Abstract

uma estrutura de bomba de óleo para um motor de combustão interna é fornecida em que um invólucro de bomba para uma bomba trocoide que compreende um eixo de bomba, um rotor interno que gira com o eixo de bomba e um rotor externo que engata com o rotor interno é formado a partir de um cárter e uma cobertura de bomba, uma parte de rebaixo que acomoda o rotor interno e o rotor externo sendo fornecida no cárter, e a cobertura de bomba sendo montada no cárter de modo a cobrir a parte de rebaixo, em que uma primeira parte de mancal (58) que sustenta de modo giratório uma parte de extremidade do eixo de bomba (52) é fornecida ao cárter (11), e uma segunda parte de mancal (60) que sustenta de modo giratório a outra parte de extremidade do eixo de bomba (52) é fornecida em um membro de suporte fixo (28) disposto no lado externo do invólucro da bomba (50). isto permite que a cobertura de bomba tenha uma espessura pequena, dessa forma permitindo que o peso e o custo sejam reduzidos.An oil pump frame for an internal combustion engine is provided wherein a pump housing for a trocoid pump comprising a pump shaft, an inner rotor rotating with the pump shaft and an outer rotor engaging with the rotor. The inner shell is formed from a crankcase and a pump cover, a recess portion accommodating the inner rotor and the outer rotor being provided in the crankcase, and the pump cover being mounted in the crankcase to cover the recess portion, wherein a first bearing part (58) pivotally supporting one end portion of the pump shaft (52) is provided to the crankcase (11), and a second bearing part (60) pivotally supporting another pump shaft end portion (52) is provided on a fixed support member (28) disposed on the outside of the pump housing (50). This allows the pump cover to be small in thickness, thereby allowing weight and cost to be reduced.
