Abstract
(EN) A silencer, comprising a housing. The housing encloses a hollow cavity. The cavity comprises a cylindrical chamber (510) and a cuboidal chamber (520). One of the bottom surfaces of the cylindrical chamber (510) is connected to a first surface (521) of the cuboidal chamber (520). The cylindrical chamber (510) is in communication with the interior of the cuboidal chamber (520), and the cylindrical chamber is provided with an air inlet (540) and an air outlet (550).
(FR) La présente invention concerne un silencieux comprenant un logement. Le logement renferme une cavité creuse. La cavité comprend une chambre cylindrique (510) et une chambre cuboïde (520). Une des surfaces inférieures de la chambre cylindrique (510) est raccordée à une première surface (521) de la chambre cuboïde (520). La chambre cylindrique (510) est en communication avec l'intérieur de la chambre cuboïde (520), et la chambre cylindrique est pourvue d'une entrée d'air (540) et d'une sortie d'air (550).
(ZH) 一种消音器,包括壳体,壳体围合形成一中空的腔体,腔体包括一圆柱形腔室(510)及一长方体腔室(520),其中圆柱体腔室(510)的底面之一与长方体腔室(520)的第一表面(521)连接,圆柱体腔室(510)与长方体腔室(520)的内部相导通,圆柱体腔室设置进气口(540)和出气口(550)。
