Abstract:
A device for cooling brake fluid in a cylinder of a brake element, comprising first and second flow channels wherein first ends of said first flow channel and second flow channel are connected to the cylinder of the brake element, and second ends of said first flow channel and second flow channel are connected to a fluid pressure generating unit which generates fluid pressure in accordance with a depressed amount of a brake pedal and at least one of said first and second flow channels is at least provided with means for generating a difference between an amount of brake fluid supplied to and an amount discharged from said cylinder to apply and release said brakes respectively through said first and second flow channels, wherein an absolute value of a difference between an amount of said brake fluid supplied to and an amount discharged from said cylinder in said first flow channel is made equal to an absolute value of a difference between an amount of said brake fluid supplied to and an amount discharged from said cylinder in said second flow channel so as to circulate said brake fluid in said cylinder using both of said first and second flow channels, and a pressure adjusting unit including a pump which is remote from the brake cylinder and disposed in one of said first and second flow channels, said pump circulating said brake fluid through said first and second flow channels and the cylinder during a braking operation so as to prevent overheating of said brake fluid.
