A method of making a fluid injector for a gas turbine engine includes depositing material onto a piece of tube stock. The method includes machining the deposited material into a fluid injector component. Depositing can include laser cladding the material onto the piece of tube stock. The method can include placing or flowing braze into a braze joint location between the deposited material and another fluid injector component and forming the braze into a braze joint in the braze joint location.

A fuel pump for a direct injection system and having: a main body; a pumping chamber; a piston, which is mounted in a sliding manner on the inside of the pumping chamber; an intake duct, which ends in the pumping chamber; an intake valve, which is arranged along the intake duct; and a flow rate adjustment device provided with a control rod which is coupled to the intake valve and with an electromagnetic actuator which is configured to axially move the control rod. The flow rate adjustment device has a containing element, which houses the electromagnetic actuator, has an open end facing the intake valve, and ends with a “U”-shaped rim which has an outer ring which is arranged around the containing element at a given distance from a cylindrical wall of the containing element. An annular weld (22) is obtained between the main body and the outer ring of the “U”-shaped rim.

A fuel injector for an internal combustion engine includes: an electromagnetic actuating element having a solenoid coil, a core and a valve casing as the outer solenoid circuit component, and a movable valve-closure body, which cooperates with a valve-seat surface assigned to a valve-seat body. The core and a connection pipe are fixedly connected in an inner opening of a thin-walled valve sleeve and the valve casing at the outer circumference of the valve sleeve is fixedly connected to the valve sleeve by being pressed in/on.

A fuel rail assembly for an internal combustion engine is disclosed. It includes a main gallery and a plurality of fuel delivery outlets. Each fuel delivery outlet has an injector cup and an injector cup mounting connection arranged between the main gallery and the injector cup. A fixing bracket is adapted to fasten the main gallery to the engine. The fixing bracket is spaced apart from the injector cup and secured to the main gallery. A fastening element is provided to secure the fixing bracket to the engine. A rigid connection member is coupled to the fixing bracket extends between the fixing bracket and one of the injector cup and the injector cup mounting connection.

To improve the ability to layout delivery pipes by maintaining flexibility in a mounting position of an inlet pipe to a delivery pipe main body. 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 fuel rail assembly is disclosed. The fuel rail assembly includes an elongated tubular fuel rail and a plurality of fuel delivery lines for hydraulically coupling the fuel rail to fuel injectors. Each fuel delivery line has an injector cup, a pipe being arranged between the fuel rail and the injector cup, and a fixation bracket. A rigid connection is established between the fixation bracket and a portion of the pipe, the portion being spaced apart from each of the fuel rail and from the injector cup.

The injector cup, the pipe, and the fixation bracket are individual parts. The fixation bracket is spaced apart from the injector cup and from the fuel rail.

The present disclosure relates to fuel delivery systems for a motor vehicle. Some embodiments include a housing with a wall and a connector opening, a high-pressure connector including a wall circumferentially bordering a recess extending along a longitudinal central axis of the high-pressure connector, a radial indentation formed at the inner side in the wall in the housing connector region adjacent to the transition region, and an axial indentation formed at the outer side in the wall in the transition region adjacent to the intermediate region. The high-pressure connector may have a housing connector region, an intermediate region, and a transition region. An outer diameter of the high-pressure connector is larger in the housing connector region than in the intermediate region and the inner diameter is larger in the housing connector region than in the intermediate region. The wall of the housing delimits a recess around the connector opening. The housing connector region includes a protruding region suitable for making contact with the housing when said protruding region partially or fully enters the recess.

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.
