The same reference numerals in each figure indicate the same or corresponding parts.

Claims (1)

[Scope of utility model registration request] The refrigerant gas sucked from the suction space formed at the outer edge is gradually compressed in the compression chamber formed between the two spirals by combining the spirals, and is then discharged from the discharge pipe formed at the center. and an oscillating scroll, a main shaft that is rotated by a motor and drives the oscillating scroll, a bearing that supports the oscillating scroll and the main shaft, a shell in which the above elements are housed in the upper part and an oil reservoir is formed in the lower part;
A branch space that takes in the refrigerant gas introduced into the shell by the suction pipe, a first passage that communicates the branch space with the suction space, and a cooling space that is formed from the outer periphery of the oil sump upper motor to the upper part of the fixed scroll. , a scroll compressor comprising a second passage communicating the cooling space and the suction space.
