Abstract

In a reciprocating air operated pump having pumping elements which reciprocate along a first axis, an air valve comprising: a valve carriage moveable along a second axis normal to the first axis; a valve block moveable in the valve carriage along the first axis; a valve surface comprising first and second main ports; first and second pilot ports and an exhaust port; means for causing the valve block to move as the pumping elements move; and means for supplying compressed air over the valve surface and in which the valve block moves in a generally planar rectangular path between four positions, in which in each of the positions, the valve block connects a main port, a pilot port and the exhaust port.
