摘要： In the hermetically sealed scroll compressor, an injection pipe for injecting a fluid to a compression chamber is connected to an injecting port of a fixed scroll. The injecting port includes a first injecting port which is provided in the vicinity of a fixed scroll inner curve and injects the fluid to an orbiting outer compression chamber, and a second injecting port 22b which is provided in the vicinity of a fixed scroll outer curve and injects the fluid to a orbiting inner compression chamber 8b. The second injecting port is placed in parallel in a radius direction with respect to the first injecting port and is placed so that an orbiting scroll wrap does not practically communicate with the orbiting outer compression chamber in the state in which the orbiting scroll wrap is in contact with the outer side of a fixed scroll wrap.

摘要： In a scroll compressor, an open end of an oil extraction pipe which is placed in oil stored in a bottom portion of a hermetic casing is positioned at a location higher than an open end of an oil suction pipe that opens in the same stored oil, and a thermostat is provided for sensing a temperature rise of a compressed gas to cause the compressor to be stopped. Accordingly, even when an amount of oil injected into the compressed gas decreases, an amount of oil necessary for lubrication of a bearing portion is assured. The provision of the thermostat enables the compressor to be stopped before an amount of supply of the lubrication oil to the bearing portion has decreased. It is, accordingly, possible to positively prevent burning of the bearing portion of a crankshaft.

摘要： A scroll type compressor having a pair of scroll type compression units which are encased in the same casing so as to make a common use of a lubricating oil reservoir provided in the casing, wherein the compression units have compression elements, drive shafts, driving motors and other components which are of the same constructions and specifications, and wherein each of the compression units are adapted to be driven selectively by commercial electrical power or through a frequency-variable inverter so as to operate at different speeds. Since both compression units can be made up from the same components such as the compression elements, loads in the production, service and administration, are greatly reduced contributing to a reduction in the labor and cost, while eliminating any mounting error. Various operation patterns are obtainable by selecting the combination of the direct commercial power and the power supplied through the inverters, so as to provide delicate control of refrigeration capacity over a wide range in accordance with the level of the load demand. Common use of the lubricating oil reservoir by both compression units eliminates necessity for specific measure for preserving oil levels equally for both compression units.
