A delivery pipe for gasoline comprising a flat shaped delivery pipe main body 1 provided with a pair of facing wide walls 2, 3 and a pair of facing narrow walls 4, 5 that are more narrow than the pair of wide walls 2, 3, wherein an inlet pipe 7 is disposed and connected to the narrow wall 4 of the delivery pipe main body 1, and a connecting portion 10 of the inlet pipe 7 and the narrow wall 4 is covered continuously by a reinforcing material 11 from the connecting portion 10 over the wide walls 2, 3, thereby reinforcing the connection portion 10.

A solenoid valve which regulates the pressure in a pressurized fuel injection system includes a body containing a needle that is pressed by an electromagnet including a coil and a magnetic core. The core has a cavity that is in fluid communication via an internal channel with a counterbore in the body into which the needle protrudes and into which fuel flows during use. The core also has a restriction which restricts the fluid communication and which attenuates pressure waves propagating in the fuel to prevent the waves from moving the core.

A structure for attaching a metal diaphragm damper, includes a housing, a housing cover that cooperates with the housing to define a space, and a pair of diaphragms each formed in a disk shape, the pair of diaphragms having weld portions on an outer periphery side thereof, the weld portions being welded to each other in an annular shape to form the metal diaphragm damper of which inside is filled with gas, the metal diaphragm damper being attached to the housing and the housing cover so as to be disposed in the space between the housing and the housing cover. The pair of diaphragms is provided with outer peripheral portions on the outer peripheral side of the welded portions, and the outer peripheral portions of the pair of diaphragms are held by the housing and the housing cover in a thickness direction of the pair of diaphragms.

The present disclosure relates to the field of motor vehicles. The teachings thereof may be embodied in a self-locking internal damper comprising: a damper body with a closed chamber; each of two ends of the closed chamber in the length direction including a straight plate section projecting therefrom, with a center line of the straight plate section passing through a center point of the closed chamber; two connecting portions located at ends of the two straight plate sections, respectively; and at least one of the two connecting portions including a bent structure formed by extending and bending one of the straight plate sections.

A damper cup houses a pulsation damper of a fuel pump such that the damper cup defines a fuel volume together with a fuel pump housing of the fuel pump. The damper cup includes a sidewall which is annular in shape and which extends along a damper cup axis from a sidewall first end to a sidewall second end. The damper cup also includes an end wall which closes the sidewall second end, wherein the sidewall includes a support shoulder which is transverse to the damper cup axis and which is a segment of an annulus extending uninterrupted about the damper cup axis from a shoulder first end to a shoulder second end such that the shoulder first end and the shoulder second end are separated from each other by a gap which is uninterrupted.

A fuel distributor, which is in particular used as a fuel distribution rail for mixture-compressing, spark-ignited internal combustion engines, including a base body, at which at least one high-pressure inlet and multiple high-pressure outlets are provided. An insert element is furthermore provided that is situated in an interior of the base body. In the interior, the insert element separates an inflow area, which extends from the high-pressure inlet to the high-pressure outlets, at least essentially from a damping area. The insert element is designed as a thin-walled insert element that forms a divider extending through the interior at least from the high-pressure inlet to the high-pressure outlets.

A fuel distributor, which is used, in particular, for fuel injection systems of mixture-compressing, internal combustion engines having externally supplied ignition, includes a distributor pipe, a first holder and at least one second holder. The distributor pipe has a longitudinal axis. In this connection, the first holder and the second holder are situated at the distributor pipe so as to be axially set apart from one another with respect to the longitudinal axis. The distributor pipe is designed to allow axial length compensation. It is also possible for at least one holder to be designed to allow axial length compensation.

A gas powered internal combustion engine in which the gas is provided from the gas phase of a pressurized liquid gas in an liquified petroleum gas container and in which the liquified petroleum gas container is rigidly mounted adjacent to the internal combustion engine at a preselected angle to be in conductive heat transfer relationship to the internal combustion engine and in vibration receiving relationship to the internal combustion engine whereby the liquified gas in the liquified petroleum gas container is heated and vibrated and the effective surface area thereof is thereby increased. A pressure regulator is provided for receiving the gas from the liquified petroleum gas bottle regulating the pressure of the gas transmitted to the internal combustion engine and at least one flexible hose is connected to the pressure regulator for transmitting the gas therethrough. A vibration and/or heat limiting member may be incorporated to reduce the frequence and amplitude of the vibration and limit the amount of heat transferred to the liquified petroleum gas.

A distributor apparatus of a common rail system for an internal combustion engine. The distributor apparatus is designed with at least one distributor device having a high-pressure line for fuel and a plurality of feed lines branching off from the high-pressure line within the distributor device. Each feed line leads to an individual accumulator and an injector. The feed line is associated with a restriction device and a discharge bore, which is designed to cooperate with a pressure-measuring device and which is arranged downstream of the restriction device, such that the restriction device is arranged in the feed line and the discharge bore, arranged in the distributor device, is connected to the feed line downstream of the restriction device.

To suppress the possibility that a body-side holding member comes into contact with a joint portion 92 of a damper mechanism 9. damper cover that is arranged on an upstream side of a pressurizing chamber and is attached to a body to form a damper chamber, a damper mechanism that is arranged in the damper chamber, and a body-side holding member that holds the damper mechanism from the body side are provided. The body-side holding member includes a bottom surface in contact with the body and a flexible portion formed along an urging direction by being urged downward from the damper cover toward the body.
