  • Low deviation pressure relief valve for fuel pumps
    Patent number: 6840270
    Abstract: A low deviation pressure relief valve for a fuel pump consisting of a housing having an elongated bore having a continuous wall, an axis, shoulders arranged on the wall so as to extend toward the axis. A ball in the housing has a diameter at least less than the diameter of the bore and a ball retainer located in the bore upstream from the shoulders forms a ball seat by pre-coining process. The ball is smaller than the retainer seat in diameter to ensure an edge seal with the ball. A spring coaxial with the axis located down stream from the ball retainer and supported on the shoulders, and the ball is located between the spring and the ball seat wherein low flow restriction is created and reduced pressure variation is created as fluid flows past the ball and less buckling in the spring is created by guide ribs.
