Patent number: 11104313Abstract: A piston pump is configured to convey pressure medium in a pressure medium circuit, in particular in a braking circuit of a motor vehicle braking system that may be electronically controlled to counteract slip. The pump piston delimits an operating chamber and is received in a displaceable manner in a pump cylinder and may be driven to produce a stroke movement that goes back and forth between two reversing positions. The operating chamber may be connected in a controllable manner to a pump inlet or outlet. A pressure medium connection is provided from the pump outlet to the operating chamber, said pressure medium connection is controllable in dependence upon a relative position of the pump piston with respect to the first reversing position. Pressure pulsations of the piston pump are prevented and the operating noise is reduced.Type: GrantFiled: December 6, 2018Date of Patent: August 31, 2021Assignee: Robert Bosch GmbHInventors: Jens Norberg, Andreas Lechler, Patrick Schellnegger

Publication number: 20210061245Abstract: A valve cartridge for a solenoid valve, includes a capsule, a magnet armature which is guided in a movable manner within the capsule, a valve insert, and a valve body which has a main valve seat. The magnet armature, which is moved by a generated magnetic force, acts within the valve insert on a closing device, which has a plunger and a sealing element. The sealing element, in the currentlessly open state, opens up the main valve seat and, in the electrically energized, closed state, projects sealingly into the main valve seat of the valve body. The plunger and the sealing element are formed as separate components, and the sealing element is guided axially and/or radially by a guide device, which includes multiple guide balls arranged between the sealing element and an inner wall of the valve insert.Type: ApplicationFiled: July 29, 2020Publication date: March 4, 2021Inventors: Jens Norberg, Andreas Lechler, Patrick Schellnegger

Patent number: 10508754Abstract: A valve device includes a valve body that forms a throttle cross section and a valve element that sets the throttle cross section depending on the pressure. To avoid pulsation-induced noises, the valve element is configured with a flow-deflecting member that causes action upon the valve element with a transverse force. The flow-deflecting member prevents noise-causing vibrations of the valve element and permits a lower throttling effect of the valve device, in particular when volumetric flows are increased. A damping device, in particular for damping pressure pulsations in a brake circuit of a slip-controllable vehicle brake system, includes the valve device.Type: GrantFiled: August 1, 2016Date of Patent: December 17, 2019Assignee: Robert Bosch GmbHInventors: Jens Norberg, Patrick Schellnegger, Andreas Lechler

Patent number: 10385833Abstract: A reciprocating pump, in particular a hydraulic pump of a slip-controlled vehicle braking system, includes a step piston, a differential pressure valve, and a pump outlet. The step piston includes a piston step that delimits a stepped space which is in communication with the pump outlet via the differential pressure valve. The piston step is configured such that the step space undergoes suction and displacement in a direction opposite to a displacement space, and in smaller quantities than suction and displacement in the displacement space, such that brake fluid volume flow in the pump outlet is evened out, and such that pressure pulsations are inhibited.Type: GrantFiled: September 9, 2015Date of Patent: August 20, 2019Assignee: Robert Bosch GmbHInventors: Jens Norberg, Patrick Schellnegger, Andreas Lechler, Oliver Gaertner

Patent number: 10227065Abstract: A damping device, for example for damping pressure pulses in a brake circuit of a slip-controllable hydraulic vehicle brake system, includes a damper chamber with a pressure medium volumetric capacity, which can be varied in a pressure-dependent manner, and a flow resistor connected downstream thereof. Disadvantageously, the pressure medium volumetric capacity of the damping device is not available for the brake pressure build-up when the brake pressure is generated by the driver, and the pedal travel on a brake master cylinder of a vehicle brake system is therefore lengthened. A mechanism limits the pressure medium volumetric capacity of the damping device in the case of a passive braking operation. In the case of partially active or fully active braking operations, in contrast, the mechanism has no effect and the full scope of the pressure medium volumetric capacity of the damping device is available for damping pressure pulses.Type: GrantFiled: March 23, 2015Date of Patent: March 12, 2019Assignee: Robert Bosch GmbHInventors: Jens Norberg, Patrick Schellnegger, Andreas Lechler

Patent number: 10214192Abstract: In one embodiment, a solenoid valve for a vehicle braking system includes a magnet assembly having a winding support, a coil winding, a housing, and a cover disc. The solenoid value further includes a valve cartridge having a capsule, a valve insert, a valve seat, and an armature. The valve insert can be connected to the capsule, the armature can be guided within the capsule in an axially movable manner and has a closing element. The closing element and the valve seat can form a valve that can control a fluid flow through the valve cartridge. The coil winding can be wound on the winding support to form an electrical coil, which can be controlled using control signals applied to electrical connectors. The electric coil generates a magnetic force that can move the armature against a force of a return spring.Type: GrantFiled: August 4, 2015Date of Patent: February 26, 2019Assignee: Robert Bosch GmbHInventors: Andreas Lechler, Jens Norberg, Martin Haas
