Abstract: A nozzle 20 has a fluid flow passage 26 which defines a fluid flow path from an inlet 5 end of said passage towards an outlet end of said passage. A restrictor 29a is movable under the control of an actuation system 27 relative to the passage to vary the minimum cross-sectional area of the fluid flow path through the passage. The restrictor 29 is moved to project into the passage to provide a restricted opening in the passage or removed from the passage to allow an unrestricted flow through the 10 passage. The nozzle 20 is particularly suitable for use in a beverage preparation machine to generate microfoam in a beverage. When the restrictor 29 is retracted from the passage 29, the passage and the restrictor can be cleaned by flushing the nozzle. The restrictor 29 may be a pin-like member aligned with the passage and moveable parallel to the axis of the passage.
