The sliding lock latch also includes a locking tab on its outer surface to prevent retraction of the connector sleeve from the connector body.

Present application discloses fuel supply device which includes: fuel injection valves respectively arranged on center axes of cylinders, fuel injection valves being configured to inject fuel into the cylinders; fuel distribution portion configured to distribute fuel to fuel injection valves; and fuel supply tubes configured to form supply paths for fuel from fuel distribution portion to fuel injection valves. Fuel distribution portion includes connection portions arranged in arrangement direction so as to be connected to fuel supply tubes. Connection portions include pair of reference connection portions situated at positions distant from each other in arrangement direction by distance between respective bore center axes of cylinders. Fuel supply tubes include pair of fuel supply tubes respectively connected to pair of reference connection portions and two fuel injection valves on two cylinders arranged adjacently to each other. Pair of fuel supply tubes have a common shape.

A fuel injector, including a valve insert and a plug extrusion coating, is described, the valve insert including a valve sear and a valve housing. The valve housing has an alignment device, which is equipped to align the valve insert in an injection molding die, and the plastic extrusion coating has a second alignment device which is equipped to align the fuel injector during assembly in an internal combustion engine.

The invention relates to a method for producing an electromagnetic valve assembly (10), a planar metal sheet (12), which has through-slots (16) extending parallel to a longitudinal axis (14) of the sheet, and a disc (18), which has disc projections (22) that are complementary in shape to the through-slots (16), being provided, the disc projections (22) being engaged with the through-slots (16), and a coil housing (38) then being formed by the planar metal sheet (12) being shaped by non-overlapping roller-deforming along the longitudinal axis (14) of the sheet, around a circumference (20) of the disc (18). The invention further relates to an electromagnetic valve assembly (10) which has been produced in particular by means of such a method.

The present disclosure relates to a pulsation dampening structure for a vehicle. The pulsation dampening structure includes a fuel rail, a rail plug disposed at an end portion of the fuel rail, and a pulsation dampening part disposed on the rail plug to dampen pulsation generated when fuel enters. A turbulent flow is caused by reflecting fuel which was entered, and a vortex is generated in the fuel, thereby dampening pulsation.

A fuel injector (1) including a fuel injector housing (2), a valve seat (4) formed at one end of the fuel injector housing, and a valve body (10) disposed in the fuel injector housing and operable to open and close a spray hole (20) in the valve seat. The valve seat includes a base portion (16) and insert portion (26) having spray holes (8) that is secured to the base portion (16).

A high-pressure fuel pump for a fuel injection system of an internal combustion engine includes a pump housing and at least one fastening flange that is fixed to the pump housing by a welding. The welding has one weld region and at least one weld bead arranged laterally from the weld region. The weld bead is arranged in a receiving space formed between the pump housing and the fastening flange.
