Abstract
This apparatus includes a housing defining within it a first conduit having at least one internal bulkhead extending partially within a distribution chamber and at right angles to the pivot axis of a distribution valve so as to define at least two adjacent air outlets. The housing also defines within it a second conduit having a further air outlet. The distribution valve comprises vanes which are offset axially and circumferentially from each other, for selectively controlling the distribution of air through the outlets of the first conduit, together with a vane for controlling the distribution of air through the outlet of the second conduit.
