Title: Diaphragm for master cylinder
Inventor: MIZUSAKI YOSHINOBU
IPC: B60T11/26
Filed: 1981-06-09
Abstract: PURPOSE:To imporve the followability of a master cylinder for a car that is provided with a diaphragm in a reservoir and to simplify the shape construction, by bending inwardly upward the lower corners of opposed walls of a box-like diaphragm to form bent sections that can be reversely bent. CONSTITUTION:The edges 7d formed by the bottom wall 7c and a pair of side walls 7b of the box-like diaphragm 1 that is placed to close a liquid supply port of the reservir 1 are bent inwardly toward the upper center of the box so that the reversible bent sections 9 are formed which can be opened toward the opposed walls of the reservoir, following the lowering of the liquid level. In this arrangement, as the working liquid 3 decreases, the reversible bent sections 9 can follow the decrease to be opened toward the opposed walls of the reservoir 1 until they are completely opened to become a box that will be confirmed through a window 11. Thus, the followability against the decrease in the working liquid 3 is better, the level of the working liquid can be precisely confirmed, and the shape structure can simplified.
