ABSTRACT:
In a control valve assembly operation of inlet and exhaust valves is controlled by a valve-operating assembly which is common to both valves and which is responsive to movement of a piston, and a reversing mechanism incorporated in the valve-operating assembly is constructed and arranged to effect positive movement of a valve in a direction opposite to that in which the piston is being moved axially.
