Claims (1)

  1. 로터의 외주에 복수 설치한 베인에 의해 캠링의 내주공간을 구획해서 펌프실로 하고, 상기 로터의 회전에 따라 용적이 확대되는 펌프실내에 복수의 흡입포트에서 유체를 흡입하는 동시에, 상기 로터의 회전에 따라 용적이 축소되는 펌프실에서 복수의 토출포트로부터 유체가 압축토출되어, 펌프하우징내에 형성된 압력실을 거쳐서 토출유체를 유출하는 베인펌프에 있어서, 상기 압력실을 적벽에 의해 복수로 분할하고, 그 분할한 각 압력실에 상기 복수의 토출포트를 각각 개구시키고, 상기 압력실의 하나에 토출유체의 유출구룰 개구시키고, 또한 상기 격벽에 스로틀구멍을 형성한 것을 특징으로 하는 베인펌프.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
