  • Patent number: 10738747
    Abstract: An injector for injecting fuel, which is introduced from a fuel rail, into an engine to supply the fuel thereto is provided. In particular, the injector includes a housing, an electromagnetic generation unit accommodated in the housing and formed to generate an electromagnetic field when electric power is applied thereto, a core inserted into a fuel-rail-side end of a bobbin to form a magnetic circuit using the generated electromagnetic field, a lead pipe inserted into an engine-side end of the bobbin to form the magnetic circuit by coupling with the core, a molding unit formed to enclose the electromagnetic generation unit and an outer peripheral surface of the core to block introduction of moisture, and a cover coupled to the outer peripheral surface of the core to constitute the magnetic circuit together with the core.

  • Publication number: 20200217287
    Abstract: The present disclosure relates to a ball and a valve seat for a fuel injector, in which an SiO-DLC functional layer having low friction properties is formed as an outermost layer in order to reduce a friction coefficient, a Mo-based material is applied to a bonding layer and a supporting layer for bonding the SiO-DLC functional layer to a base material and supporting the same to improve the heat resistance thereof, and only Mo particles of a pure ion state are deposited so as to form the bonding layer and the support layer, such that adhesive force and bonding force are increased to thus improve durability; and to a method for coating the same.
