The new lightweight DA-6 Automotive Air Conditioning Compressor and Clutch Assembly is the lightest weight, most versatile 164 cc displacement compressor available today. It was designed and developed by General Motors which has produced over 72,000,000 compressors beginning with a 26.3 Kg rotary in 1953. In 1961, the 15.1 Kg six cylinder axial design was introduced and still remains a standard for the industry. A lighter weight 8.1 Kg radial four started production in 1974 and in 1982 the lightweight 5.7 Kg DA-6 will be introduced.
Features of the mechanism include:
A unique lubrication system
High strength piston design in conjunction with a special TFF ring eliminates the need for cylinder sleeves
An integral wide band gas pulse attenuator eliminates external mufflers
Smooth torque pulses simplify construction and reduce weight of the mounting bracketry; also eliminates the need for torque dampeners, inertia rings, and idler pulleys
Optional direction of rotation
Mounting arrangement may be rotated to provide more flexible application
Mountings in the rear head provide for system control switch application.
The clutch is a lightweight electromagnetic six-pole design that provides for a small diameter poly-vee pulley as well as a single “V” groove. The distance from the pulley to the front of the compressor is short which is an advantage when the compressor is mounted on an engine and bottom loaded into a car.
