Abstract
The scroll type compressor has a hermetic casing, and a scroll compressor section and an electric motor section which are contained within the hermetic casing. These compressor and electric motor sections are fitted through a frame in the hermetic casing. In a portion of the frame intermediate between the compressor and the electric motor section, a plurality of segmented concave spaces are defined. At an upper portion in the hermetic casing, a discharge space which communicates with a discharge port of the scroll compressor section is defined. Further, in a portion of the casing between the compressor and the motor section, a delivery port which open to one of the concave spaces in the frame is provided. Furthermore, at least one fluid passage is provided in an outer periphery of the compressor section and this passage makes the discharge space communicate with the other concave spaces in the frame. A compressed gas from the scroll compressor section is introduced via the discharge space and the fluid passage into the concave spaces, and is introduced from the delivery port to the outside of the compressor after separating the oil contained within the compressed gas in these conca…
