Abstract
A control valve arrangement for a pressure differential operated servomotor wherein a key member is located in a slot in a hub to retain the control valve and position the control valve in a position to isolate a first chamber from a second chamber in the absence of an input force being applied to operate the valve. The control valve in response to an input force immediately moves to initiate the development of the pressure differential and as a result substantially eliminates the operational time to effect a brake application.
