摘要： In a double toothed type scroll compressor, spiral wraps are formed on both sides of an end plate of an orbiting scroll, and wraps adapted to engage with the spiral wraps are formed on a stationary scroll. A dust wrap is formed on a side diametrically outside of the wrap of the stationary scroll. Grooves are formed on ends of the respective wraps to receive therein seal members formed of a high polymer material. Electric charge of static electricity produced when the seal members slide on surfaces of the mating end plate is made to flow from a bolt provided on an end of a crankshaft to the stationary scroll through a brush, thereby preventing accumulation of electric charge in a crankshaft.

摘要： An oil-free scroll compressor used for compression of air or the like, comprises an orbiting scroll having a spiral-shaped lap or laps formed on one or both sides of an end plate, and a stationary scroll having a lap or laps adapted to mate with the orbiting scroll to define a compression chamber or chambers.Grooves are formed on tips of the respective scroll laps, and elastic tip seals are fitted into the grooves in order to prevent leakage of compressed gas from between the laps and the end plates. Those surfaces of the orbiting scroll and of the stationary scroll or scrolls, which define the compression chamber or chambers, are subjected to surface treatment in order to prevent seizure or the like caused by sliding of the tip seals and the laps. The stationary scroll or scrolls are subjected to an anodizing coating treatment while the orbiting scroll is subjected to Ni--P--B treatment.

摘要： A high reliability water injected scroll air compressor is provided with an orbiting scroll, a fixed scroll corresponding to the orbiting scroll, a motor that generates driving force for making the orbiting scroll orbit the fixed scroll, a compressing path from a suction port to a discharge port, and a portion for injecting water into the compressing path. The operation is controlled by a switching operation in which water is injected into the compressing path and then no water is injected. Corrosion, failure of activation, and concerns about wrap contact when water is injected into an air end are avoided by switching the operation with water injection and the operation without water injection so as to prevent water from remaining in the air end.

摘要： A double scroll compressor including an orbiting scroll having spiral wraps formed on both sides of an end plate includes two stationary scrolls, each having a wrap formed thereon to mesh with the corresponding one of the spirals to form a compressing flow passage. The power of a driver, such as a motor, is transmitted via pulleys to two crank shafts which are disposed to extend through the end plate of the orbiting scroll approximately symmetrically with respect to the end plate. The two crank shafts are synchronously rotationally driven by a timing belt disposed between the pulleys. While the crank shafts are making their rotary motions, the orbiting scroll makes its eccentric circular motion and a sucked gas is compressed between the orbiting scroll and the stationary scrolls. A multiplicity of cooling flow passages approximately perpendicular to a line which connects the axes of the crank shafts are formed to extend through the central portion of the end plate of the orbiting scroll. The heat generated in the meshed portion between the orbiting scroll and the stationary scrolls is carried to the outside of the compressor by cooling air which flows through the cooling through-passages.

摘要： A cooling fan is fitted to one of the shaft end portions of a double-end motor, and a pulley is fitted to the other end portion. A belt is passed around this pulley and a pulley fitted to a compressor element, and the compressor element is driven by this belt. The compressor element is disposed in such a manner as to be stacked up in an upward direction of the motor. An exhaust duct having a built-in cooler is also disposed in such a manner as to be stacked up above a cooling fan on the discharge side of the cooling fan. A main duct is formed on the suction side of the cooling fan and is interconnected in series with a cooling air outlet of the compressor element. These members described above are accommodated inside a casing. Therefore, two cooling air flow passages are defined on the right and left sides inside the casing.
