  • Patent number: 7143995
    Abstract: A motorized cam actuator for linear actuation of an apparatus. An actuating motor shaft is fitted with a bushing having first and second opposed flats and a threaded portion at an outer end thereof. With the motor mounted to a pedestal, the bushing is rotated on the shaft to a predetermined angular position such that assembly stack up is cancelled. The bushing is then fixed to the shaft by welding. A cam with a central opening is mounted onto the bushing, the opening having flats for mating with the flats on the bushing. The cam is mounted onto the bushing and is secured thereto by a nut. This arrangement eliminates any relative motion between the bushing and the motor shaft and prevents stress on the weld joint from reaching failure levels.

  • Patent number: 6655611
    Abstract: An electromagnetic fuel injector comprises a body having a fuel inlet and a fuel outlet and a base comprising a valve seat sealably connected to the body. A disk-shaped armature disposed at the fuel outlet for controlling the flow of fuel has an upper surface and a lower surface that comprises a sealing interface with the valve seat. A ring-shaped flexural element comprising a plurality of spaced flexural legs is in contact with the injector body and the upper surface of the armature and provides a spring bias between the body and armature upper surface. When the injector is closed, spring bias between the body and armature upper surface maintains the armature in a sealing position with the valve seat, and when the injector is open, increased spring bias between the body and armature upper surface impels the armature to return to a sealing position with the valve seat.

  • Patent number: 6454192
    Abstract: An injector coil body assembly with upper and lower coil bodies is held together with a spring type press fit instead of welding. The coil bodies are made with generally tubular connecting portions telescoped together around the magnetic coil. The downwardly open tubular lower portion of the upper body is longer and slightly smaller than the connecting upwardly open tubular upper portion of the lower body so that the lower portion of the upper body fits into the upper portion of the lower body. A longitudinal slot in the upper body lower portion allows the lower portion to spring in slightly upon insertion into the lower body upper portion so that the upper and lower bodies are retained in assembly by a spring biased press fit. The press fit holds the telescoped portions in close contact, providing an efficient path for carrying the magnetic flux of the coil.

  • Patent number: 6360440
    Abstract: A method for locating an injector ball valve guide in alignment with a valve seat mounted in a common recess of an injector valve body. The valve guide is a disk that has a central opening which guides a valve ball of an associated valve member. During assembly, the guide disk is aligned with the valve seat by a locating tool having an oversized ball on a load rod. The oversized ball is fitted closely within the central opening of the guide and is seated on the ball seat to align the seat and opening. The valve seat and guide disk are then locked in the recess by crimping edges of the recess against the valve seat. The locating tool is removed and assembly of the remaining injector components is completed. The method simplifies alignment of the seat and guide components. In a variation of the method, the guide is aligned with and fixed to the valve seat with the oversized ball in place to form an aligned subassembly for subsequent installation into a fuel injector.
