ABSTRACT:
A servomotor having a front shell with an annular wall in which an annular groove is located adjacent to an open end thereof. A rear shell has a peripheral ledge with radial lugs which are aligned in slots on the annular wall of the front shell. A diaphragm secured to a hub, which can move within the annular wall, has a bead with a contour which matches the annular wall from the annular groove to the slots. The peripheral ledge on the rear shell engages and compresses the bead of the diaphragm against the annular wall and groove of the front shell to separate a front chamber from a rear chamber when tabs on the open end of the annular wall lock the lugs against the slots.
