Abstract: An overmolded coil assembly is provided and includes a body having a generally hollow cylindrical shape and including a central aperture and an inner surface defining a recess. A spool is received in the recess of the body. The spool includes an annular barrel and has opposite first and second ends. The first end is adjacent the central aperture of the body. A coil of electrically conductive wire is disposed in and circumferentially surrounds the annular barrel of the spool. A washer having inner and outer surfaces is adjacent the second end of the spool. An overmold made of an electrically insulative material covers the spool, the coil, the washer, and the body to seal around the spool, the coil, the washer, and the body. A fuel pump including the overmolded coil assembly and a method of sealing a coil assembly are also provided.

Abstract: A fuel pump includes a pump housing with a pumping chamber an inlet valve bore. An inlet valve selectively provides and prevents fluid communication between an inlet of the fuel pump and the pumping chamber. The inlet valve includes an inner housing received within the inlet valve bore such that an outer periphery of the inner housing is sealed to an inner periphery of the inlet valve bore. An outer housing circumferentially surrounds the inner housing. An annular chamber is defined radially between the inner housing and the outer housing and axially between the outer housing and the pump housing. A sealing ring is located within the annular chamber such that the sealing ring is compressed axially against the pump housing and the outer housing.
