Patent number: 11808355Abstract: A coolant regulator is provided including a housing having a coolant chamber and a rotary vane arranged therein, a drive shaft leading out of the coolant chamber that rotates the rotary vane, and a shaft seal which seals the coolant chamber from the surroundings. The shaft seal seals against a housing inner lateral surface of a housing recess and sealingly encloses the drive shaft. An end portion of the shaft seal facing the rotary vane is a circular ring that, under elastic deformation of the bead thereof, seals against the housing inner lateral surface on the outer circumference and encompasses a spreading ring on the inner circumference that limits an axial shift of the shaft seal toward the rotary vane to a dimension d<s. s is the axial distance between the bead center of the undisplaced shaft seal and the opening of the housing recess facing the rotary vane.Type: GrantFiled: September 3, 2020Date of Patent: November 7, 2023Assignee: Schaeffler Technologies AG & Co. KGInventors: Huilan Zhou, Thomas Traudt

Patent number: 8807096Abstract: A heat management module of a cooling system of an internal combustion engine which has a valve housing that includes at least one first feed connection for cooling water of a bypass circuit and at least one adjacent second feed connection for cooling water of a radiator circuit. The feed connections can be connected to a discharge connection depending on the position of a valve member accommodated in the valve housing. A driving element which actuates the valve member is provided on the valve housing. The driving element is a hydrostatic servo motor, which produces a rotating driving motion and which uses a feed pressure line that branches from the cooling system for pressurization.Type: GrantFiled: July 3, 2009Date of Patent: August 19, 2014Assignee: Schaeffler Technologies AG & Co.

Publication number: 20130152614Abstract: A thermal management module for the distribution as required of coolant flows in an electric vehicle, including a valve arrangement (4) having several valves (1, 2, 3). A first valve (1) for connecting a first cooling circuit (5) and a second valve (2) for connecting a second cooling circuit (6) as well as a third valve (3) for connecting a bypass circuit are provided, wherein the bypass circuit (7) allows bypassing a cooler (8) arranged in the first cooling circuit (5). The invention further relates to a cooling system for an electric vehicle having such a thermal management module.Type: ApplicationFiled: May 31, 2011Publication date: June 20, 2013Applicant: SCHAEFFLER TECHNOLOGIES AG & CO. KGInventors: Thomas Traudt, Michael Bogner

Publication number: 20120111291Abstract: A device (1) for regulating a coolant flow in a cooling system of an internal combustion engine (2) with a valve arrangement (3) that includes a rotary disk valve (4) for switching at least one cooling circuit (5, 6) and/or a bypass circuit (7), as well as a coolant pump (8) that is constructed as an impeller pump and is connected on the suction side to the valve arrangement (3). The coolant pump (8) has an axial adjustable guide plate (11) on an inside between two end stops (9, 10) for closing and releasing a pump outlet (12). The guide plate (11) for the axial adjustment is indirectly coupleable by a lead screw thread (13) to a drive shaft (14) of the rotary disk valve (4). A cooling system for an internal combustion engine (2) with such a device (1) is also provided.Type: ApplicationFiled: September 22, 2011Publication date: May 10, 2012Applicant: SCHAEFFLER TECHNOLOGIES GMBH & CO.

Publication number: 20080199319Abstract: The invention refers to an impeller, consisting of plastic, which Is intended for a coolant pump of an internal combustion engine. The impeller, which has a multipart construction, comprises a back wall, which is connected in one piece to guide vanes and also to a hub, and also a separate molded disk which on the end face partially covers the guide vanes in the installed state. The components, the back wall and the molded disk are positionally fixed by means of a materially bonding connection.Type: ApplicationFiled: June 17, 2006Publication date: August 21, 2008Applicant: SCHAEFFLER KGInventors: Elmar Mause, Patrick Jahnke, Thomas Traudt

Patent number: 7066471Abstract: A lip-type shaft seal is made of elastic material with a Shore A hardness of ?75, includes a radial sealing lip, which has a sealing edge to bear against a rotating component and terminates in a axial sealing lip, which has a sealing edge to rests in installed state against a contact surface. The axial sealing lip extends at an angle of ?35° in relation to a symmetry axis of the shaft seal, when the axial sealing lip has not been installed yet and is under no tension, and extends from the sealing edge of the radial sealing lip at a length of ?1.4 mm. When the shaft seal is installed, the axial sealing lip rests against the contact surface at an axial overlap of 0.05 to 0.55 mm.Type: GrantFiled: October 2, 2003Date of Patent: June 27, 2006Assignee: INA-Schaeffler KGInventors: Elmar Mause, Harald Peschke, Wolfram Kruhöffer, Thomas Traudt, Horst Krischer
