Abstract
A multi-layered compressor housing and method of manufacture is provided. The housing defines an interior space and includes first and second layers having first and second major surfaces respectivley. The first and second layers are secured together by the frictional engagement of the first and second major surfaces which each substantially enclose the interior space defined by the housing. The housing may be manufactured by placing first and second layers of sheet stock material in mutual facing engagement wherein the two layers are relatively moveable. The first and second relatively moveable layers are then simultaneously formed into a non-planar shape defining at least a portion of the housing. A compressor is then mounted in the housing and the housing is hermetically sealed. The simultaneous forming of the first and second layers into a non-planar shape causes the frictional engagement of the layers whereby the layers are secured together.
