Patent number: 11103815Abstract: An apparatus for filtering a liquid includes a filter housing, at least one filter element arranged in the filter housing, and at least one sensor unit. The at least one sensor unit includes at least one sensor and a radio module. The at least one sensor is configured to detect an operating parameter representative of a state of at least the at least one filter element or the apparatus.Type: GrantFiled: June 6, 2019Date of Patent: August 31, 2021Assignee: Robert Bosch GmbHInventors: Patric Brand, Adrien Mouaffo Tiadjio, Jochen Mueller, Peter Rehbein, Peter Stachnik, Sebastian Vornwald, Thomas Inderwies

Publication number: 20190107210Abstract: The invention relates to a spool valve (1), having a valve housing (4) and a substantially axially symmetric closing body (3) arranged for longitudinal movement in the valve housing (4). An inlet channel (5), a first outlet channel (6a), and a second outlet channel (6b) are formed in the valve housing (4). The closing body (3) interacts with a first valve seat (8a) formed in the valve housing (4) by means of the longitudinal movement of the closing body and thereby opens and closes a first hydraulic connection between the inlet channel (5) and the first outlet channel (6a). Furthermore, the closing body (3) interacts with a second valve seat (8b) formed in the valve housing (4) by means of the longitudinal movement of the closing body and thereby opens and closes a second hydraulic connection between the inlet channel (5) and the second outlet channel (6b). The resulting hydraulic force on the closing body (3) in the axial direction is nearly zero.Type: ApplicationFiled: March 8, 2017Publication date: April 11, 2019Inventors: Bernd Berghaenel, Peter Stachnik, Sophie-Charlotte Deger-Panthene, Stephan Wehr

Patent number: 7997073Abstract: A hydraulic control system for controlling preferably at least two consumers, has a pump supplying the consumers with a pressure medium and having an adjustable pump capacity, an adjustable metering orifice assigned to each of the consumers, a power-beyond connection to which at least one power-beyond consumer is attachable, an inlet pressure scale connected downstream of the pump and provided in a pressure medium flow path between the pump and at least one of the two consumers, wherein the power-beyond connection branches off in the pressure medium flow path between the pump and the inlet pressure scale, a spring with a force acting upon the inlet pressure scale in a closing direction, an inlet having a pressure acting upon the inlet pressure scale in an opening direction, wherein the inlet pressure scale is configured so that it is actable upon in the closing direction selectively by either a highest load pressure or by a pressure that is greater than the highest load pressure.Type: GrantFiled: August 20, 2008Date of Patent: August 16, 2011Assignee: Robert Bosch GmbHInventors: Gerhard Keuper, Heinrich Loedige, Peter Stachnik, Milan Djurovic

Patent number: 7870728Abstract: The invention discloses a hydraulic control arrangement for controlling a number of consumers, particularly of a mobile working machine. In addition to the consumers of the control arrangement, an additional consumer should be able to be connected to a power beyond port. All consumers and power beyond consumers are supplied with hydraulic fluid by a pump. An input pressure scale is provided downstream of the pump, and the greater of the load pressures of the consumers or of the at least one power beyond consumer is applied to the control port of said input pressure scale.Type: GrantFiled: October 6, 2005Date of Patent: January 18, 2011Assignee: Bosch Rexroth, AGInventors: Gerhard Keuper, Peter Stachnik, Heinrich Loedige, Soenke Jessen
