Patent ID: 7367788

Claim:
A pump for an antilock-braking system, said pump comprising: a main body; a piston provided within a portion of said main body, wherein the piston is configured to reciprocate linearly; a piston spring provided within said main body, wherein the piston spring is configured to bias said piston toward an end of said main body; a plurality of intake check valves positioned radially within said main body and configured to move in a direction generally perpendicular to a linearly reciprocating direction of said piston such that brake fluid is introduced into said main body, the plurality of intake check valves comprising: a fluid intake passage provided in said main body and extending in a direction generally perpendicular to the linearly reciprocating direction of said piston, intake check balls positioned at opposing sides of said fluid intake passage with respect to a central axis of said piston, and an intake spring positioned between said opposing check balls, wherein the intake spring is configured to apply a resilient force to said opposing intake check balls; and an exhaust check valve configured to exhaust brake fluid from an inside of said main body to an exterior of said main body by moving an exhaust check ball in the linearly reciprocating direction of the piston.
