Abstract
Reduction of noise produced by hermetic compressors. The acoustic filter includes an inlet duct, an outlet duct and a main chamber. The inlet duct includes a refrigerant fluid inlet and a refrigerant fluid delivery end. The refrigerant fluid delivery end is opposite to the refrigerant fluid inlet and it is capable of guiding the refrigerant fluid to the main chamber. The outlet duct includes a refrigerant fluid outlet and a refrigerant fluid collection end. The refrigerant fluid collection end is opposite to the refrigerant fluid outlet for guiding the refrigerant fluid from the main chamber to the fluid outlet. The filter includes a resonator chamber arranged adjacent to the inlet duct and adjacent to the main chamber. The resonator chamber and the inlet duct are fluidically connected by a resonator tube and the resonator chamber is separated from the main chamber by a sealing wall.
