Problems solved by technology

Conventional oil control valves often suffer from backflow, resulting in insufficient responsiveness
At the same time, the design of the oil inlet port of the traditional oil control valve makes the processing of the oil channel on the reversing rod complicated and requires high control accuracy.

Abstract

The invention relates to an engine oil control valve provided with a valve sleeve and a reversing rod. The valve sleeve is provided with a plurality of oil opening groups. A lining assembly and a check valve assembly are arranged in the valve sleeve fixedly. The reversing rod is provided with an annular groove, and the annular groove and the lining assembly form an oil cavity. The lining assembly is provided with a plurality of oil hole groups and a plurality of oil inlets. The reversing rod is slidably arranged in the lining assembly. The right end of the valve sleeve is provided with a first oil inflow opening. The check valve assembly comprises a valve seat, a ball valve and a check valve spring. The valve seat is arranged between the lining assembly and the first oil inflow opening and is provided with a second oil inflow opening communicating with the first oil inflow opening, and oil outlets communicating with the oil inlets in the lining assembly. The ball valve is slidably arranged in the valve seat. The check valve spring is arranged between the right end of the lining assembly and the ball valve. The ball valve is matched with the second oil inflow opening correspondingly under the action of the check valve spring. Through the engine oil control valve, backflow can be prevented effectively, responsiveness is improved, and response time is shortened.

Description

technical field [0001] The invention relates to automobile timing system components, in particular to an engine oil control valve. Background technique [0002] The variable valve timing technology (VVT) of the engine is to adjust the intake air volume by controlling the opening angle of the intake valve to advance and lag, so as to achieve the ultimate goal of reducing intake air at low speeds, reducing fuel consumption, and increasing intake air at high speeds to increase power. . The VVT ​​system is mainly composed of a VVT assembly and an oil control valve (OCV). Among them, the phase adjustment of the VVT ​​assembly requires an oil control valve to control the input and output of the oil. Therefore, the oil control valve plays a very important role in the entire VVT ​​system. [0003] The oil control valve mainly includes valve body (including electromagnetic coil, control module connector, etc.), reversing rod, return spring and other components. Its principle is m...
