Abstract

The pump comprises a chamber with inlet and outlet (20, 24, 25) for a first fluid or gas, which is delivered in measured quantities under the effect of a second fluid or gas delivered by impulses into a second chamber (21), also with inlet and outlet. The two chambers are sealed off from each other by a flexible diaphragm (23). Where gas and liquid are to be mixed, liquid can be handled by the first chamber and gas by the second, the liquid being vapourised in the process before mixing the two together. In this case the liquid flow can be kept constant, whatever the impulses delivered by the gas, typically using a vertical rod anchored to the diaphragm centre and working in guides. Stops restrict the amount of rod movement, and these can be adjustable.
