ABSTRACT OF THE DISCLOSURE A valve for fluid conduits, said valve including two cylinders arranged parallel to each other with their circumferential surfaces in contact, each of said cylinders having a circumferentially extending semi-circular groove formed in the surface thereof the depth of which varies along its length, said grooves defining an aperture through which, in use, fluid is constrained to pass, whereby upon rotation of said cylinders relative to each other the size of said aperture varies to vary the rate of flow of fluid through said valve. The cylinders are rotated in unison in opposite directions by a pair of identical intermeshing pinion gears, one of which is caused to rotate by means of a rack.
