Abstract: A structure for sensing refrigerant flow rate in a compressor. The structure includes a passage forming member, a restriction hole, a differential pressure-type flow rate sensor, and a partition plate. The compressor includes a housing connected to an external refrigerant circuit via a refrigerant passage. The passage forming member is connected to an outer surface of the housing and forms a part of the refrigerant passage. The restriction hole divides the refrigerant passage into an upstream passage and a downstream passage. The upstream passage is formed in either the housing or the passage forming member. The sensor is provided in the passage forming member and detects pressure in the upstream passage and pressure in the downstream passage to sense flow rate of refrigerant in the refrigerant passage. The partition plate is disposed between the housing and the passage forming member. The restriction hole is formed in the partition plate to extend through the partition plate.

Abstract: The compressor is provided with an oil separator for separating oil from refrigerant gas introduced into a separation chamber, an annular space for reserving oil separated from the refrigerant gas, and a reservoir chamber for reserving the thus separated oil. The oil separator is provided in a cylindrical hole formed in a discharge chamber from which the refrigerant gas is discharged and a lid for partitioning the cylindrical hole from the discharge chamber is provided in the cylindrical hole. The oil separator introduces the refrigerant gas from the discharge chamber to the separation chamber via the introduction passage. The annular space is provided around the lid and connected to the reservoir chamber via an oil passage. The reservoir chamber is connected to a crank chamber of a pressure lower than that in the discharge chamber.

Abstract: A compressor connected to an external refrigerant circuit is disclosed. The compressor is provided with a housing, a passage forming member coupled to an outer surface of the housing, and a differential pressure type flow rate detector provided in the passage forming member. The flow rate detector obtains the pressure in an upstream passage and the pressure in a downstream passage to detect a refrigerant flow rate within the refrigerant passage. The flow rate detector is provided with an accommodation chamber, a partition body, a compression spring, and a spring seat defining a maximum stroke amount of the partition body. The spring seat exists closer to the passage forming member side than a partition surface comparting the housing and the passage forming member, and is in contact with the partition surface.
