More particularly, the present invention relates to a solenoid valve regeneration method for regenerating a solenoid valve, The present invention relates to a solenoid valve regeneration tool and a solenoid valve regeneration method using the solenoid valve regeneration tool.

The vehicle's automatic transmission consists of a torque converter that transmits power, a valve body that controls the hydraulic pressure, each brake and clutch, and a planetary gear and differential that controls the speed.

Here, the valve body is equipped with various solenoid valves such as an overdrive solenoid valve, an underdrive solenoid valve, a second solenoid valve, and a damper solenoid valve, and is used to control the oil in each gear of the transmission.

The solenoid valve used in the vehicle can be divided into an on / off type solenoid valve and a variable pressure solenoid valve according to its operation method. The variable pressure type solenoid valve can be used in automobiles such as an injector, an exhaust control system, a power steering, Automatic transmission, and the like.

Particularly, a solenoid valve for a vehicle is generally used for ultra-high speed (response time is 30ms or less), and is optimized for each use.

In addition, the on / off solenoid valve applies a constant current to the coil of the solenoid valve so that the plunger is operated and the valve is opened or the valve closing operation is repeatedly performed to adjust the flow of the fluid. It is used in many fields as possible.

 The solenoid valve for pressure control is classified into a spool type, a ball type, a poppet type, and the like depending on its internal structure. An example of a spool type solenoid valve is disclosed in "Solenoid Valve" of Patent Publication No. 10-2014-0066559 .

 The solenoid valve is largely composed of a solenoid which operates when the power is applied and a valve which controls the flow of the fluid by the operation of the solenoid.

Accordingly, when power is applied to the coil, the plunger reciprocates within the yoke and moves the spool to connect or disconnect the plurality of ports.

The operation of these solenoid valves is not problematic at first, but when the period of use is increased, malfunctions are caused due to accumulation of foreign substances and bushing wear.

Particularly, when the foreign matter is accumulated in the solenoid valve, the response of the plunger which reciprocates linearly at a very high speed in the inside of the yoke is slowed, and the direction of wear motion of the bushing is changed to cause a malfunction in the solenoid valve. Causing serious defects.

However, since there is no specific solenoid valve disassembling and cleaning tool to solve the above-described problem, the transmission itself needs to be replaced, and the dismounted transmission is discarded without being reused, which leads to waste of resources, There is a problem that leads to the problem of.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a solenoid valve regeneration tool capable of disassembling and assembling a solenoid valve for removing foreign matters accumulated therein and a solenoid valve regeneration method using the solenoid valve regeneration tool.

It is another object of the present invention to provide a solenoid valve regeneration tool capable of regenerating a solenoid valve through replacement of parts constituting foreign matter and constitution, and a solenoid valve regeneration method using the same.

It is another object of the present invention to provide a solenoid valve regeneration tool in which the performance of a regenerated solenoid valve is maximized and malfunction of the solenoid valve is reduced, and a solenoid valve regeneration method using the same.

Another object of the present invention is to provide a solenoid valve regeneration tool and a solenoid valve regeneration method using the solenoid valve regeneration tool, in which the performance and life span of an apparatus in which a solenoid valve is installed is regenerated through regeneration of the solenoid valve.

It is another object of the present invention to provide a solenoid valve regeneration tool in which replacement of an assembly device in which a solenoid valve is installed is reduced, waste of resources, cost loss, and environmental pollution are prevented, and a solenoid valve regeneration method using the same.
