Abstract (en)

[origin: WO2012055900A1] The invention relates to a silencer device (10) for a fluid line (12), having a resonator arrangement (14) which comprises a first resonator tube (16) with a first resonator chamber designed for ?/4 damping of at least one sound wavelength, wherein the first resonator tube has a first longitudinal direction, two end walls (31, 33) situated opposite one another in the first longitudinal direction, and a first side wall (23) which extends between the end walls, and wherein the first resonator chamber is formed between the first side wall and the end walls (31, 33) of the first resonator tube (16). The resonator arrangement (14) further comprises a second resonator tube (18) with a second resonator chamber designed for ?/4 damping of at least one sound wavelength, wherein the second resonator tube has a second longitudinal direction, two end walls situated opposite one another in the second longitudinal direction, and a second side wall (25) which extends between the end walls, and wherein the second resonator chamber is formed between the second side wall and the end walls of the second resonator tube. The first resonator tube and the second resonator tube are connected to one another in a sound-transmitting fashion via a first connecting orifice (17) between the first side wall and the second side wall.
