Ljuddämparanordning och motorfordon innefattande en sådan ljuddämparanordning: Silencer device for piston compressor of motor vehicle has resonator with an inlet aperture set in a wall of a throughflow duct, and has a cross-sectional area larger than or equal to that of the throughflow duct
2011 (English)Patent (Other (popular science, discussion, etc.))Text
The invention relates to a silencer device (10) for connection to a piston compressor of a motor vehicle, which device comprises - a housing (11) with an inlet (12) intended for connection to a suction line or to an air outlet of a piston compressor, and an outlet (13) intended for connection to an air inlet of a piston compressor or to a compressed air line, - a throughflow duct (20) extending through the housing from the inlet to the outlet to allow air to flow from the inlet to the outlet via this throughflow duct (20), and - a quarter-wave resonator (30) situated in the housing and comprising an elongate resonator duct (31) which is curved in its longitudinal direction, has at its one end an inlet aperture (32) situated in a wall of the throughflow duct, and has a cross- sectional area larger than or equal to that of the throughflow duct, the other end (33); of the resonator duct being closed. The invention relates also to a motor vehicle provided with such a silencer device.
