Problems solved by technology

[0003] In the prior art, the valve body of the OCV valve is usually provided with a three-way annular groove, and a radial through hole communicating with the inner cavity of the valve body is arranged in the groove, and a filter screen is covered in the groove, and the filter screen is usually made of a metal strip. Connected end to end and welded into a complete annular filter screen, therefore, when the OCV valve needs to be cleaned, it can only destroy the filter screen to make the radial through holes in the groove unobstructed, and then clean it; the existing defects are: 1 1. The filter screen is a consumable accessory; 2. The operation of cleaning the OCV valve is cumbersome
[0006] Among them, when the spool moves in the coil, the chambers on the upper and lower sides of the spool circulate air through the gap between the spool and the coil.
Moreover, the ejector rod is fixed in the through hole in the middle of the valve core. After a period of use, the ejector rod has a potential safety hazard of loosening (that is, the ejector rod is embedded deeper in the valve core), resulting in failure of the oil circuit switching mechanism.

Embodiment 1

[0034] Embodiment 1: An OCV valve with an improved structure, including a housing 1, a valve body 4 installed at the lower end of the housing 1, a solenoid valve assembly disposed in the housing and a reversing rod 14 disposed in the valve body 4, the valve The body is hollow cylindrical, and the peripheral wall of the valve body 4 is provided with several annular grooves 19 (three grooves 19 in this embodiment) from top to bottom. The radial through hole 3 (the shape of the radial through hole 3 can be set according to needs, in the present embodiment, the radial through hole arranged in the ring groove in the middle of the three grooves is an oil return hole, so it can be designed Relatively large size), all or part of the groove 19 is detachably covered with a filter screen 5 (in this embodiment, the radial through holes located on the upper and lower sides of the groove are all communicated with the phaser The oil outlet hole, so it is necessary to set the filter screen; t...

Embodiment 2

[0042] Embodiment 2: This embodiment is basically the same as Embodiment 1, the difference is that the ejector rod 33 and the reversing rod 34 are an integral structure, and the front end of the ejector rod 33 is against the center of the valve core 31; the skeleton The lower end of the base is connected with a base, and the side of the base facing the valve core is provided with a magnetic isolation sheet 32; The magnetic isolation sheet 32 ​​. The design of the magnetic isolation sheet 32 ​​makes the solenoid valve assembly more efficient and more practical. This embodiment not only solves the matching problem caused by looseness between the ejector rod and the valve core, but also saves assembly steps and reduces costs. In addition, in this embodiment, exhaust grooves can be provided on the peripheral side of the valve core as required to ensure smooth flow of air between the chambers on the upper and lower sides of the valve core. In this embodiment, the three annular gr...

Abstract

The invention belongs to the technical field of an OCV (Oil Control Valve) and particularly relates to an OCV valve with an improved structure. The OCV valve comprises a casing, a valve body arranged at the lower end of the casing, an electromagnetic valve assembly arranged in the casing as well as a reversing lever arranged in the valve body, wherein the valve body is of a hollow cylinder shape; a plurality of annular grooves are formed in the circumferential wall of the valve body from top to bottom; a radial through hole communicated to an inner cavity of the valve body is formed in each groove; filtering screens cover the insides of all or part of grooves in a detaching way; a spring winds the outer side of each filtering screen; each filtering screen is bound in the corresponding groove by the corresponding spring; each filtering screen shields the radial through hole in the corresponding groove. The filtering screens disclosed by the invention can be reused; when the OCV is cleaned, the springs are required to be separated from the surfaces of the filtering screens, and then the filtering screens can easily fall off from the insides of the grooves and can be recycled, so that the condition that the filtering screens are disposable consumables is avoided; in addition, the separation operation of the filtering screens is simple, convenient, safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of OCV valves, in particular to an OCV valve with an improved structure. Background technique [0002] When the engine is under different working conditions, the ECU of the car will control the action of the OCV valve, and the reversing rod inside the OCV valve will move forward and backward to change the oil passage. If the oil passage is different, a certain amount of oil will be introduced into the cam phase adjuster. There are blades between the rotor and the stator of the phase adjuster, which divides a chamber into two spaces. When the oil enters from one side, the timing will be advanced, and when the oil enters from the other side, the timing will be delayed. At the same time, the amount of engine oil entering the cam phase adjuster determines the variation of the valve timing. The engine system controls the change of the oil passage of the OCV valve to realize the advance or lag of the cam phase adj...
