Abstract

A flow control device (10) for adjusting the rate of flow of a pressurised liquid. The device (10) comprises an elongate body (15) defining an inlet (11) for receiving liquid under pressure, one or more aperture (18) through which liquid may pass, and a flow path from the inlet (11) to the or each aperture (18). The device (10) includes a resilient sheath (19) mounted around the body (15) to close the or each aperture (18). The sheath(19) is expandable in response to increases in the pressure of the liquid to open the or each aperture (18) and to define an outlet (13) between the sheath (19) and the body (15). This permits the liquid to flow out of the or each aperture '(18) and be ejected from the outlet (13). The rate of flow is directly proportional to the pressure of the liquid introduced to the inlet (11), such that an increase in liquid pressure increases the size of the outlet (13), resulting in an increase in flow rate.
