Brake master cylinder housing |
摘要 |
A process for the manufacture of a master cylinder for hydraulic brake units of automotive vehicles. The starting material is a pasty material which is between solid and liquid. In the course of the casting procedure, thin material wall thicknesses are created in the regions of intended openings of the master cylinder, such as the breather bore (14) and the intake bore (5). The floating membrane (12) which forms during the casting process is removed by mechanical machining to open the duct which functions as the intake bore. The breather bore (14) which functions as the compensation bore is formed by a stamping operation. |
