The utility model also relates to diesel engine, and it is equipped with oil pump, and this oil pump comprises the pump housing and the pump cover that covers with this pump housing; Offer on this pump cover oil inlet hole and and this oil inlet hole between form the oil outlet of oil circuit; Wherein, this oil pump also comprises the transmitting assemblies that is housed in this pump housing, and this transmitting assemblies comprises driving shaft, sheathedly is fixed on the internal rotor on this driving shaft and is set in the external rotor on this internal rotor; This internal rotor thickness is even; This external rotor variable thickness, this oil inlet hole and this oil outlet are positioned at the relative both sides of this driving shaft, are the oil circuit of this oil inlet hole towards this oil outlet between this internal rotor and this external rotor.
As the further improvement of such scheme, also contain the half dollar key in this driving shaft, this half dollar key, this internal rotor, this external rotor are positioned on the same aspect.
As the further improvement of such scheme, an end of this driving shaft is housed in and is provided with this internal rotor and this external rotor in this pump housing, and the other end of this driving shaft extends in the outer and sheathed driving gear that is fixed with of this pump housing.
As the further improvement of such scheme, this diesel engine also comprises the idle gear of the driving shaft that external impetus to this oil pump is provided, this idle gear and the engagement of this driving gear.
Oil pump that the utility model provides and the diesel engine with this oil pump have the following advantages: through adopting the transmitting assemblies of inner and outer rotors; Therefore this oil pump is accommodated the volume increase of oil; Flow increase, pressure increase during work; Can better guarantee the sufficient lubrication of diesel engine each parts when proper functioning, reduce the wearing and tearing at each position of diesel engine, prolong the working life of diesel engine.
