Abstract

흡입 제어부를 갖는 펌프로서 또한 구성되는 본 발명에 따른 속기어 펌프는 압력구역 내에서의 불필요한 공동화효과를 감소시키고 오일이 감소된 변위셀들로부터 기어의 톱니 사이로 유동되도록 허용한다. 또한 임피던스-제어식 오버플로우통로가 제공되며 변위셀들을 향하는 개구부들은 기어의 하나 이상의 톱니에 의해 교대적으로 개.폐되게 된다.The short gear pump according to the invention, which is also configured as a pump having a suction control, reduces the unnecessary cavitation effect in the pressure zone and allows oil to flow from the reduced displacement cells between the teeth of the gear. An impedance-controlled overflow passage is also provided and the openings towards the displacement cells are alternately opened and closed by one or more teeth of the gear.
