ABSTRACT:
Time delay apparatus for providing a firing action at the end of a predetermined time-delay period. It is used with a source of fluid under pressure, and defines a fluid-receiving chamber for accumulating the fluid when released from the source. A flow controller is connected between the source and the fluid-receiving chamber for providing fluid communication between the source and the fluid-receiving chamber. A triggering assembly initiates flow of fluid from the source through the flow controller and into the fluid-receiving chamber. A piston-form firing pin in the fluid-receiving chamber is actuated by shear pin release for movement to an actuating position for desired firing action when a predetermined pressure has accumulated in the fluid-receiving chamber at the end of the predetermined time-delay period.
