Abstract
1,191,030. Spray producers. R. VALFREY. 27 Sept., 1968 [27 Sept., 1967], No. 46071/68. Heading B2F. A fluid diffuser comprises a body 1 which may be attached to a fluid feed pipe by nut 2 and has openings 3 through which the fluid may be supplied to a fixed ring 5 having radial orifices over its entire periphery the fixed ring being surrounded by a rotatable ring 8 also having radial orifices which may be registered with those in the fixed ring, so that the rate of fluid flow may be adjusted by rotating the rotatable ring. The rotatable ring may be formed integrally with a cover 10 which may be secured to the body by screw 11.
