Abstract: 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.

Abstract: This invention concerns a fuel injection system for an internal combustion engine in which a cut-off is provided to interrupt the fuel supply. The fuel injection system has a pump element with a suction bore (3) wherein the suction bore (3) of the pump element can be closed by means of a valve body (70 arranged on a flexible tappet to interrupt the fuel supply.

Abstract: A venting device, with a vent valve (2), for the crankcase (1) of an internal combustion engine, especially for a one-cylinder diesel engine, is provided with a duct (9) for the gas-oil mixture downstream from the vent valve (2) in flow direction, said duct ending in an oil trap (3), a connection (4) via which the gas can reach the atmosphere being provided downstream from the oil trap (3).

Abstract: 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.

Abstract: 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).

Abstract: 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.
