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: On a plane orthogonal to the rotation shaft, an upper muffler chamber has a plurality of flared portions that are flared from a center of a rotation shaft toward between penetrating bolts and a plurality of small-diameter portions that connect between the flared portions, are apart from penetrating bolts, and are formed on a center side of the rotation shaft from the penetrating bolts. A muffler outlet is provided in each flared portion. A second outlet and a refrigerant path hole of an upper end plate are positioned on an inside of one of a plurality of flared portions, and an opening area of the muffler outlet of one flared portion is greater than an opening area of the muffler outlet of each of the other flared portions.

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.
