Abstract: A valve seat (16?) for a fuel injector (10) includes a main body (27) having a proximal and a distal end with at least one orifice (24) extending through the main body. A seating surface (22) is provided on the main body to receive a closure member (20) of a fuel injector such that when the closure member engages the seating surface, the at least one orifice is closed. A guide surface (36) is provided on the main body to guide movement of the closure member. An annular wall (26) extends in a cantilever manner from the main body at the distal end thereof and defines an outer peripheral portion of the valve seat. The wall is constructed and arranged to deform during welding at the wall so as to isolate effects of the welding from the seating surface and the guide surface.

Abstract: A spring-actuator assembly (10) is provided for a fuel pressure regulator. The assembly includes a housing (30) and a washer spring (10) received in the housing. The washer spring has a body (12) with a top surface (13) and a bottom surface (15). The body includes an opening (14) there-through and a plurality of pleats (16, 16?) therein so that that first faces (20) of the top surface are disposed on a plane that is different from a plane of second faces (22) of the top surface. At least certain first faces define contact points (24). The assembly also includes an actuating member (26) disposed at least partially in the opening and engaging the contact points of the certain first faces such that a fluid flow passage (36) are defined between the washer spring and the actuating ball for dampening.

Abstract: A method of producing a laminated armature for a fuel injector provides providing a plurality of laminations (10) in plate-shaped strip stock material (12). Each lamination has a base (11) and a plurality of tabs (20, 22) extending from the base. The base and tabs are coplanar. The laminations are cut from the strip material, with the tabs having free ends (25). The tabs are bent so as to be generally transverse with respect to the base. The laminations are then stacked on top of each other and joined together. The free ends of the tabs are cut to define a generally planar impact surface.

Abstract: A mounting arrangement with a fuel rail having a plurality of fuel injector cups, a plurality of fuel injectors, and a clip. The fuel injector cups include a cylindrical tube defining a longitudinal axis, a fuel rail mounting section disposed at a first end of the tube, and a lip at a second end of the tube. Each of the fuel injectors corresponding to one of the plurality of fuel injector cups. The fuel injectors have a housing with a retention groove. The clip engages both the lip of the fuel injector cup and the retention groove in the housing of the fuel injector to secure the fuel injector to the fuel injector cup and allow the fuel injector to reciprocate along the longitudinal axis.

Abstract: A clip to couple a crossover tube to a fuel rail includes an annular body that extends along a longitudinal axis between a first end and a second end of the clip, the first end capturing the crossover tube. The annular body includes a first arcuate portion coupled to a second arcuate portion and a tab. An arm extends from the other of the first and second arcuate portions, the arm having serrations extending generally towards the longitudinal axis. The annular body includes at least one catch surface located on at least the first and second arcuate portions. The catch surface is coupled to the at least one boss portion of the at least one fuel rail to couple the clip to the fuel rail. A method of coupling the clip to the crossover tube prior to the clip being secured to the fuel rail is also disclosed.

Abstract: An integrated fuel rail portion and mounting bracket assembly is provided. The assembly includes an elongated support portion and at least one mounting bracket integrally connected to the elongated support portion. A method of forming the assembly is also provided.
