    摘要: According to one embodiment, a rotary compressor includes a compression mechanism unit. The compression mechanism unit includes at least three cylinder bodies interposed between a first bearing and a second bearing, a plurality of partition plates provided between adjacent cylinder bodies, and a plurality of rollers compressing a working fluid in cylinder chambers of the cylinder bodies, and at least three cylinder chambers are partitioned by an end plate of the first bearing, an end plate of the second bearing, and the partition plates. Each of the end plates includes a first discharge port discharging the working fluid to a muffler chamber. Each of a plurality of partition plates includes an intermediate muffler chamber, and a second discharge port discharging the working fluid.

    摘要: The disclosure relates to a compressor having a noise reduction resonator. The compressor includes: a compression part having compression space in which introduced gas is accommodated, and configured to compress and discharge the gas in the compression space; and a gas moving part having an inner wall forming a gas flow path through which the gas discharged from the compression space moves, wherein the gas moving part is provided with a first resonator configured to communicate with the gas flow path on the inner wall forming the gas flow path and having a resonance space depressed upward in a moving direction of the gas. The compressor according to the disclosure may prevent compression efficiency from decreasing and maintain a noise reduction effect for a long period of time by preventing foreign objects or liquids from being accumulated in the resonance space.

    摘要: A compressor includes a compression chamber forming member, an injection passage, an injection pipe, and a pulsation attenuation space. The compression chamber forming member forms a compression chamber. The injection passage is formed in at least one of the compression chamber forming member and a separate member disposed in a surrounding area and connecting to the compression chamber. The injection pipe supplies refrigerant to the injection passage. The pulsation attenuation space is formed in one of the compression chamber forming member and the separate member disposed in the surrounding area so as to communicate with the injection passage. The pulsation attenuation space attenuates pulsation of refrigerant gas flowing from the injection pipe into the compression chamber.

    摘要: A device (DV) for damping pressure fluctuations in a pressure medium (DM) comprises the following features. It has a base body (GK) in which an intake chamber (AK11) is provided, which has an intake-chamber opening (OA1) which is located at a first side (S1) of the base body. A first expansion chamber (EK11) is furthermore provided in the base body, which has a first expansion-chamber opening (OE1), which is likewise located at the first side of the base body. A partition wall (T1) separates the intake chamber from the first expansion chamber. A cover element (AD) for positioning on a contact surface (AF) of the first side of the base body is furthermore provided in order to close the intake chamber and the first expansion chamber to the outside. Finally, an overflow channel is provided, in particular in the partition wall between the intake chamber and the first expansion chamber, so that pressure fluctuations in the pressure medium are damped during the through-flow from the intake chamber through the first overflow channel into the first expansion chamber.
