摘要： PROBLEM TO BE SOLVED: To surely avoid insufficient lubrication caused by lowering in viscosity of lubricating oil into which refrigerant is diluted, and thereby to improve the reliability of a sealed type compressor. SOLUTION: A bottom part of a high pressure chamber 23 in a casing 20 communicates with a liquid reservoir 31. One end of a communicating pipe 34 is connected with an upper end of the liquid reservoir 31, and the other end thereof is connected with a suction pipe 28. In the middle of the communicating pipe 34, a gas container 35 and first and second solenoid valves 36, 37 are disposed. When the first solenoid valve 36 is closed and the second solenoid valve 37 is opened, the gas container 35 communicates with the suction pipe 28, so that pressure in the gas container 35 is reduced. Then, the the first solenoid valve 36 is opened and the second solenoid valve 37 is closed, the gas container 35 communicates with the liquid reservoir vessel 31, so that pressure in the liquid reservoir 31 is reduced. Therefore, pressure of the lubricating oil in the liquid reservoir 31 is lowered to gasify a refrigerant diluted in the lubricating oil. COPYRIGHT: (C)2005,JPO&NCIPI
摘要翻译：要解决的问题：为了确保避免由制冷剂稀释的润滑油的粘度降低引起的润滑不充分，从而提高密封式压缩机的可靠性。解决方案：壳体20中的高压室23的底部与液体储存器31连通。连通管34的一端与液体储存器31的上端连接，其另一端与吸入管28连接。在连通管34的中间设置有气体容器35和第一和第二电磁阀36,37。当第一电磁阀36关闭并且第二电磁阀37打开时，气体容器35与吸入管28连通，使得气体容器35中的压力降低。然后，第一电磁阀36打开，第二电磁阀37关闭，气体容器35与液体储存容器31连通，从而液体储存器31中的压力降低。因此，储液器31中的润滑油的压力降低，使在润滑油中稀释的制冷剂气化。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a refrigerating device provided with a refrigerant circuit capable of inverting the direction of circulation of refrigerant and capable of stably lubricating a sliding part of a compressor by refrigerant in both of a case where refrigerant circulates in the normal direction and a case where refrigerant circulates in the reverse direction.
SOLUTION: The refrigerant circuit 13 is provided with the compressor 20, an outdoor heat exchanger 14, an expansion valve 15, an indoor heat exchanger 16, and a four way switching valve 17. In the refrigerant circuit 13, the four way switching valve 17 is switched to invert the direction of circulation of refrigerant into the forward or reverse direction and perform cooling operation and heating operation. Here, the refrigerant circuit 13 is provided with a first introduction pipe 31 and a second introduction pipe 32 and a first check valve 41 and a second check valve 42. In cooling operation, high pressure liquid refrigerant after condensed in the outdoor heat exchanger 14 is supplied into the sliding part of the compressor 20 via the first introduction pipe 31. In heating operation, high pressure liquid refrigerant after condensed in the indoor heat exchanger 16 is supplied into the sliding part of the compressor 20 via the second introduction pipe 32.

摘要： PROBLEM TO BE SOLVED: To provide a screw compressor wherein a bearing section of a gate rotor is sufficiently lubricated. SOLUTION: Each gate rotor (50A (50B)) is provided with a shaft part (58) coaxially extending with a rotation axis (X) of the gate rotors (50A (50B)). The gate rotor (50B) in the downward direction is formed such that the part (58) is upwardly extended, while the gate rotor (50A) in the upward direction is formed such that the shaft part (58) is downwardly extended. The gate rotor containing chamber (13) is provided with the bearing part (13b) for rotatably supporting the shaft part (58). The screw compressor (1) includes an oil inducing mechanisms (9, 209, 309) for guiding oil to the bearing part (13b) for at least the gate rotor (50B) in the downward direction.
