Abstract

본 발명에 의하면, 밸브체(18)에 있어서의 제1시이트부(S1)와 제2시이트부(S2)와는 축방향으로 떨어져 있고, 그들 사이로 통형상부분(18a)을 구비하고 있다. 통형상부분(18a)에는 지지부재(42)를 끼워 붙이고 있고, 그 지지부재(42)의 내주면으로 원통형상인 금속필터로 된 소음부재(41)를 설치하고 있다.
배력장치의 작동시에는, 압력통로(23)내의 압력유체는 떨어진 양쪽 제2시이트부(S2)의 사이를 통과한 후, 소음부재(41)의 배부를 유통한 다음 변압실(B), (D)로 유입한다.
이때, 양쪽 제2시이트부(S2)의 사이를 통과한 압력유체는 상기한 소음부재(41)의 내부를 유통하으로서, 흐름의 방향을 갖추어지게 되고 소용돌이형상인 난류로 되는 것이 방지된다.
따라서, 배력장치의 작동시 응답성을 저하시키지 않고 흡기음을 저강할 수 있다.
