ABSTRACT:
A fluid control valve of the kind in which a pair of cylindrical rollers (26,27) are provided with complementary peripheral grooves (32) the cross-section of which is tapered so as to form an aperture the size of which is varied by rotation of the rollers. For sealing the rollers within a chamber formed by a valve liner (34,35) the cylinder peripheries are provided with oppositely inclined sealing teeth (43,44) and resilient sealing projections (43) which engage in the closed position of the valve. Complementary ramped formations (46,47) are provided on the lining and ends of the rollers.
