Abstract
For controlling the quantities of supply, waste and recycled air which can be transported by means of a blower (36) for the drying process in a drier (10), this latter comprises a cohesive valve space (38) in which two valve flaps (40 and 42) can be pivoted by a drive. According to the position which the two valve flaps occupy, so the quantities of air supplied and carried away through the apertures (54, 62, 70, 74, 76, 80) in the valve chamber (38) for the drying process are controlled. A third valve flap (44) which can be triggered by a drive controls the process of blowing the washing out of the drier drum (16) after drying. For the sound and heat insulation of the drier (10), a housing (150) in two halves (152 and 154) which covers the blower (36) and the heat exchanger (34) is provided over the valve space.
