Patent ID: 7798577

Claim:
An apparatus for pressurizing a brake fluid comprising a brake control assembly including a brake fluid accumulator assembly comprising: a housing defining a first brake-fluid-accumulating piston bore and a second brake-fluid-accumulating piston bore and defining a brake fluid orifice in fluid communication with each of said first and second brake-fluid accumulating piston bores; a first piston slidably disposed in said first brake-fluid-accumulating piston bore and a second piston slidably disposed in said second brake-fluid-accumulating piston bore; a controllable bi-directional motor for moving said first and second pistons in a first direction to pressurize the brake fluid toward said orifice; and wherein said first piston is floatably disposed in said first brake-fluid-accumulating piston bore and capable of being pushed by said motor in said first direction and for moving in a second direction opposite of said first direction only in response to pressure from the brake fluid from said orifice and independently of said motor.
