Abstract
A fluid pressure servomotor for automotive vehicle brakes embodying a housing provided by assembling two shells, a pressure responsive power wall in the housing, a valve mechanism associated with the power wall and being movable relative thereto to control the differential pressure across the power wall, an actuating member connecting the pedal for manually moving the valve mechanism, and an output member for connecting the power wall to a brake master piston. The shells are assembled by being locked together and can be disassembled and reassembled due to the provision of a mechanism for resiliently restoring a yieldable portion in a locking structure so that the shells are reassembled by a uniting axial movement and a subsequent rotative movement to lock the shells with each other in position against such resiliency.
