Hand control valve is used to operate longitudinal spring energy storage control chamber, so that parking system safety can be fully relied on. Due to the special characteristics of the junction structure, the braking action can be sensitive with spirit and follow up.
1 row of parking space:
In the driving state, the compressed air passes through the (intake) air port 1 and the open intake valve (1), to the (outlet) air port 21, and the spring energy storage control chamber is charged.
2 System moving position:
When braking, the convex wheel (2) will push the rod (3) down, the intake valve (1) closed, the exhaust valve (6) open, the outlet 21 through the exhaust port 3 exhaust.
When the leveling plug (5) moves down in the spring (4), the exhaust valve (6) is closed and the intake valve has not been opened, the leveling is reached, and a system overrun process is realized
