Title: BRAKE RESERVOIR WITH INTERNAL CONDUIT FOR INTEGRATED POWER BRAKE UNIT
Abstract:
An integrated power brake unit (20) includes an input rod (30) operable to receive a driver braking input force, a booster operable to boost the driver braking input force, a master cylinder, a pump operable to provide pressurized fluid for braking, in lieu of the master cylinder, in response to the driver braking input force, and a fluid reservoir (36) defining a main chamber. The fluid reservoir (36) has first and second outlet ports (P1, P2) in fluid communication to supply the master cylinder, and a third outlet port (P3) in fluid communication to supply the pump, each of the first, second, and third outlet ports (P1, P2, P3) being provided in a bottom wall (48) of the fluid reservoir (36). The fluid reservoir (36) includes a sub-chamber (42) within the main chamber, the sub-chamber (42) covering the third outlet port (P3), and defining an opening (56) to the main chamber at a forward-most end of the sub-chamber (42).
