Abstract
A motor driven fluid compressor having compression and drive mechanisms within a hermetically sealed housing is disclosed. The compressor includes the compression mechanism, and the drive mechanism. A drive shaft and a motor rotates the drive shaft. A hermetically sealed housing contains the compression mechanism and the drive mechanism. The drive shaft is operatively connected to the compression mechanism, and is rotatably supported by a first inner block and a second inner block which is axially spaced from the first inner block. The first and second inner blocks are integral with first and second portions of the housing, respectively. As a result, the longitudinal axis of holes formed within the first and second inner blocks and the longitudinal axis of the compressor housing are easily and precisely aligned without increasing in the manufacturing cost.
