Patent number: 10047874Abstract: A magnetic valve includes a valve component and a valve body that engages around a region of the valve component in a hood-like manner and in a sealing manner in at least one sealing region. A flow chamber is formed between the valve body and an end face of the valve component. The valve component has an axially running through-channel with a constant cross-section which passes through the end face and which opens into the flow chamber so as to form an axial duct for a fluid. The valve body has a through-opening that is fluidically connected to the flow chamber and is configured to be closed by a closing element that is movably arranged on a valve body face that faces away from the flow chamber. The end face is configured as a type of lip seal ring.Type: GrantFiled: May 8, 2012Date of Patent: August 14, 2018Assignee: Robert Bosch GmbHInventors: Andreas Karl, Reinhard Fink, Dirk Foerch

Patent number: 9707940Abstract: A hydraulic device of a vehicle braking system includes a storage reservoir configured to store brake fluid. The hydraulic device further includes a pump with a suction side configured to set a brake fluid pressure in at least one associated wheel brake. The hydraulic device also includes a line connection interposed between the storage reservoir and the suction side of the pump. In addition, the hydraulic device includes a high-pressure switching valve arranged in the line connection. The high-pressure switching valve is configured to possess an opening pressure of less than 1 bar. Further, the hydraulic device includes at least one brake circuit, and the at least one brake circuit includes the pump, the line connection, and the high-pressure switching valve.Type: GrantFiled: October 27, 2015Date of Patent: July 18, 2017Assignee: Robert Bosch GmbHInventors: Dirk Foerch, Volker Edelmann, Julia Jeschke, Michael Dinerman
