Abstract
A fluid actuated pilot assembly employing a cantilevered spring member which is mounted to apply a force to a sensing piston in opposition to the force applied by the sensed fluid pressure. Upon the occurrence of the pressure of the fluid being sensed exceeding the force of the cantilevered spring member, the sensing piston is moved to initiate a control function.
