Abstract

The valve (25) comprises a casing (27) with at least three openings (29, 31, 35) for air to flow in and out, containing at least one throttle plate (39) with two sides (41, 43) surrounded by a frame (45). Rotating the frame about an axis (47) allows it to adopt a first position in which the plate is next to a first section (49) of the casing so that air can flow between the first and second openings, or a second position in which the plate is next to a second section (53) of the casing so that air can flow between the first and third openings. A seal is provided for sealing the space between a first side of the plate and the first casing section when the plate is in the first position.
