Silencer and water supply device

Abstract

A muffling apparatus capable of attaining the prevention of the occurrence of a noise reliably while making concrete the reduction of the manufacturing cost and the easiness of the assembling of the same apparatus, and a feed water apparatus having such a muffling effect are provided. The muffling apparatusis an apparatus connected to a jet pipeadapted to send out the water, which flows in a feed water passagein the interior thereof, into storage water W. The apparatus has a tubular portionconnected to an upstream side portion of the jet pipeso that the tubular portionextend downward, and having therein a water supply passagecommunicating with the feed water passage, and a housingconnected water-tightly to an upstream side portion of the jet pipeand an upper section of the tubular portion, enclosing a lower section of the tubular portion, connected water-tightly to a downstream side portion of the jet pipe, and capable of storing the air, which is in the interior of the jet pipe, in the portion of the interior of the housingwhich is outside the tubular portion. The tubular portionis provided at an upper section thereof with an air holemade through a wall thereof so as to communicate the water supply passagewith the interior of the housing
