Patent number: 7992443Abstract: A sensor design, respectively a micromechanical sensor structure for capacitive relative-pressure measurement, that will allow very small pressure differentials to be reliably recorded at high absolute pressures even in harsh, particle-laden measuring environments. For that purpose, the micromechanical sensor element includes a deflectable diaphragm structure which is provided with at least one deflectable electrode, and a fixed support structure for at least one fixed counter-electrode which is located opposite the deflectable electrode. The diaphragm structure includes two mutually parallel configured diaphragms that are joined rigidly to one another via at least one connecting crosspiece, so that each application of force to one of the two diaphragms is directly transmitted to the respective other diaphragm.Type: GrantFiled: December 22, 2009Date of Patent: August 9, 2011Assignee: Robert Bosch GmbHInventors: Bernhard Opitz, Christian Doering, Hans Artmann, Janpeter Wolff, Remigius Niekrawietz

Publication number: 20110185887Abstract: A brake booster includes a housing configured for mounting to the master cylinder of a braking system. The housing defines a bore for receiving a power piston and an end cap, with a return spring disposed between the head of the piston and end cap. The housing and end cap define a recess and a rib sized to be received within the rib but configured for an interference fit between the end cap and housing outside the recess. The interference fit is calibrated to require a force to push the end cap into the bore that exceeds the force generated by the return spring when it is compressed between the end cap and the piston head. The recess and rib at least temporarily retains the spring within the bore until the brake booster is mounted to the master cylinder.Type: ApplicationFiled: February 3, 2010Publication date: August 4, 2011Applicants: ROBERT BOSCH LLC, ROBERT BOSCH GMBHInventor: Larry E.

Publication number: 20110186158Abstract: Delivery units are already known which have a drive rotor and an output rotor driven by the drive rotor, which are supported in a housing, interact in a meshing manner through a spur toothing in each case and draw fluid through at least one inlet and push said fluid out through an outlet, wherein the inlet and the outlet are separated from each other by two separating webs. In order to control the flow rate through the delivery unit, a rotational speed control, a bypass control, or, for gases, a suction throttling, for example, can be carried out. A rotational speed control is energy efficient, but very expensive, because an electric motor must be used, the rotational speed of which can be controlled. In the bypass control, the fluid is delivered from the outlet through a bypass back to the inlet, which however is energetically unfavorable and connected to hydraulic losses.Type: ApplicationFiled: September 10, 2009Publication date: August 4, 2011Applicant: ROBERT BOSCH GMBHInventors: Thomas Steidten, Ingo Samerski, Ingo Nowitzky, Niccolo Haegele, Jens Schrader, Guido Daimer
