Embodiment Construction
[0029] The technical solution of the present invention is described in detail below through the examples, and the following examples are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being interpreted as a limitation to the technical solution of the present invention.
[0030] The present application provides a variable displacement rotor oil pump, which is different from conventional variable displacement rotor oil pumps in that it does not require the outer rotor to rotate around the center of the inner rotor with a fixed eccentricity, but is realized by adding a pressure regulating plate structure.
[0031] like figure 1 As shown, the variable displacement oil pump of the present application includes a housing 1 , an inner rotor 2 , an outer rotor 3 , a spring 4 , a spring base 5 , a slider 6 , a pressure regulating plate 7 , a cover plate 8 and fixing bolts 9 .
[0032] like figure 2 As shown, t...

The invention relates to a variable-displacement rotor oil pump. The pump comprises a shell, an inner rotor, an outer rotor, a spring, a spring base, a sliding block, a pressure adjusting plate and a cover plate; the inner rotor is installed in the outer rotor and installed in the shell, one end of the spring is connected with the sliding block, the other end of the spring is installed in the shell after being connected with the spring base, the sliding block is connected with the pressure adjusting plate, the pressure adjusting plate is installed in the position, between the outer rotor and the cover plate, of the shell, the pressure adjusting plate rotates in a limited mode relative to an inner cavity of the shell, and the cover plate is installed on the shell through fixing bolts. According to the technical scheme, the performance of the oil pump is adjusted, the sliding environment of moving parts of an engine is improved, and oil is supplied according to needs; power waste of the engine at the high rotating speed is reduced through the pressure adjusting plate structure, and the oil saving effect is achieved; besides, the structure is simple, in the implementation process, the rotor does not move relatively, the reliability is good, parts are few, and the cost can be reduced.
Description
technical field [0001] The invention belongs to the technical field of engine oil pumps, and specifically refers to a variable displacement rotor oil pump. Background technique [0002] As an essential part of the engine, the oil pump is used to push the oil to a certain pressure and force it to be sent to the moving surfaces of the various parts of the engine. Common structural types of oil pumps include gear pumps, vane pumps, and rotor pumps. The performance of the oil pump is designed according to the actual needs of each engine. If the performance of the oil pump is too low, it will lead to poor lubrication of the moving parts of the engine and cause the failure of the whole machine. If the performance of the oil pump is too high, it will increase the power loss and waste of the engine, and The requirements for the sealing parts of the engine are relatively high, and the problem of oil leakage is prone to occur. [0003] The commonly used variable displacement oil pum...
