摘要： A screw compressor for acoustic resonance reduction and refrigeration systems including the screw compressor are disclosed. The screw compressor has an acoustic barrier integral with the compressor housing for use with a slide valve assembly that includes a piston connected to a slide valve. A shaft connecting the slide valve and the piston passes through an aperture in the barrier with the piston and the slide valve disposed on opposite sides of the barrier. The acoustic barrier protects the piston from discharge pulses of compressed fluid exiting the rotors of the screw compressor, thus attenuating acoustic resonance, reducing compressor noise and premature wear of the slide valve assembly and compressor housing.
摘要翻译：公开了一种用于包括螺杆式压缩机的声共振减少和制冷系统的螺杆式压缩机。螺杆式压缩机具有与压缩机壳体一体的声屏障，用于与滑阀组件一起使用，滑阀组件包括连接到滑阀的活塞。连接滑阀和活塞的轴穿过阻挡件中的孔，活塞和滑阀设置在屏障的相对侧上。声屏障保护活塞免受从螺杆压缩机转子排出的压缩流体的排出脉冲，从而衰减声共振，减少压缩机噪音和滑阀组件和压缩机壳体的过早磨损。

摘要： Sound attenuating liquid-gas separation apparatus includes nested elements which are tuned to abate noise in general and at predetermined frequencies in particular in a screw compressor assembly. The apparatus includes a helical flow path defined internal of an outer shell. The shell is selectively perforated at its downstream end to allow for the egress of separate oil from it. The apparatus includes a columnar, open-ended cylindrical member internal of the outer separator shell and a discharge conduit which penetrates both the separator shell and the open end of the columnar cylindrical member disposed within the shell to create the nesting which both contributes to the oil separation proces and abates noise. By selectively dimensioning and therefore "tuning" the nested members in accordance with the characteristics of the particular compressor with which they are used, compressor assembly noise abatement at predetermined frequencies is accomplished.

摘要： A rotary compressor for refrigerating apparatuses, including a motor unit, a compressor mechanism section including a cylinder, rotary piston in the cylinder and a bearing between the motor unit and the cylinder, and a discharge muffler. The discharge muffler is formed of a diaphragm and a discharge cover placed over a surface of the bearing opposite the motor unit, the surface of the bearing covered by the diaphragm having a concavity therein housing a valve leading to the cylinder. The diaphragm has a permanently open diaphragm hole for permitting the pressurized gas therein to flow into a discharge chamber defined between the diaphragm and the discharge cover, whereby the portion of the concavity not filled by the valve and the diaphragm define a muffler for muffling sounds of the compressor.

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.
