Abstract

본 발명은 베인 펌프에 관한 것으로,더욱 상세하게는 비평형형 로터리베인 펌프에 있어서,로타축의 회전운동을 원활히 하고 펌프 하우징 및 커버의 과도한 마모 및 이상 소음을 저감시키도록 한 것이다.또한 본 발명에서는 펌프의 조립 공차값을 크게 하기 위하여,펌프부하의 변화에 따라서 압력판이 축방향으로 움직일 수 있도록 하여 로타축의 작동을 원활히 하고,로타축과 펌프 하우징 및 커버에서 발생하는 과도한 마모 방지 및 이상 소음을 저감시켜 펌프의 내구성 및 성능을 향상시킴은 물론,펌프의 가공성을 향상시킬 수 있는 로터리 베인 펌프를 제공함에 있는 것이다.The present invention relates to a vane pump, and more particularly, to a non-equilibrium rotary vane pump, which facilitates rotational rotation of the rotatable shaft and reduces excessive wear and abnormal noise of the pump housing and cover. In order to increase the assembly tolerance of the pump, the pressure plate can move in the axial direction according to the change of the pump load to facilitate the operation of the rotatable shaft, and to prevent excessive wear and abnormal noise generated from the rotatable shaft, the pump housing and the cover. In addition to improving the durability and performance of the pump, and to provide a rotary vane pump that can improve the processability of the pump.
