Abstract

[목적][purpose]

본 발명의 목적은 흡인코넥터를 몸체에 부착하기 쉽고 또한 그들을 고정하는 볼트의 갯수도 최소한이면 되는 유압펌프를 제공하는 것이다.An object of the present invention is to provide a hydraulic pump in which the suction connector is easy to attach to the body and the number of bolts for fixing the suction connector is at least the minimum.

[구성][Configuration]

흡입구(11)와 흡인코텍터(c)의 삽입돌출부(16) 각각에 서로 방향으로 반대로 한 환상단부(12) 및 (15,16)을 형성하여 상기 삽입돌출부를 흡입구에 삽입했을 때 이들 환상단부가 어울려서 환상의 시일홈(18)을 구성하도록 하고 있다. 그리고 이 시일홈(18)의 측면이며 축선에 직교하는 방향으로 서로 대향하는 면을 끼워맞춤공차의 작용면(18a,18b)으로 함과 동시에 이들 끼워맞춤공차의 작용면을 서로 평행하게 한다. 그리고 시일홈에 조립한 시일(19)의 끼워맞춤공차에 의한 탄성력이 끼워맞춤공차의 작용면에만 작용하는 구성으로 하고 있다. 또한 흡인코넥터(c)의 삽입돌출부의 외경을 몸체의 흡입구 내경보다도 약간 크게 하여 삽입돌출부를 흡입구에 강제적으로 밀어넣음으로써 흡인코넥터가 흡입구에 임시 고정되는 구성으로 하고 있다.When the insertion protrusions are inserted into the suction port by forming the annular end portions 12 and 15 and 16 opposite to each other in the insertion protrusions 16 of the suction port 11 and the suction port c, So that the annular seal groove 18 is formed. The side surfaces of the seal groove 18 and the surfaces opposed to each other in the direction perpendicular to the axial line are used as the action surfaces 18a and 18b of the fitting tolerances and the working surfaces of the fitting tolerances are made parallel to each other. And the elastic force due to the fitting tolerance of the seal 19 assembled into the seal groove acts only on the action surface of the fitting tolerance. And the insertion protrusion of the suction connector c is slightly larger than the inner diameter of the suction port of the body so that the suction connector is temporarily fixed to the suction port by forcibly pushing the insertion protrusion into the suction port.
