Patent number: 7380528Abstract: In an hydraulic actuator, a movement of an actuating element of the actuator is effected in that a working chamber of the actuator, with the aid of a valve device, is able to be selectively connected to, and disconnected from, a fluid reservoir in which pressurized hydraulic fluid is stored. The lift of the actuating element of the actuator is a function of a fluid volume present in the working chamber. It is provided that, to ascertain an instantaneous operating performance of the actuator, the working chamber is briefly connected to the fluid reservoir, the corresponding pressure drop in the fluid reservoir is recorded, and the corresponding lift is determined from the pressure drop with the aid of known geometrical variables of the actuator.Type: GrantFiled: October 6, 2003Date of Patent: June 3, 2008Assignee: Robert Bosch GmbHInventors: Hermann Gaessler, Ulf Pischke, Hubert Schweiggart, Christian Grosse

Patent number: 7134408Abstract: A device for controlling gas-exchange valves of an internal combustion engine is provided, which device has hydraulic valve actuators each allocated to one gas-exchange valve. Each valve actuator has an actuating piston acting on the gas-exchange valve, and two hydraulic working chambers delimited by the actuating piston, of which the first working chamber acting upon the gas-exchange valve in the closing direction is constantly filled with fluid under pressure, and the second working chamber acting upon the gas-exchange valve in the opening direction is able to be alternately filled with fluid under pressure and relieved via two electric control valves. For the purpose of cost reduction, provided for each valve-actuator pair is a single first electric control valve that is acted upon with the fluid pressure on the intake side, and is connected on the outlet side to the second working chamber of one valve actuator.Type: GrantFiled: March 5, 2003Date of Patent: November 14, 2006Assignee: Robert Bosch GmbHInventors: Udo Diehl, Bernd Rosenau, Christian Grosse, Simon Kieser, Ralph Engelberg

Patent number: 6935286Abstract: The present invention relates to a connection between a shaft end of a gas exchange valve of an internal combustion engine and a sleeve-shaped actuating element of a valve actuator, which is guided in an axially movable manner within a pressure region, which is able to be pressurized with a pressure medium, of the valve actuator and at least partially surrounds the shaft end. The present invention provides for the connection to be situated outside of the pressure region and in the region of an opening, which is formed on the side of the valve actuator away from the combustion chamber, and is, for example, coaxial to the shaft end.Type: GrantFiled: July 20, 2001Date of Patent: August 30, 2005Assignee: Robert Bosch GmbHInventors: Georg Mallebrein, Hermann Gaessler, Udo Diehl, Karsten Mischker, Rainer Walter, Stefan Reimer, Simon Kieser, Andreas Baumann, Bernd Rosenau, Juergen Ulm, Sevan Tatiyosyan, Juergen Schiemann, Christian Grosse, Volker Beuche

Patent number: 6848400Abstract: A gas exchange valve device for an internal combustion engine is provided with a hydraulic apparatus which includes a fluid circuit and at least one pressure reservoir connected to the fluid circuit and containing piston prestressed by a device, and also includes a controllable actuating device. A gas exchange valve is also provided, whose valve element is acted on by the actuating device. In order to achieve a simpler design of the gas exchange valve device the pressure reservoir is disposed so that in an approximately unpressurized state of the pressure reservoir, its piston at least indirectly locks the valve element of the gas exchange valve in an essentially closed position.Type: GrantFiled: February 14, 2002Date of Patent: February 1, 2005Assignee: Robert Bosch GmbHInventors: Hermann Gaessler, Udo Diehl, Karsten Mischker, Rainer Walter, Juergen Schiemann, Christian Grosse, Volker Beuche, Stefan Reimer
