Abstract (en)
The invention is directed to a reflective muffler (100) for reducing noise level in an exhaust line of an air-processing unit. The muffler comprises an input port (102) and an output port (104) for exhausting exhaust air (106b). A damping unit (107) is arranged between the input port (102) and the output port (104) and comprises a damping chamber (108) including at least one flow-deflection element (110) that is configured to block a direct flow path (112) between the input port and the output port, and an inlet chamber (114) arranged between the input port and the damping chamber. The inlet chamber is separated from the damping chamber by a first separation wall (122) having a pneumatic orifice (124). The inlet chamber has a cross sectional area value (CS1) perpendicular to a longitudinal direction (L) that increases in a flow direction (F) from the input port to the damping section.
