A holding device is used for fastening a fuel distributor to an internal combustion engine. A plurality of holding elements is provided, which are able to be fixed in place on the internal combustion engine via a fastener. A cable guide is provided in addition. The holding elements are connected to the cable guide. In addition, a system having such a holding device and a fuel distributor for conveying fuel are provided.

A system, which is used in particular as a fuel injection system for the high-pressure injection in internal combustion engines, includes a fuel distributor and a plurality of fuel injectors. Each fuel injector is situated on a cup of the fuel distributor. At least one of the fuel injectors is fastened to the associated cup by a holding element, which has a supporting surface. The cup has a contact surface on an underside, by way of which the cup is supported at the supporting surface of the holding element by a damping layer. The holding element is attached to the cup. In addition, the fuel injector has a collar, which is braced on the holding element. Because of the damping layer, vibrations are able to be dampened, and the noise transmissions is able to be reduced.

A pipe connection arrangement for a fluid management system includes a pipe nut for releasably connecting an end portion of a pipe to a fluid port of the fluid management system. The pipe nut has a first portion having a toothed outer profile and a second portion configured to engage with a connection point portion of said fluid management system. An elongated drive member having a first end portion with a toothed outer profile is configured to cooperate with the toothed outer profile of the pipe nut, the first end portion further being configured to concentrically engage with a supplementary guide member adapted to be fixedly arranged adjacent the connection point portion of said fluid management system. When the elongated drive member is in engagement with the supplementary guide member, and the second portion of the pipe nut is in engagement with the connection point portion, the toothed outer profile and the toothed outer profile of the pipe nut are permitted to mesh together such that a rotation of said elongated drive member causes a corresponding rotation of the pipe nut for clamping the end portion to the fluid port or unclamping the end portion from the fluid port.

A pump actuator for use between a cam and a pump includes an outer body, an inner body, an axle and a bearing. The outer body has an outer body inner surface. The inner body is received by the outer body. The inner body has an inner body outer surface. The axle is supported by the inner body. The bearing is supported on the axle. The inner body includes at least one stamped feature protruding outwardly from the inner body outer surface. The at least one stamped feature is configured to form an interference fit with the outer body inner surface.
