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...
