<p>#CMT# #/CMT# The heating or climate control unit, especially for a motor vehicle, has a housing accommodating a first and/or a second heat exchanger, and a drum valve (7) serving as a mixing valve which is installed in a mixing chamber after the first and/or second heat exchanger in the region of the inlet of a first and second air duct. The drum valve in the region of at least one longitudinal edge (16) of its partial hollow cylindrical section (15) has a protruding section (17) which in the end position of the drum valve covers a passage lying upstream of the mixing valve between the first and second air ducts. The first heat exchanger is an evaporator and the second a radiator. #CMT#USE : #/CMT# The heating or climate control unit is especially for a motor vehicle. #CMT#ADVANTAGE : #/CMT# The heating or climate control unit is improved with regard to the mixing of colder air coming from the evaporator or outside air supplied by a fan, and warmer air coming from the radiator, with the smallest possible mixing chamber. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a drum valve according to the invention. 7 : drum valve 13 : pivot axis 14 : circle segment 15 : hollow cylindrical section 16 : longitudinal edge of hollow cylindrical section of drum valve 17 : protruding section.</p> |
