Abstract: The application is directed to a compressor having a housing with a fluid compression region to rotatably support a compressor rotor. The housing includes an inner wall formed as a thin wall positioned about the compression region and an outer wall spaced radially outward of the inner wall. A cooling chamber is formed in a space between the inner and outer walls. A rib formed on the inner wall projects into the cooling chamber to provide structural support and prevent thermal deformation of the thin inner wall during compressor operation.

Abstract: A compression system is disclosed having a compressor and a seal package including a non-contact seal and one or more radial shaft seals. In one form the non-contact seal is placed in proximity to a high pressure portion of the compressor. The offset of the non-contact seal from a shaft used to drive the compressor allows some amount of pressure reduced leakage air to pass. A radial shaft seal is coupled to the shaft axial aft of the non-contact seal on the other side of the compressor and oriented to discourage further passage of the leakage air past the radial shaft seal. A vent conveys leakage air to return to the compressor. A backup radial shaft seal can be used axially aft of the first radial shaft seal. A further radial shaft seal is disposed adjacent to the backup seal and oriented in the other direction to seal lubricant for a bearing.

Abstract: Devices, systems, and methods for pulsation dampers for compressors include outer and inner chambers forming parallel flow paths.

Abstract: An aspect of the present disclosure includes a compressor system operable for compressing a working fluid. An integrated muffler and pressure pulse dampener (IMPPD) is operable for reducing pressure pulsations and attenuating noise in the working fluid. The IMPPD system includes an elongate axial passageway bounded by an outer wall having a plurality of apertures extending therethrough. A first portion of the working fluid enters through the central elongate section and a second portion of the working fluid passes through the pertures. The first and second portions of working fluid merge together downstream of the IMPPD inlet and cause a dampening of pressure pulsations propagating within the working fluid.
