Abstract

A gas or vapour pump comprising a compressible piston slideably accommodated in a bore in a housing wherein the cross sectional area of the bore and the piston decreases towards an outlet of the pump. The decrease in bore produces a reduction in the force required to move the piston. <IMAGE>
