Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as figure 1 As shown, the oil pump displacement regulating device of the present invention includes an eccentric ring 2 arranged in the pump cavity 1, a rotor 3 eccentrically arranged with the special-shaped inner cavity of the eccentric ring 2, and a rotor 3 for reducing the eccentric ring 2 Emission reduction adjustment mechanism 4 with the eccentric distance of the rotor 3. The above-mentioned eccentric ring 2 refers to an annular stator with an inner cavity in the middle, and its inner cavity is a special-shaped inner cavity formed by several arc surfaces. The rotor 3 is arranged in the special-shaped inner cavity, and the rotor The axis position of 3 is set eccentrically in the special-shaped inner chamber. The so-called eccentricity means that the axis position of the rotor 3 is not collinear at the geometric center of the sp...

Abstract

The invention discloses an oil pump displacement regulating device, which comprises an eccentric ring (2) arranged in the pump cavity (1), and a rotor (3) arranged eccentrically with the special-shaped inner chamber of the eccentric ring (2). and an emission reduction adjustment mechanism (4) for reducing the eccentric distance between the eccentric ring (2) and the rotor (3), characterized in that: the oil pump displacement adjustment device also includes an increase emission adjustment mechanism (5), The displacement increase adjustment mechanism (5) is respectively connected with the oil discharge port (7) and the main oil circuit (8) through the solenoid valve (6), and the solenoid valve (6) is electrically connected with the control unit (9). By adopting the structure of the invention, the multi-stage adjustable displacement of the oil pump can be realized, the utilization rate of the hydraulic energy of the oil is improved, and energy waste is reduced.

Description

technical field [0001] The invention relates to an oil pump, in particular to an oil pump displacement regulating device. Background technique [0002] When the automobile engine is working, due to the friction between the parts, it must be equipped with a lubrication system. And the lubrication system of existing automobile engine is generally made up of oil pump and related conveying and control equipment, provides high-pressure oil liquid through oil pump, conveys to the surface of each component, plays a lubricating role. The flow rate of the high-pressure oil provided by the oil pump is completely determined by the fixed speed and displacement. This type of traditional quantitative oil pump is called a fixed displacement oil pump. It can be seen that for a fixed displacement oil pump, when the speed of the oil pump is high, the output flow of the oil is relatively large, and the lubricating oil required by the engine does not need so much, which causes More high-press...
