Publication number: 20050116068Abstract: In an injection nozzle (1) with fuel filter for reciprocating-piston internal-combustion engines, with a filter body (8) in the pressure line (13) of a nozzle holder (2) comprising holding body (3) and nozzle body (4), there are formed filter surfaces or filter slots by boreholes in the filter body (8) and filter elements disposed movably therein. The filter elements are loose balls (19), which form filter slots together with the walls of the boreholes (18), and thus can pulsate because of the flow and dynamically reduce the size of residues.Type: ApplicationFiled: February 1, 2003Publication date: June 2, 2005Inventors: Gunter Kampichler, Herbert Geier

Publication number: 20040200302Abstract: A device for compensating for the tooth backlash between two toothed gears in engagement with one another, with a toothed disk, which is connected in parallel with one of the toothed gears and provided with the same gear pitch, and which is held such that it can be hydraulically adjusted relative thereto until it bears against the non-force-transmitting tooth flanks of the mating toothed gear. In order to achieve a design that is as simple as possible and requires little mounting space, there must be provided at least one hydraulic adjusting element, which exerts an adjusting force in circumferential direction on the toothed gear and which is equipped with a steel piston held adjustably in a housing and urged by a spring as well as by pressurized fluid supplied via a check valve.Type: ApplicationFiled: April 28, 2004Publication date: October 14, 2004Inventors: Gunter Kampichler, Ernst Gschweitl

Patent number: 6612278Abstract: A pivoting or rotating mounted rocker arm, for a valve train in an internal combustion engine, fitted with a mechanical valve play adjuster element, for the independent setting/adjustment of a first pre-set valve play between rocker arm and valve stem end. The valve play adjuster element comprises a hollow cylinder mounted in the rocker arm in a rotating manner, with planar surfaces (slide patches) formed around the hollow cylinder circumference and a turning spring which turns the slide patches in a predetermined direction. The independent rotation of the slide patches is prevented by contact of the relevant rear surface edge of the planar surface on the valve stem end, so long as a second given valve play is not reached.Type: GrantFiled: October 7, 2002Date of Patent: September 2, 2003Assignee: Motorenfabrik Hatz GmbH & Co.Inventor: Gunter Kampichler

Patent number: 6116522Abstract: A fuel injection device for diesel engines, with a nozzle holder (1), the pressure channel (2) of which is connected with the fuel injection pump on the one side, with the nozzle on the other side, comprises a nozzle body (3) which is connected with the nozzle holder (1) by means of a nozzle adjusting nut (10). For sealing purposes, there is an intermediate disk (13) between nozzle holder (1) and nozzle body (3). To seal the high-pressure connection in the region of the pressure channels (2, 4), there is a deformable metal sealing body which rests on a sealing surface and is held in a conical seat (19) in the region of the opening of the pressure channel (2) of the nozzle holder (1).Type: GrantFiled: October 16, 1998Date of Patent: September 12, 2000Assignee: Motorenfabrik Hatz GmbH & Co.

Patent number: 5957673Abstract: An injection pump for a diesel engine has a pump cylinder with a pump piston slideably mounted therein. The piston has a broadened foot portion. A cam is mounted on the camshaft and a rocker arm is mounted on a pivoting axis and has a camshaft end and a pump-side end. Means are provided for holding the camshaft end of the rocker arm in substantial contact with the cam. The pump-side end of the rocker arm has contact means for contacting the piston and moving the piston in the cylinder as the rocker arm is pivoted. The contact means includes means for loosely coupling the pump-side end of the rocker arm to the foot portion of the piston.Type: GrantFiled: August 25, 1995Date of Patent: September 28, 1999Assignee: Motorenfabrik Hatz GmbH & Co. KG.Inventors: Gunter Kampichler, Herbert Geier

Patent number: 5655503Abstract: The invention concerns an internal-combustion engine with fuel injection, in particular a single-cylinder diesel engine, in which the fuel-injection pump (3) is connected to the fuel pressure line (23) by a constant-pressure valve assembly comprising a feed valve (28) and a pressure-relief valve (29) mounted with its direction of flow opposite to the feed direction. Both valves (28, 29) are fitted next to each other and off the cylinder axis in a separate valve housing located directly on top of the pump cylinder (5).Type: GrantFiled: May 7, 1996Date of Patent: August 12, 1997Assignee: Motorenfabrik Hatz GmbH & Co., KG.Inventors: Gunter Kampichler, Herbert Geier

Patent number: 5522304Abstract: A driver, used as a link between a piston of an injection pump and a drive element which rests freely against the end of the piston nearest the driver and moves with the piston, is attached to the drive element in such a way that, in order to establish the link between the piston and the drive element, the driver can be rotated over the widened face of a baseplate located at the end of the piston until it reaches a final position in which it is secured by the fact that it grips the piston.Type: GrantFiled: November 14, 1994Date of Patent: June 4, 1996Assignee: Motorenfabrik Hatz GmbH & Co. KGInventors: Gunter Kampichler, Herbert Geier

Patent number: 4611566Abstract: In a fuel injection pump for internal combustion engines, a leakage connection is provided for varying the fuel supply quantity and the supply onset in accordance with rpm. The leakage connection, in a pump piston executing the stroke movement, is effective only at the beginning of the supply stroke of the pump piston and becomes gradually less effective in stages in the middle rpm range. The leakage connection has an outer groove in the pump piston, a blind bore discharging in the piston end face, and at least one throttle bore connecting the blind bore with the bore bottom of the outer groove. The outer groove extends over only a portion of the circumference of the pump piston and parallel to the piston end face at a very small distance therefrom.Type: GrantFiled: December 18, 1984Date of Patent: September 16, 1986Assignee: Robert Bosch GmbHInventors: Gunter Kampichler, Karl Rapp

Patent number: 4510796Abstract: A method in which a plug-in pump, controlled by oblique edges, is inserted with the aid of an adjusting device into a pump fitting of an internal combustion engine and which without subsequent correction of the supply quantity guarantees an identical supply quantity for all the plug-in pumps of one engine. With a supply quantity adjusting member held firmly in a test position, the plug-in pump is inserted into the test pedestal and rotated until such time as the supply quantity corresponds to the set-point supply quantity, this rotational position marked by a slash mark on the flange of the plug-in pump. With a governor rod, which is part of the engine, locked in the basic test position, a second slash mark is subsequently made on the pump fitting by means of a dummy pump. Once the dummy pump has been removed, the plug-in pump is secured in the pump fitting of the engine with the slash marks in alignment.Type: GrantFiled: February 23, 1984Date of Patent: April 16, 1985Assignee: Robert Bosch GmbHInventor: Gunter Kampichler

Patent number: 4467767Abstract: A fuel injection pump for internal combustion engines having an equal-pressure relief valve, which has a structure requiring little space when installed and is provided with a fastener element. The equal-pressure relief valve comprises a pressure valve body, onto which a beaker-shaped filler piece protruding into the interior of the pressure valve spring is placed. The structural unit comprising the pressure valve body and the filler piece containing the relief valve is held together, even when the pipe connector fitting or the pressure valve spring is removed, by means of the transit fastener element provided with a fastener ring. The invention is applicable both to single and series fuel injection pumps as well as to distributor injection pumps, particularly when space for installation is restricted.Type: GrantFiled: March 18, 1982Date of Patent: August 28, 1984Assignee: Robert Bosch GmbHInventors: Gunter Kampichler, Heinz Kuschmierz, Bernhard Schenk
