Scroll fan and blower.

Abstract

Scroll machines are being used for air conditioning application. The machines operate under heavy duty conditions. The scroll supercharger which has a rather light application, has also been studied. The authors have found that traction drive with the scroll wrap is possible by rotating the balanced scroll pairs. The machines may be employed for fans and blowers without oil. This type of machine does not require any balance weight, coupling or crank mechanism. Therefore extreme simplification has been achieved. This report presents the concept of the simplified scroll machine and the test results of the prototype.
