Method of fastening a first shell to a second shell to form a sealed housing.

摘要

A method of fastening a first shell (10) to a second shell (12) to form a housing by crimping an annular wall (72) of the former over a radial flange (24) of the latter to axially compress therebetween a head (30) of a diaphragm (32) which is received within a circumferential groove adjacent said radial flange, thus sealing the interior of the housing from the surrounding environment.

According to the invention, the annular wall (72) of the first shell (10) isifurther deformed as at (76) to radially compress the bead of the diaphragm into the groove of the second shell (12).

For use particularly in the production of pneumatic servomotors for power braking systems.
