DISPOSITIVO PARA AMORTIGUAR EL SONIDO GENERADO POR EL AIRE DE EVACUACION, EL QUE ES UN COMPONENTE INTEGRAL Y TIENE UNA PERFORACION PASADA EN UNA ALMA CON FORMA DE PLATO CONFIGURADO EN UNA SOLA PIEZA.

摘要

The invention relates to a device for damping noise generated by exhaust air, comprising a hollow base body (11) having an inlet opening (13) for the exhaust air and an outlet opening (14) for the exhaust air and a damping means (12), wherein the base body (11) is of modular design and is formed from at least three elements, specifically an inlet piece (15) which forms the inlet opening (13), a damping body (16) as a damping means (12), and an outlet piece (17) which forms the outlet opening (14), and each damping body (16) has a passage bore (27) in the flow direction T of the exhaust air, which device is characterized in that the damping means (12) is an integral part of the base body (11) and the passage bore (27) is formed in a plate-shaped web (30) which is formed in one piece with a cylindrically shaped casing element (31), wherein the web (30) runs in the shape of a funnel both at the input side and also at the output side, in such a way that the exhaust air is compressed in the direction of the passage bore (27) and is expanded again directly downstream of the passage bore (27).
