A compact injector armature valve assembly for a fuel injector allowing the O-ring to O-ring spacing to be reduced. The armature valve assembly is a cylindrical hollow magnetic piece, with a narrow necked down portion to act as the receiving end for a ball, which is directly attached to the necked down portion. The attachment of the necked down portion by means of crimping or chemical bonding above the mid-point of the ball allows the strengths of a pivot style guidance scheme to be used.

Fuel injector has combination valve-armature fabricated by laser welding relatively more magnetically permeable armature element to relatively less magnetically permeable valve element. Valve element contains sealing ring and landing ring, the latter being circumferentially discontinuous because of fuel passage holes through the valve element, the former being non-symmetrical so that magnetic opening force causes valve-armature to open by tilting about consistent circumferential location on valve element. Initial opening tilting motion is stopped by corrugated stop surface of annular stop member with final tilting motion occurring about the corrugated stop surface until the full perimeter of the valve element abuts the full perimeter of the corrugated stop surface. Actuator has bobbin-mounted coil inserted into frame and encapsulated by outer plastic body. Conical disk spring acting between fuel inlet tube and coil forces one end of the latter against valve body member while forming a barrier between fuel inlet tube and other end of coil so that plastic does not intrude into interior of mechanism during injection molding of outer plastic body.

A core assembly for an electromagnet includes a plurality of stacked laminations extending along a stacking axis. The laminations each having generally the same thickness in a direction along the stacking axis. A solid core member has opposing ends. The core member is disposed generally centrally with respect to the plurality of stacked laminations such that each end of the core member contacts a lamination of the plurality of laminations. The core member has a thickness in a direction along the stacking axis substantially greater than the thickness of a lamination. The core member also has an aperture therethrough disposed generally perpendicular to the stacking axis for receiving a shaft of an armature assembly.
