摘要： A scroll type compressor has a housing, a fixed metal scroll member and a movable metal scroll member. The fixed and the movable scroll members each have a base plate and scroll wall extending therefrom. The fixed scroll member is fixed to the housing. The movable scroll member engages the fixed scroll member to trace an orbital motion when driven by a crank mechanism. The scroll members define compression chambers. Resin tip seals are respectively provided on distal ends of the scroll walls and slidably engage the metallic surfaces of the facing base plates. The tip seals seal the compression chambers. A resin coating layer is formed on a region of at least one of the end surfaces of the base plates that is not contacted by a tip seal.

摘要： A roots compressor module has a roots compressor accommodating drive (23) and driven (24) rotors in a rotor chamber of a compressor housing, an electric motor( 12) arranged coaxially with the drive rotor and having a motor housing fixedly connected to the compressor housing, a first device (13) supported on one of the compressor and motor housings, a discharge passage (28) formed in the compressor housing and extending from a discharge side of the rotor chamber in a direction perpendicular to an axis of the drive rotor, and a communication passage connecting the discharge passage with the first device or muffler. The first device is located by a side of the electric motor, while the communication passage extends from the discharge side toward a side of the electric motor along the axial direction of the drive rotor, where the axial direction of the drive rotor is defined as a longitudinal direction.

摘要： A roots type fluid machine includes suction and discharge ports, rotary shafts and rotors. A pair of the rotors respectively has a number n of lobe and valley portions with apex and bottom ends for engaging each other. The lobe portions are located on imaginary lines extending radially from an axis of the rotary shaft. The outer surface of the rotor is defined by an outline of the rotor including an arc and involute and envelope curves being rotated and moved in the direction of the axis. The arc has a radius R and a center located on the imaginary line. The involute curve is formed by an imaginary base circle having a radius r and a center located at the axis. The envelope curve is formed by an arc having a radius R. The number n is four or more. A torsional ange β is over 360 / n degrees.
