Patent number: 10670308Abstract: An adsorption refrigeration device includes a first chamber with an adsorber/desorber material and a second chamber with an evaporator/condenser device. The first and second chambers are in fluid connection via a pipeline. The fluid connection between the chambers is blocked in a first functional position and opened in a second functional position via a valve device that is arranged in the pipeline. The valve device has a valve element with a variable diameter. The valve element has two functional positions. In the first functional position, the valve element has a first diameter by which it fills an internal cross section of the pipeline with tight contact with an inner wall of the pipeline. In the second functional position, the valve element has a second diameter that is smaller than the first diameter such that a gap is opened between the inner wall of the pipeline and the valve element.Type: GrantFiled: November 5, 2014Date of Patent: June 2, 2020Assignee: Robert Bosch GmbHInventors: Andreas Eichendorf, Thomas Demmer, Ulrich Kappenstein, Ralf Diekmann

Publication number: 20060070665Abstract: The invention starts with a volume flow control valve (36, 38) with a flow restrictor (48, 54) that can be displaced axially in a housing (40, 44), via which the volume flow can be diverted. It is proposed that the flow restrictor (48, 54) have a diverting body (54) and the force generated by the diversion at the diverting body (54) be used to adjust the flow restrictor (48, 54).Type: ApplicationFiled: May 26, 2003Publication date: April 6, 2006Inventors: Manfred Schmitt, Karsten Mann, Ulrich Kappenstein

Patent number: 6332437Abstract: An adjusting unit for actuating a device for variable control of valves of an internal combustion engine for load control of the engine via the inlet stroke function of the valves. The adjusting unit includes a gear unit with a cylindrical worm, on whose circumferential surface a thread is embodied. A displacement element that meshes with the thread of the worm is guided displaceably on the worm, and the displacement element is in communication with an actuating element of the device. A drive unit sets the worm into a rotary motion about its longitudinal axis which drives the displacement element.Type: GrantFiled: March 27, 2000Date of Patent: December 25, 2001Assignee: Robert Bosch GmbHInventors: Udo Sieber, Ulrich Kappenstein

Patent number: 6298938Abstract: A locking device for use in motor-vehicle steering systems, the locking device having a blocking mechanism by which a pitman arm shaft can be locked, a steering wheel of the motor vehicle can be prevented from rotating and vehicle wheels of the motor vehicle can be prevented from being turned or steered. The blocking mechanism includes two end positions, one of which is unlocked and one of which is locked, and is electromechanically operable. An electromagnet causes concentric external gear teeth of the pitman arm shaft to mesh with internal gear teeth of an axially movable and radially non-rotatable locking ring so that the pitman arm shaft is not rotatable in the locked state.Type: GrantFiled: October 5, 2000Date of Patent: October 9, 2001Assignee: Robert Bosch GmbHInventors: Tobias Klaiber, Ulrich Kappenstein, Werner Schoenamsgruber

Patent number: 6279626Abstract: A closure for a tank, in particular a fuel tank for a motor vehicle or the like, that has a tank filling pipe which can be closed with a closure flap, is described. The closure flap has a locking device with which it can be locked and unlocked and is also connected by a hinge or the like, so that it can move into the interior of the tank filling pipe. The locking device is located completely beneath the closure flap so that the closure flap can be locked and unlocked. Thus the locking device is not accessible from the outside, so it cannot be damaged or operated by an unauthorized party. The tank filling pipe can also be sealed airtight by the closure flap or by a closure valve arranged in the tank filling pipe.Type: GrantFiled: September 18, 2000Date of Patent: August 28, 2001Assignee: Robert Bosch GmbHInventors: Manfred Schmitt, Ulrich Kappenstein

Patent number: 6178935Abstract: A valve control device for an internal combustion engine having a gas exchange valve for controlling an inlet and/or outlet cross section in the combustion chamber of the engine. The valve control device has an axially movable gas exchange valve member whose valve member shaft is coupled to a piston rod to a differential piston that can be hydraulically actuated. The differential piston is embodied as two piston parts, wherein the two piston parts are disposed in relation to one another in such a way that they are operatively connected to each other in the axial direction and can execute a radial relative movement in relation to each other.Type: GrantFiled: May 8, 2000Date of Patent: January 30, 2001Assignee: Robert Bosch GmbHInventors: Udo Diehl, Karsten Mischker, Rainer Walter, Stefan Franzl, Volker Beuche, Stefan Reimer, Ulrich Kappenstein
