Abstract

See full text

A servo mechanism for a vehicle braking system comprises a pressure housing having a front shell 2 and a rear shell 3. A tie rod 43 passes through the front and rear shells 2 and 3, and also through a power piston 4 and diaphragm 5 within the pressure housing. One end of the tie rod carries a device to be actuated by the servo mechanism, while the other end of the tie rod is secured to a vehicle body. In order to provide a fluid-tight seal around the tie rod, a boot 53 is provided, having one end 53a secured to the tie rod 43, and the other end 53c secured within a hole 4a in the piston 4. A cylindrical securing member 54 clamps the respective end 53c of the boot 53 within the hole 4a in the piston 4, and also serves to clamp together the diaphragm 5 and piston 4, in the region of their respective holes 5a and 4a through which the tie rod 43 passes.
