  • Patent number: 11846259
    Abstract: Provided is a pressure regulator and a fuel pump module having the same, which may be easily assembled by including fewer components, the pressure regulator including: a first housing including a guide part positioned therein and guiding movement of a valve, and an outlet part communicating with an inner space thereof and discharging a fluid; a second housing coupled to the first housing, having a valve accommodating space, including a valve seating part, and including an inlet part introducing a fluid; a valve positioned in the valve accommodating space, and moved to thus open and close a fluid flow; and an elastic member interposed between the valve and the first housing to bring the valve into close contact with the valve seating part.
    Type: Grant

  • Patent number: 10857706
    Abstract: Provided are an assembly type terminal for a fuel pump capable of decreasing a process additionally required at the time of injection-molding a flange using a separation type terminal according to the related art and preventing a defect of a product that may occur at the time of injection-molding the flange, and a method of manufacturing a fuel pump flange using the same. The assembly type terminal for a fuel pump includes: a plurality of power supply terminals; a plurality of coupling bodies 100 and 200 coupling one or more power supply terminals to each other; and a coupling member 300 formed in the coupling bodies and coupling the plurality of coupling bodies 100 and 200 to each other, wherein the plurality of coupling bodies are spaced apart from each other and are coupled to each other by the coupling member.
