Abstract:
A reservoir for a tandem-type hydraulic master cylinder of a vehicle comprising:a fluid injection port disposed on an upper portion at a front side of said reservoir; a bottom wall defining a first union hole and a second union hole respectively adapted to communicate with cylinder holes formed in said tandem-type hydraulic master cylinder; a level detector arrange in a fluid chamber inside said reservoir, said level detector having a lead switch and a float; and first and second partition walls respectively at least partially extending along a widthwise direction of said reservoir and extending from said bottom wall within said fluid chamber so as to divide said fluid chamber in a first fluid chamber, a second fluid chamber and a third fluid chamber in this order from the front side of said reservoir, wherein said fluid injection port communicates with said first fluid chamber, and said first partition wall at the front side of said reservoir that divides into said first and said second fluid chambers is positioned proximate the upper surface of said first union hole so that said first union hole is communicated with said first fluid chamber and said second fluid chamber, wherein said second union hole is arranged in said third fluid chamber and said level detector is arranged in one of said second fluid chamber, said third fluid chamber and an area extending over said second and said third fluid chambers; and wherein an opening is formed in an upper portion of said second partition wall at the rear side of said reservoir that divides into said second and said third fluid chambers, so that said second and said third fluid chambers communicate with each other.
