The sealing part has at least one lubricating device on a side of the sealing part that is facing away from the medium-containing space. The at least one lubricating device is positioned in a receiving space and returns a medium, that has escaped from the medium-containing side into the receiving space by passing underneath the sealing edge when turning a shaft sealed by the shaft seal in a first direction, underneath the sealing edge from the receiving space into the medium-containing space when turning the shaft in a second direction opposite to the first direction.Type: ApplicationFiled: September 15, 2006Publication date: March 15, 2007Applicant: KACO GMBH + CO. KGInventor: Klaus Rentschler

Patent number: 6837261Abstract: A control valve assembly comprising at least two control valves which may be used, for example, to throttle the air intake of an internal combustion engine. The assembly is provided with a centrally arranged, force-transmitting shaft (32). The control valves are formed by blades (15) in frames (16) produced by an assembly injection molding process. The control valve blades (15) can be molded onto the force-transmitting shaft (32). The resulting assembly can be mounted or installed as a unit. Alternatively, instead of using a single continuous shaft, shaft projections can be injection molded on the valve blades, which terminate in lugs which engage in a rotationally secure manner in sockets in an adjacent valve assembly so that the two assemblies rotate together as a unit. The resulting control valve assembly is easy to install and advantageously takes up only a little space.Type: GrantFiled: June 26, 2003Date of Patent: January 4, 2005Assignee: Filterwerk Mann & Hummel GmbHInventors: Klaus Rentschler, Helmut Neuschwander

Patent number: 6732712Abstract: An intermediate flange system for an internal combustion engine with direct fuel injection. The intermediate flange system is mounted between the intake device and the cylinder head and includes two subunits (10, 11). The first subunit includes a basic body (12) and is responsible for conducting the fuel. The other subunit includes a basic body (13) and serves to conduct the intake air. Both basic bodies can be optimally designed as a function of demands to which they are subjected. Thus, basic body (13) is preferably made of synthetic resin material, and basic body (12) of aluminum. Consequently, the overall intermediate flange system is lighter than prior art systems, which heretofore have been made entirely of aluminum.Type: GrantFiled: June 25, 2002Date of Patent: May 11, 2004Assignee: Filterwerk Mann & Hummel GmbHInventors: Arthur Klotz, Klaus Rentschler, Joachim Schraudolf

Patent number: 6692675Abstract: A method for producing a control valve assembly using a mold comprising an upper mold half (20) and a lower mold half (21). A shaft (11) with premounted bearing blocks (13) or other functional components is placed in the mold, and the control valves subsequently are injection-molded on the shaft (11) in cavities (22) via feeders (23) to produce the control valve assembly. Afterward, the bearing blocks (13) can no longer be detached. Because they are produced separately, the bearing blocks can have a complex geometry. This allows a considerable degree of freedom in the geometric design of the control valve assembly while nevertheless ensuring cost-effective production.Type: GrantFiled: June 25, 2002Date of Patent: February 17, 2004Assignee: Filterwerk Mann & Hummel GmbHInventors: Joachim Schraudolf, Klaus Rentschler, Helmut Neuschwander

Publication number: 20030010321Abstract: An air intake device for an internal combustion engine with crankcase ventilation in which crankcase gases are conducted via a duct structure (25) into the interior (18) of the air intake device (10). The duct structure ensures a quasi cylinder-selective feed through a plurality of feed inlets (27) into individual intake channels (20a). The duct structure is formed by the wall of the intake manifold and is sealed by a cover, so that the intake manifold can be produced cost-effectively. This construction has the advantage of ensuring uniform distribution of the crankcase gases among the cylinders while simultaneously enabling economically efficient manufacture.Type: ApplicationFiled: June 26, 2002Publication date: January 16, 2003Applicant: Filterwerk Mann & Hummel GmbHInventors: Klaus Rentschler, Werner Wagner

Patent number: 6357751Abstract: A protective element for a sealing arrangement having at least one sealing ring has an annular bottom having an inner side and a radially outer side. A mantle portion is connected to the radially outer side. A cylindrical portion is connected to the radially inner side and has a central axis. The mantle portion and the cylindrical portion extend in opposite directions relative to the annular bottom. The cylindrical portion has a circumferential end face extending at least over a portion of the circumference at a slant relative to the central axis. Such a protective element prevents adhering of dust particles to the shaft and penetration of dust particles into the sealing arrangement.Type: GrantFiled: February 25, 1999Date of Patent: March 19, 2002Assignee: KACO GmbH & Co.Inventor: Klaus Rentschler
