Abstract
A high working pressure air sequencer has a manifold to which are connected a high pressure air inlet and a plurality of outlets to which high pressure air is to be distributed. A rotary valve head is located within the manifold, and sequentially couples the air inlet to a different outlet. The valve head includes an outlet button which includes a bore which sequentially aligns with the outlet bores. Both the outlet button bore and the outlet bore portions with which the button bore aligns are of geometries which provide a rapid transition between coupled and uncoupled air passage conditions.
