Abstract: A high-pressure fuel accumulator for a common-rail fuel injection system of an internal combustion engine has a tubular main body (1) to which is welded at least one bushing (13) for connecting a high-pressure line (6). To improve the quality and safety of the high-pressure connections, a collar (14) is formed on the end of the bushing (13) facing the main body (1).

Abstract: A high-pressure fuel reservoir for a fuel injection system for internal combustion engines, which is supplied with high-pressure fuel by a high-pressure fuel pump and which has connections embodied as connection stubs, from each of the connection stubs one connecting bore discharges into the tubular body eccentrically to the axis of the tubular body. The tubular body is produced by forging, with three connecting stubs and fastening elements formed on by forging.

Abstract: A fuel injection system for internal combustion engines having a high-pressure fuel pump, which supplies fuel from a low pressure chamber via a supply line into at least one high-pressure accumulation chamber. The at least one high-pressure accumulation chamber communicates via high-pressure lines with injection valves, which protrude into the combustion chamber of the engine to be supplied and whose opening and closing movements are each controlled by an electrically triggered control valve disposed in the high-pressure line at the injection valve. In order to prevent an uncontrolled escape of fuel in the event of a breach of a high-pressure line, flow limiting valves are additionally provided in all high-pressure lines, which valves close these lines when an admissible throughput quantity is exceeded.

Abstract: The invention relates to a fuel injection pump for internal combustion engines, having a pump piston guided in a cylinder bore of a pump body, which pump piston defines a pump work chamber in the cylinder bore and which is axially driven by a cam drive counter to the force of a restoring spring. Each individual cylinder of the engine to be fed is assigned a fuel injection pump, which is inserted into a bore in the engine housing; at the same time, the engine housing serves as the pump housing. In order to limit frictional wear, which is caused by the back-and-forth motion of the roller tappet of the cam drive guided in the engine housing and to easily replace pump parts, a thin-walled slide bush is disposed between the roller tappet and the housing bore. The slide bush is fastened with radial play on the pump body and additionally prevents the roller tappet from slipping out and prevents the preassembled fuel injection pump from falling apart when it is not installed in the housing bore.
