| 摘要 |
The present invention refers to a noise muffler for refrigeration compressors capable of dampening noise generated by the intermittent flow of the compressor and at the same time a muffler that reduces the loss of load in the refrigeration system. Accordingly, a noise muffler for a refrigeration compressor (1) is described, the muffler (1) including at least one suction chamber (2), the suction chamber (2) including at least one flow entry channel (3), the suction chamber (2) including at least one flow exit channel (4), the suction chamber (2) including at least one directional duct (5), the directional duct (5) including at least one first end (70), the directional duct (5) including at least one second end (80), the directional duct (5) including at least one flow control means (300), the first end (70) including an area substantially greater than the second end (80), the first end (70) being associated to the flow entry channel (3), the second end (80) being associated to the flow exit channel (4), the directional duct (5) being capable of directing a preferred flow (200) received at the first end (70) to the second end (80), the flow control means (300) being capable of offering reduced resistance to the passage of the preferred flow (200) and being capable of offering resistance in the opposite direction to the passage of the preferred flow (200).
