Abstract: The present invention relates to an in-line electric motor driven compressor station that uses an in-line electric motor driven compressor to transport gas through a pipeline. This station can operate with greater flexibility and reduce costs because either axial or centrifugal compressors can be used, the motor can be immersed in the gas stream or cooled by air, and the station can actually be used to generate electricity. While overcoming the deficiencies of conventional compressor stations, an in-line electric motor driven compressor station offers operators a longer lasting, improved way to maintain the necessary pressures in a gas pipeline.

Abstract: An improved compressor incorporates structure for facilitating the alignment of a suction tube with the motor stator windings. In one embodiment, the motor stator is provided with a protective coating such that the refrigerant entering the compressor housing through the suction tube does not damage the motor windings. In another feature, the chamber housing is bumped out in the location where the suction tube is mounted such that the distance between the radially inner end of the suction tube and the radially outer portion of the windings is increased. The above provides better protection for the motor windings in a sealed compressor wherein the suction tube is axially aligned with the motor windings.

Abstract: In an H/A range in which the ratio H/A≧0.07, where H is the thickness of the bottom wall of a recess (8) provided with a discharge port (4) and a valve seat (9) and formed in the flange (5) of a bearing member (3,3′) and A is the width of the recess (8), the smaller the ratio H/A, the greater is the coefficient of performance (COP). In an H/A range in which H/A<0.07, the COP decreases due to the leakage of the refrigerant resulting from the deflection of the bottom wall of the recess (8) and, eventually, the bearing members (3,3′) are broken. The discharge port (4), the recess (8) and the valve seat (9) are formed so that the ratio H/A≧0.07 and the ratio T/B≦0.3, where T is the thickness of the valve seat (9) and B is the diameter of the discharge port (4). The valve seat (9) can be formed in the thickness T smaller than that of the valve seat of an equivalent conventional compressor, suppressing the deflection of the bottom wall of the recess (8).
