なわれる。Next, the operation of this conventional hydraulic control valve for a guided wheel will be explained. Valve 1 is pressed by spring 6 on valve seat 5 to increase the oil pressure at trap point A. Next, by energizing the coil 3, a magnetic field is generated in the core 2, the valve 1 is pulled up, and oil flows out from the oil outflow opening 5a formed in the valve seat s. As a result, the oil pressure in the 50-yen chamber of the valve seat decreases. Next, when the 'a electric current is completely cut off, the magnetic field disappears and the valve 1 is pressed against the valve seat 5 by the reaction force of the spring 6, so that the oil pressure at point A becomes high again. By changing the ratio of energized and de-energized time, the oil pressure (MAX) during de-energized
Hydraulic pressure is controlled from (pressure) to (hydraulic pressure CMIN pressure when energized).

ルブスティックが起きるなどの問題点があった。In this process, the conventional hydraulic control valve for motor vehicles is non-'1JJ.
During one electrification, high pressure was built up at point A, while point B was at atmospheric pressure, so a differential pressure was created between points A and B, causing oil to penetrate into the gap between valve 1 and guide 4 due to the capillary phenomenon. Also,
At the same time, fine dust in the oil also entered the engine, causing problems such as valve sticking.

ブスティックが低減される。According to the automobile hydraulic control valve of the present invention, a hole is made in the guide that supports the valve, and the gap between the valve and the guide is communicated with the same chamber of the valve seat.
The pressure at the point and the zero point are the same, and there is no differential pressure, which reduces the amount of oil and dust that enters the gap between the valve and the guide, reducing valve stick.
