<P>PROBLEM TO BE SOLVED: To sufficiently protect a compression mechanism against high-temperature damage, in a high-low pressure dome type compressor. <P>SOLUTION: In the high-low pressure dome type compressor (2), an inside of a casing (10) is partitioned into a lower side high-pressure space (28) and an upper side low-pressure space (29) with the compression mechanism (15) therebetween, and a motor (16) is arranged in the high-pressure space (28). The compression mechanism (15) is formed with a compression chamber (40), a delivery port (41), a chamber room (45), and a communication flow passage (46). The chamber room(45) is partitioned from the low-pressure space (29) by a chamber cover (44) positioned in an upper side of the delivery port (41). A thermovalve (21) is provided in a just upper portion of the delivery port (41) in the chamber cover (44), to communicate the low-pressure space (29) with the chamber room (45), when reaching a prescribed valve operation temperature. <P>COPYRIGHT: (C)2013,JPO&INPIT |
