    Abstract: A servomotor having first and second diaphragm members joined together to form a movable wall. The first diaphragm member is attached to the periphery of the housing of the servomotor and the second diaphragm member is retained by a hub member. The hub member contains a control valve for selectively communicating fluid pressure to one side of the first and second diaphragm members while vacuum is present on the other side in response to an input. When this pressure differential is sufficient to overcome a resilient force acting on the first diaphragm member, a corresponding force is transmitted to the hub member. If the pressure differential is insufficient to overcome the resilient force, the second diaphragm member will expand as the hub member is moved by an input to pressurize a master cylinder while the first diaphragm member remains stationary.

    Abstract: A clip retainer held by a resilient tab in a groove of a hub for limiting the movement of a control valve in the hub and for holding a diaphragm against the hub. Upon actuation of the control valve, fluid under pressure is permitted to flow to one side of the diaphragm. A pressure differential is created across the diaphragm causing the hub to move and transmit a force to an output member.

    Abstract: A partition member for dividing a servomotor into a pair of opposing fluid pressure chambers. A first movable wall having a thickened end adjacent a front shell is fixed to the front end of a hub. A second movable wall having a thickened end which abuts the front shell is fixed to the rear of the hub. The partition member surrounds the hub and compresses the thickened ends of said first and second movable walls into sealing engagement with the front and a rear shell, respectively. A valve member responsive to an operator closes a passage within the hub to create a pressure differential across the first and second movable wall to provide a force to operate a power braking system.
