Abstract
A fluid control device includes a housing providing a fluid inlet and fluid outlet and a passage extending therebetween. The passage has a longitudinally extending tapered portion which narrows in the direction towards the inlet, and a fluid flow control member located in the passage and having a tapered end corresponding to the tapered portion of the passage. The fluid flow control member is movable longitudinally within the passage between a first position, in which the tapered end of the member engages the tapered portion of the passage and fluid flow along the passage towards the inlet is prevented, and a second position in which fluid flow along the passage is possible.
