Abstract: A low-backpressure rotary compressor includes a shell, a compression mechanism, an oil separator for separating oil and gas from a refrigerant discharged from the cylinder, and an oil pool for collecting a lubricating oil separated by the oil separator. The compression mechanism includes a cylinder assembly, a piston, a sliding vane, main and supplementary bearings. The cylinder has a sliding vane chamber which has an oil supply hole, and a trailing end of the sliding vane stretches into or out of the sliding vane chamber when the sliding vane moves reciprocatingly, such that an interior volume of the sliding vane chamber changes between a maximum volume V2 and a minimum volume V1. The oil pool communicates with the oil supply hole via an oil supply path for the sliding vane, and a ratio of the minimum volume V1 to the maximum volume V2 satisfies the following relationship: 35%≤V1/V2≤85%.

Abstract: A rotatory compressor and a refrigerating cycle device are provided. The rotatory compressor includes a lubricating oil in an interior of a hermetically sealed housing, and an electric motor and a rotatory compressing mechanism disposed in the housing. An internal pressure of the housing is substantially equal to a suction pressure of the compressing mechanism. The compressing mechanism includes a first bearing and a second bearing at least one of which includes an exhaust muffler. A refrigerant of the exhaust muffler flows through the sliding vane chamber and is discharged from an exhaust pipe of the compressing mechanism.

Abstract: A compressor and a refrigeration system are provided. The compressor has a shell, an air cylinder assembly and a pressure relief device. The shell has a containing cavity. The air cylinder assembly is disposed in the containing cavity, and has an air suction cavity and a pressure relief channel. The pressure relief channel communicates with the air suction cavity and the containing cavity, and has a pressure relief opening. The pressure relief device is connected with the air cylinder assembly. The pressure relief device moves in the axis direction of the pressure relief channel, so as to open or close the pressure relief opening.

Abstract: A liquid reservoir, a method for manufacturing the liquid reservoir, and a compressor having the liquid reservoir are disclosed. The liquid reservoir has a barrel, an air inlet tube, an air outlet tube, and a valve. The valve has a partition plate arranged in the barrel. An outer periphery of the partition plate is coupled to an inner peripheral wall of the barrel to divide the internal space of the barrel into an air inlet chamber and an air outlet chamber. The partition plate has a valve hole communicating the air inlet chamber with the air outlet chamber. A limit plate is arranged in the air outlet chamber and at least partially spaced apart from the partition plate. An outer periphery of the limit plate is coupled to the inner peripheral wall of the barrel. The limit plate has a connection hole and a guide hole.

Abstract: A rotary compressor and a refrigeration cycle device are provided. The rotary compressor includes a housing, an exhaust pipe and a suction pipe. The housing accommodates a motor and a compression mechanism. The exhaust pipe is communicated with a high-pressure side of the refrigeration cycle device and coupled to the housing. The suction pipe is communicated with a low-pressure side of the refrigeration cycle device and coupled to the compression mechanism. The compression mechanism has a bypass device. When the motor is stopped, gas of the housing flows into the suction pipe or a low-pressure circuit communicated with the suction pipe.
