Abstract
A nozzle arrangement comprises a body (10) of two parts (11), (12) which define between them a fluid passage (15), leading to a discharge outlet (25), from a feed passage (17). The passageway contains a chamber (19) wherein is located a flap member (20) which can be displaced by increased pressure of fluid flow in the passageway to variably obstruct an outlet orifice (21). This may be achieved by the cooperation of holes or notches in the displaceable flap member and corresponding apertures or notches in a fixed member.
