  • Patent number: 10486657
    Abstract: Disclosed herein is a pump of an integrated brake system. The pump includes a motor, a gear unit which converts a rotating force of the motor into linear reciprocating movement, a piston assembly which is connected to the gear unit and reciprocates based on power conversion of the gear unit, a piston housing which accommodates the piston assembly, and a fixed rod fixedly disposed in the piston housing in a longitudinal direction. Here, the piston assembly includes a coupling groove formed therein, into which the fixed rod is inserted.
