ABSTRACT:
A valve is described capable of rapid actuations. The valve includes a drive element disposed to pinchingly engage a collapsible tube at a high reciprocating speed. A follower is disposed on the other side of the tube and effectively coupled for reciprocation and cooperative movement with the drive element to maintain the tube pinched off. Control means and holder are provided to open the valve by retaining the follower at just that time when the follower is at a favorable reciprocated position so that further reciprocation by the drive element can open the tube. A normally open valve is also described and a control for operation of a plurality of valves is disclosed.
