Abstract
A motor-compressor unit for refrigerators provided with tubes for feeding the gas from the hermetic container to the cylinder suction chamber. A main tube communicates with the suction chamber by way of the relative silencer, while two supplementary tubes communicate directly with the suction chamber. The configuration and dimensions of the main tube and supplementary tubes have been chosen to obtain a noise reduction without reducing the throughput of the induced gas.
