ABSTRACT:
A pneumatic servo booster includes a shell housing consisting of front and rear shells, a valve body slidably extending through the rear shell, a flexible diaphragm cooperating with the valve body for partitioning the interior of the shell housing into front and rear chambers, a plunger connected to an input rod and being slidably fitted in the valve body, a valve mechanism including a poppet valve and two valve seats which are formed respectively on the valve body and the plunger, and at least one rigid rod secured respectively to the front and rear shells and extending through the front and rear chambers. The valve mechanism communicates the two chambers when the poppet valve is spaced from the valve seat of the valve body and is seated on the valve seat of the plunger. A return movement restricting member is slidably mounted on the rigid rod and engages with the plunger, and resiliently restricts the return movement of the plunger at the end of the return stroke of the input rod.
