ABSTRACT:
A timing control circuit for a pneumatically-operable device, which is manually actuable so as to provide fluid flow to a revervoir through means of a variable flow control valve and a line-pressure-operable, normally-open valve disposed within the primary fluid flow, is disclosed. The pressure operable valve is closed at a sensed line pressure so as to interrupt fluid flow to the tool so as to terminate an operating cycle.
