A unit for mixing a first and a second fluid which are at different pressures, provides for the fluid at the lower pressure a first flow path means (4, 6) having a larger cross sectional area than a second flow path means (5, 7) provided for the fluid at the higher pressure, said first and second flow path means directing said fluids to a mixing region (14). The mixing unit includes respective control means (13, 13') which control the flow of said first and second fluids through the separate flow path means into the mixing region 14. The mixing unit also includes elements (13) locked to handles (12) by compressing O-rings therebetween, and a spout (39) mounted in a securing unit (41), for swivelling in use, by a sealing O-ring (47A) located in a groove (44) and an O-ring (47B) located in a groove of greater circumference than that of groove (44) and engaging in a groove in the inner surface of the securing unit. <IMAGE> |
