摘要： A shaft seal device is provided, with which an optimum radial clearance is always maintained between the inner circumferential surface of a carbon ring and an outer circumferential surface of a rotor shaft sleeve when temperature thereof varies in operation of the oil-free rotary compressor, and gas leak through the radial clearance can be suppressed to a minimum not influenced by operation condition of the compressor and intrusion of lubricating oil into the rotor chamber is prevented. As a result, an oil-free rotary compressor can be operated to discharge clean compressed gas not contaminated with lubrication oil. The shaft seal device to be located between the rotor chamber and rotor shaft bearing with a very small radial clearance retained between the inside surface of the shaft seal device and the outer surface of the rotor shaft sleeve 75 fixed to the rotor shaft to restrict gas leak between the rotor chamber and bearing side space is constructed such that the shaft seal device consists of an outer ring 85 and a carbon ring 83 which is fitted into the outer ring 85 with such interference that the interference does not reduce to zero even when they are heated to maximum temperature in operation of the compressor, and the outer ring 85 is made of material having a thermal expansion coefficient coequal to that of the rotor shaft sleeve 75.

摘要： A scroll fluid machine comprises a driving shaft having an eccentric axial portion at one end; a fixed scroll having a fixed wrap; and an orbiting scroll having an orbiting wrap and rotatably mounted to the eccentric axial portion of the driving shaft. A gas introduced through an inlet on the outer circumference of the fixed scroll is compressed by a compression chamber between the fixed and orbiting wraps towards the center and discharged through an outlet close to the center. Between the eccentric axial portion and the innermost winding portion of the fixed wrap, an adiabatic expansion chamber is formed thereby cooling the compressed gas right before discharging.

摘要： A scroll fluid machine has a fixed scroll in a housing and an orbiting scroll rotatably mounted to a driving shaft. A fixed wrap of the fixed scroll is engaged with an orbiting wrap of the orbiting scroll. The orbiting scroll is revolved at a certain eccentricity by the driving shaft, so that a gas sucked through the circumference of the housing is compressed as it moves toward the center, and discharged through the center. A gas-guiding bore is formed near the center of the orbiting scroll, and a heat-releasing rod is inserted in the bore. One end of the heat-releasing rod is projected from the fixed scroll to release heat to atmosphere.
