Acoustic filter for compressor

Acoustic filter for compressor comprising:

• an inlet duct, an outlet duct and at least one main chamber, wherein
• the inlet duct comprises a refrigerant fluid inlet and a refrigerant fluid delivery end, wherein the refrigerant fluid delivery end is opposite to said refrigerant fluid inlet and it is capable of guiding the refrigerant fluid to the main chamber;
• the outlet duct comprises a refrigerant fluid outlet and a refrigerant fluid collection end, wherein the refrigerant fluid collection end is opposite to said a refrigerant fluid outlet and it is capable of guiding the refrigerant fluid from the main chamber to said fluid outlet,
• the filter being characterized by the fact that it comprises a resonator chamber arranged adjacent to the inlet duct and adjacent to the main chamber, wherein the resonator chamber and the inlet duct are fluidically connected by at least one resonator tube and the resonator chamber is separated from the main chamber by a sealing wall;
• wherein the at least one main chamber comprises a bottom, side walls, and an upper wall, wherein one of the side walls is the sealing wall, wherein between the end of the sealing wall and the bottom of the main chamber the delivery end of the inlet duct is arranged, and that it further comprises a valve seat arranged adjacent to the refrigerant fluid delivery end and a valve control arranged in the upper wall of the at least one upper wall of the main chamber.
