Abstract
Abstract A sealed type motor-compressor having such structure that a refrigerant gas is directly led from an intake pipe to a cylinder, is described herein. The sealed type motor-compressor is characterized in that between an intake pipe opening within a sealed housing and a gas inlet portion of a cylinder, is provided a connecting member which can slidably follow a relative movement in every direction of an internal component of said motor-compressor.
