OCV valve for VVT engine

Abstract

The invention discloses an OCV valve for a VVT engine. The OCV valve for the VVT engine comprises a valve body and a plurality of oil leakage ports formed in the surface of the valve body. A filter mesh piece is wound on the position, corresponding to the oil leakage ports, of the surface of the valve body. A ring of fixing pieces are fixedly connected to the outer side of the filter mesh piece. Aplurality of positioning rods are uniformly and fixedly connected to the position, corresponding to the oil leakage ports, of the surface of the valve body and are symmetrical with respect to the oilleakage ports. Positioning holes corresponding to the positioning rods are arranged in the surfaces of the fixing pieces. A plurality of positioning blocks and correspondingly positioning frames areuniformly and fixedly connected to the two ends of the fixing pieces. Cylindrical grooves are separately arranged in the two opposite walls of the positioning bock. A thrust spring is arranged insideeach cylindrical groove. One end of each thrust spring is fixedly connected with the inner wall of the corresponding cylindrical groove, and the other end of each thrust spring is fixedly connected with a limiting rod; and the inner walls of the positioning frames are provided with limiting holes corresponding to the limiting rods. By means of the OCV valve for the VVT engine, the filter mesh piece is convenient to disassemble and assemble, so that the valve is convenient to use.

Description

technical field [0001] The invention relates to the technical field of an OCV valve body, in particular to an OCV valve body for a VVT engine. Background technique [0002] The OCV valve is an important part of the continuously variable valve timing system of the automobile engine. During actual use, the impurities in the oil can easily cause the OCV valve to get stuck, resulting in the abnormal operation of the entire VVT ​​system. [0003] After retrieval, the patent authorized announcement number is CN 204060851 U, which proposes a spring-fixed strainer type engine VVT ​​oil control valve, including a valve body, which is characterized in that: a strainer is installed outside the oil port of the valve body, and The mesh cover has a fixed spring. This patent uses the fixed spring sleeve on the filter mesh to realize the limit fixation of the filter mesh. When disassembling the filter mesh, it is necessary to forcefully expand the fixed spring to use it, which is laborious ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of using a fixed spring sleeve on the filter screen in the prior art to realize the limit fixation of the filter screen. When the filter screen is disassembled and assembled, it is necessary to forcefully expand the fixed spring to use it. It is laborious and inconvenient, and the fixed spring will block the meshes of some filter meshes, which will affect the use of the OCV valve. An OCV valve body for VVT engines is proposed
