Patent number: 10564652Abstract: A valve includes a body defining first and second connection points, a valve slider, a spring, and a choke. The valve slider delimits first and second apertures to enable conduction of pressurized fluid from the first connection point to the second connection point via the first aperture, and is configured to move in an adjustment direction to close the first aperture. The choke is configured to enable conduction of pressurized fluid from the first connection point to the second connection point via the second aperture and via the choke. A first control point is defined between the choke and the second aperture. A second pressure at the first control point and a force of the spring pushes the valve slider in the adjustment direction, and a first pressure at the first connection point pushes the valve slider against the adjustment direction.Type: GrantFiled: November 14, 2016Date of Patent: February 18, 2020Assignee: Robert Bosch GmbHInventors: Thomas Mueller, Konrad Schneider

Patent number: 9851015Abstract: A valve includes a housing, in which a first valve body is accommodated so that it is moveable in a direction of a longitudinal axis, a first valve seat configured to be closed by the first valve body and arranged on the housing, a first fluid flow path extending from a first connection via the first valve seat to a second connection, a second valve seat closeable by a moveable second valve body, the second valve body formed separately from the first valve body, a second fluid flow path extending from the first connection via a bypass duct in the first valve body, onwards via the second valve seat to the second connection, so that pressure at the first connection is limited upwardly by the first and the second valve body in that hydraulic fluid is led to the second connection via the first fluid flow path.Type: GrantFiled: September 29, 2015Date of Patent: December 26, 2017Assignee: Robert Bosch GmbHInventors: Ralf Neubauer, Liebhart Zaiser, Thomas Hirsch, Ludmilla Graf, Harald Hahn, Konrad Schneider, Dominik Wolf

Patent number: 9027598Abstract: A steplessly adjustable hydraulic insert valve has a housing defining a radial direction and an end side in an installation direction. An inflow connector on the end side is connectable to a pressure medium source. First and second working connectors and a return connector are arranged in the radial direction. The return connector is connectable to a pressure medium tank. The housing has an axial bore and an actuator guided movably therein. The actuator can be held in an axial center position by at least one spring and is adjustable steplessly axially out of the center position by controllable actuation. At least one of the working connectors is fluidically connectable to the return connector by axial adjustment of the actuator. The actuator has a radial widened portion with first and second control edges for steplessly opening and/or closing first and second radial openings, respectively, of the return connector.Type: GrantFiled: November 18, 2013Date of Patent: May 12, 2015Assignee: Robert Bosch GmbHInventors: Konrad Schneider, Liebhart Zaiser, Andre Selke

Patent number: 7036788Abstract: A proportionally adjustable pressure limiting valve wherein a valve cone may be actuated via an armature of a proportional solenoid. The valve cone is cardanically supported in the armature. Additional guidance of the valve cone is effected through the intermediary of a housing-side guide, wherein the play between valve cone and housing-side guide is designed to be less than the play between valve cone and armature.Type: GrantFiled: November 12, 2003Date of Patent: May 2, 2006Assignee: Bosch Rexroth AGInventors: Konrad Schneider, Thomas Muller

Patent number: 6843508Abstract: A hydraulic device having a nut part with a threaded hole which has an internal screw thread with a defined nominal diameter and with a defined, uniform pitch, and having a screw part which has an external screw thread with the same nominal diameter as the threaded hole and with a defined, uniform pitch, which is screwed into the threaded hole. (In hydraulic devices, screw parts, in particular nozzle bodies, are generally adhesively bonded in place, in order to prevent them from becoming detached. Adhesive bonding has certain drawbacks, since the screw threads have to be free of grease, and in the case of nozzles there is a risk of blockages, adhesive can enter the hydraulic circuit and also process reliability is not ensured during application.) There is provided a slight difference between the pitch of the internal screw thread of the nut part and the pitch of the external screw thread of the screw part.Type: GrantFiled: April 27, 2001Date of Patent: January 18, 2005Assignee: Bosch Rexroth AGInventors: Karl Cords, Frank Hofmann, Peter Lauer, Götz-Dieter Machat, Karl Meyer, Konrad Schneider, Hans Wölfges

Patent number: 5526264Abstract: An anti-lock brake control system comprises at least two micro-computers and at least two input/output circuits which monitor one another as well as functions of other components of the anti-lock brake control system. If faulty voltages appear within the anti-lock brake control system or if false values in transmitted signals occur, the anti-lock brake control system will be dependably shut down. By integrating a plurality of monitoring functions in the input/output circuits as well as by building redundancies into the anti-lock brake control system, a high level of safety is achieved, in spite of the small number of necessary components and the small production cost associated therewith.Type: GrantFiled: July 6, 1992Date of Patent: June 11, 1996Assignees: Hella KG Hueck Co., Lucas Industries publ. ltd. & co.Inventors: Detlef Niggemann, Werner Wiegmann, Harald Bestmann, Gunther Heinz, Michael Keller, Detlef Staufenbiel, Konrad Schneider

Patent number: 5515278Abstract: A circuit has circuit amplifiers (T1, T2) and inductive loads (MV1, MV2) with the circuit amplifiers being controlled by control signals provided by a microcomputer (MC). The circuit accomplishes this control while monitoring a load circuit, comprised of the circuit amplifiers and the loads, and terminates control of the circuit amplifiers, without assistance of the controlling microcomputer, upon occurrence of incorrect voltages in the load circuit. Thus, the circuit of this invention allows particularly fast termination of control of the load circuit upon the appearances of critical voltages and also allows the monitoring of the load circuits by the microcomputer in a particularly uncomplicated manner.Type: GrantFiled: January 27, 1993Date of Patent: May 7, 1996Assignees: Hella KG Hueck & Co., Lucas Industries public limited companyInventors: Detlef Niggemann, Werner Wiegmann, Gunther Heinz, Konrad Schneider
