ABSTRACT:
A sequencing valve for use in a pneumatic program controller has two output ports in rotors on a common driving shaft which may be moved intermittently for moving such output ports into line with circles of output ports in stators, in which the rotors are placed. The stator output ports are regularly spaced. The two rotor output ports or the groups of stator ports in the two stators are out of line with each other by half the pitch of the ports in the stators.
The intermittent driving motor has a rocking fork for turning a toothed wheel on the driving shaft. The fork is mechanically locked in its two half-step positions by way of a stop pin which is moved by a bellows actuator against the force of a spring so that a stop collar on the pin may be moved into and out of the way of the rocking fork.
