摘要

The housing (12) of the heating unit (10) accommodates a rotating shaft (14) provided with a helical elevation (18) arranged along its outer surface and a lever (23), swivel mounted to the housing (12) in a right angle in relation to the rotation axis (16) of the shaft (14). The rotary motion of the shaft (14) is transformed into a swivel motion of the lever (23) by two guide elements moving along the helical elevation (18).
