Embodiment Construction

[0045] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the application. However, the present application can be implemented in many other ways different from those described here, and those skilled in the art can make similar promotions without violating the connotation of the present application. Therefore, the present application is not limited by the specific implementation disclosed below.

[0046] Figure 1 to Figure 2 An embodiment of a rotor type variable displacement pump provided by the present application is shown. The rotor type variable pump of this embodiment is used in the automobile engine as the power part of the automobile lubrication system, so it is also called variable displacement oil pump in this embodiment, referred to as the variable pump, and the working medium therein is engine oil. Of course, the rotor type variable displacement pump provided in this application can also be applie...

Abstract

The invention provides a rotor variable pump. The rotor variable pump comprises a pump body, a pump cover, an inner rotor, an outer rotor, an adjusting ring and a force application device; the adjusting ring is provided with pitch circle arc segments; matching arc segments corresponding to the pitch circle arc segments are arranged on the pump body; when the pressure in the pump body is increased, the adjusting ring rolls on the matching arc segments under the limit of the engagement relation between adjusting teeth segments and fixed teeth segments and the limit of the pitch circle arc segments and the matching arc segments of the pump body, and the adjusting ring is made to move towards an oil inlet area; when the pressure in the pump body is deceased, under the action force of the force application device, the adjusting ring rolls on the matching arc segments of the pump body under the limit of the engagement relation between the adjusting teeth segments and the fixed teeth segments and the limit of the pitch circle arc segments and the matching arc segments of the pump body, the adjusting ring is made to move towards an oil outlet area, and therefore the moving track of the adjusting ring is limited; accordingly, under the condition of certain eccentric distance of the inner and outer rotors, the eccentric position of rotation by the outer rotor around the center of the inner rotor can be changed, and the purpose of adjusting displacement of a fuel pump is achieved.

Description

technical field [0001] The application relates to a hydraulic pump, in particular to a rotor type variable displacement pump. Background technique [0002] At present, the oil pump matched with the automobile engine has transitioned from the traditional quantitative pump to the variable pump. The displacement of the traditional fixed-displacement oil pump is set according to the low-speed and high-pressure working conditions of the engine. The oil supply increases linearly with the increase of the engine speed. After medium and high speeds, it is far higher than the actual lubrication demand of the engine, resulting in waste of energy consumption. The variable displacement pump can automatically adjust the displacement of the pump according to the pressure at the outlet end, realizes the oil supply according to the lubrication requirements of the whole machine, avoids the waste of energy consumption caused by excessive oil supply, achieves the purpose of energy saving, and r...
