发明名称 MASTER CYLINDER
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a master cylinder capable of conducting a smooth operation of connection equipment without causing a high rise of product cost by eliminating the insufficiency of a working fluid in a pressure chamber by a simple structure. <P>SOLUTION: A bypass passage 36 for connecting a reservoir 2 and the pressure chamber 6 is formed, and a cylinder 33 is formed in the bypass passage 36. In the cylinder 33, a bulkhead piston 39 for partitioning the inside into a storage chamber 38 and a back pressure chamber 37 is slidably stored. The bulkhead piston 39 is energized by a coil spring 40 in the direction of the back pressure chamber 37. When the pressure chamber 6 is lowered to set pressure or higher in relation to the reservoir 2, the bulkhead piston 39 is operated and the working liquid in the storage chamber 38 is supplied. <P>COPYRIGHT: (C)2009,JPO&INPIT</p>
