ムリング内空間にポンプ室を区画形成し、これら
ポンプ室内に吸入ポートより流体を吸入して後、
吐出ポートへ圧縮吐出するベーンポンプにおいて
、上記吐出ポートよりポンプハウジングに設けた
流体吐出口へ向かう吐出流路の流路壁の一部を、
流体が自由に流通する多数の小孔を有する多孔板
により構成して、該多孔板とポンプハウジング内
壁との間に空間を形成し、該空間を弾性膜体によ
り多孔板側とポンプハウジング側に区画するとと
もに、上記ポンプハウジング側空間内に圧力気体
を封入したことを特徴とするベーンポンプ。 A plurality of vanes are provided on the outer periphery of the rotating rotor to define pump chambers in the cam ring inner space, and after sucking fluid into these pump chambers from the suction port,
In a vane pump that compresses and discharges fluid to a discharge port, a part of the flow path wall of the discharge flow path that goes from the discharge port to the fluid discharge port provided in the pump housing,
It is composed of a perforated plate having a large number of small holes through which fluid freely flows, and a space is formed between the perforated plate and the inner wall of the pump housing, and the space is separated by an elastic membrane between the perforated plate side and the pump housing side. A vane pump characterized in that the pump housing side space is partitioned and a pressure gas is sealed in the pump housing side space.
