摘要:
A high-pressure fuel reservoir is proposed in which the hydraulic connection between the connection fitting and the reservoir chamber is produced by a number of connecting bores. This reduces the stress peaks in the vicinity of the intersections of the connecting bore and reservoir chamber so that the compression capacity of the high-pressure fuel reservoir increases.

In a component, in particular a high-pressure part for a fuel injection system, having intersecting bores, at least one bore of the two intersecting bores is designed with a flat region, and the component has inherent compressive stresses in the area of the flat region of the bore. This yields an increase in strength of the component in the area of the intersection point of the two bores.
摘要:
A fuel injection system in which only one pump element at a time can aspirate fuel. As a result, it is attained that even in partial-load operation, all the pump elements are in operation, and as a consequence the smooth operation of the engine in partial-load operation is improved.

A high-pressure fuel accumulator for a common-rail fuel injection system of an internal combustion engine includes a tubular main body which is equipped with a plurality of connections. In order to provide a high-pressure fuel accumulator which may be used for a large number of similar engines, a continuous connecting strip or several connections, whose dimensions in the longitudinal direction of the tubular main body are greater than the space required for connections, are provided on the tubular main body.

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).

摘要:
In a fuel high pressure accumulator for fuel injection devices an intersecting region between a storage chamber and a connection opening of a connection pipe, as well as a region of an outer wall which is opposite to the connecting region are designed to improve pressure strength.

The invention relates to a high-pressure fuel reservoir for a common rail fuel injection system of an internal combustion engine, with a tubular base body which has a blind bore extending in the longitudinal direction and a number of connections. In order to improve the high-pressure-tightness and the service life of the high-pressure fuel reservoir, a stopper is disposed in the closed end of the blind bore.
摘要:
A screwed connection has at least one first component (1) which is provided with an internal screw thread (2) and which is screwed together with a second component (3) which is provided with a matching external screw thread (4). The screwed connection is used to transmit a tightening power (F). Thread sealants (6) are introduced between the external and the internal screw thread, thereby sealing the screwed connection.
