摘要： A compressor includes a bore, a rotor disposed within the bore, a compressor inlet, and a compressor outlet. The compressor further includes a compression chamber defined between the bore and the rotor, wherein a volume of the compression chamber gradually reduces from the compressor inlet to the compressor outlet. The compressor includes an economizer. The economizer is fluidically connected to the compression chamber. The economizer is configured to inject a working fluid into the compression chamber at an injection position. The injection position is changeable according to a working condition of the compressor.

摘要： A compressor may include a shell, a compression mechanism, first and second temperature sensors, and a control module. The shell may define a lubricant sump. The compression mechanism may be disposed within the shell and may be operable to compress a working fluid. The first temperature sensor may be at least partially disposed within the shell at a first position. The second temperature sensor may be at least partially disposed within the shell at a second position that is vertically higher than the first position. The control module may be in communication with the first and second temperature sensors and the pressure sensor and may determine whether a liquid level in the lubricant sump is below a predetermined level based on data received from the first and second temperature sensors.

摘要： A compressor includes a rotor having an outer compression surface and a plurality of inner heat exchange surfaces. A coolant supply manifold fluidly connects with a coolant inlet in a first axial end of the rotor, and delivers coolant fluid by way of conduits having an axial distribution in the rotor so as to deliver coolant fluid to the heat exchange surfaces. The coolant may be a refrigerant that undergoes a phase change within the rotor.

摘要： The present invention provides a PFA resin helical blade for use in a compressor, which is superior in dimensional precision and surface smoothness with a superior anti-fatigue property, and a manufacturing method thereof. In a manufacturing method of a compressor-use helical blade of the present invention, a PFA composite resin, which is formed by mixing an inorganic filler with a tetrafluoroethylene/perfluoroalkylvinyl ether copolymer (PFA resin) having a nullCH2OH terminal group, which has not been subjected to a stabilizing process, and has fluidity of not ness than 15 g/10 min, is used, and after the resin has been molded into a helical blade through an injection-molding process, the resulting matter is subjected to a heating process at a temperature from 280 to 300null C. for a period from not less than 10 hours to not more than 300 hours. The compressor-use helical blade, made of the PFA composite resin by using the above-mentioned method, is allowed to have an increased molecular weight of not more than 10 g/10 min represented as an MFR (melt flow rate) value.

摘要： A helical-blade fluid machine maintains a low-pressure atmosphere in a closed casing (1) and secures a proper lubrication state for a compression mechanism (9). The fluid machine has a drive mechanism (7) that is installed at an upper or lower part of the casing and consists of a stator (11) and a rotor (15). The compression mechanism is installed at the other part of the casing. The compression mechanism has a cylinder (23) and a roller (25), which is swayed with respect to the cylinder by the drive mechanism. A helical blade (39) having unequal pitches is arranged on the roller, to define compression chambers (41). This arrangement lowers the head of lubricant. An intake pipe (5) feeds gas into the casing so that a low-pressure atmosphere fills the casing.
