Problems solved by technology

[0005] First, the two oil pumps are difficult to arrange in the limited space of the engine, and the cost is relatively high; moreover, with the development trend of miniaturization, this arrangement cannot meet the demand;
[0006] Second, it is difficult for the two oil pumps to ensure that the lubrication is carried out simultaneously and synchronously, resulting in inconsistent working conditions of the two rows of cylinders, which affects the performance of the engine

Embodiment Construction

[0028] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Please refer to figure 1 , figure 1 It is a three-dimensional structural schematic diagram of a specific embodiment of the oil pump provided by the present invention.

[0030] The oil pump in this embodiment is used for lubricating a dual-row engine, which has two rows of cylinders. The oil pump includes an oil inlet 113, a first oil outlet 111a and a second oil outlet 112a, that is, the oil pump has a structure of "one inlet and two outlets". Engine oil enters the pump body 11 of the oil pump from the oil inlet 113, and the pumped oil flows out through the first oil outlet 111a and the second oil outlet 112a. The two oil outlets of the oil pump are distributed on both sides of the oil pump, so as to correspond ...

Abstract

The invention discloses an oil pump used for lubricating a double-row type engine. The oil pump comprises an oil inlet, a first oil outlet and a second oil outlet. The first oil outlet and the second oil outlet are distributed in the two sides of the oil pump and correspondingly lubricate two rows of air cylinders of the double-row type engine respectively. According to the designed oil pump, pumped machine oil can flow out of the two oil outlets, so that the two rows of air cylinders of the double-row engine are respectively lubricated. Therefore, the double-row engine can be lubricated with only one oil pump. Compared with the background technology, the oil pump has the advantages that the one oil pump is easy to arranged in the limited space of the engine, cost can also be reduced, and the development requirement for miniaturizing the engine is met; the two oil outlets of the one oil pump can synchronously pump the machine oil, so that the two rows of air cylinder are uniform in working condition, and performance of the engine is fully brought into play.

Description

technical field [0001] The invention relates to the technical field of pump bodies, in particular to an oil pump. Background technique [0002] The oil pump can provide pressure oil with a certain pressure to forcibly supply oil to the friction surfaces of various parts of the engine, so as to achieve the effect of lubrication. [0003] The existing oil pump structure is a one-in-one-out structure, that is, the oil pump is only provided with one inlet and one outlet, which can meet the general engine lubrication requirements. And for double-row engine, because it has two rows of cylinders, the oil pump of one inlet and one outlet structure can only lubricate one row of cylinders, so the double-row engine needs two oil pumps to lubricate the two rows of cylinders respectively. [0004] There is following technical problem in this structure: [0005] First, the two oil pumps are difficult to arrange in the limited space of the engine, and the cost is relatively high; moreove...
