TH34036B - Two-cylinder rotary compressors - Google Patents

Abstract

DC60 (20/01/48) The invention here is to provide compressors and cycle equipment. Cool, which has a highly reliable rear suppressor construction that prevents gas from making The cold flows back into the cooling cycle due to reverse rotation. of the compressor as soon as the compressor is stopped so as not to cause the mechanical range in The compression has insufficient lubrication due to insufficient refrigerant oil. The two-cylinder rotary compressor consists of a first leveling plate provided in the First cylinder to divide such first cylinder into high pressure chamber and low pressure chamber. and a second leveling plate which was provided on the second cylinder to divide the said second cylinder. It is a high-pressure chamber and a low-pressure chamber, where a spring for pressing the leveling plate is provided. one to the first rolling piston to the first leveling plate while no spring is provided for Press the second leveling plate onto the second rolling piston to the second leveling plate.

Claims (5)

Disclaimers (all) that will not appear on the advertisement page: 1.Two-cylinder rotary compressor that includes two cylinders and two rolling pistons that Are arranged so that they are close to each other in the axial direction within a hermetically sealed container. It consists of: a connecting pipe that is an inlet provided in either of the two cylinders, a connecting pipe that An inlet is used to suck the refrigerant from the outside of the hermetically sealed container to guide the refrigerant. Refrigeration passes through one of the flow channels to the compression chamber of one cylinder; And a separate flow channel that is separated from the first inlet flow channel A second inlet flow channel to guide the sucked refrigerant through a connecting pipe that is Entrance to the compression chamber of another cylinder, through a separate flow channel Where the area of the detached flow channel is defined as larger than the area Flow channel Of the flow channel that is the first inlet 2.Two-cylinder rotary compressor of claim 1 where a non-return valve is provided. For the second inlet flow channel 3.Two-cylinder rotary compressor of claim 1 or 2 consisting of: a connecting pipe that is an inlet provided in either of the two cylinders, a connecting pipe that An inlet is used to suck the refrigerant from the outside of the hermetically sealed container to guide the refrigerant. Cooling passes through one of the flow channels to the compression chamber of one cylinder; And the second inlet flow channel separated from the first inlet flow channel, to guide the sucked refrigerant through the connecting pipe into the compression chamber of the cylinder. Another one Where the second inlet flow channel area is defined as larger The flow channel area of the flow channel that is the first entry channel. 4. A two-cylinder rotary compressor of any 1st to 3rd claim, where the refrigerant It is HFC refrigerant, and refrigerant oil. Is the oil that cannot enter Compatible or almost incompatible with HFC refrigerants. 5.Two-cylinder rotary compressor of claim 4 where HFC refrigerant is R410A or R407C, and refrigerant oil.
