Abstract
The invention is disclosed to variably control the amount of compressed air flowing per unit hour depending on the change in the level position of the wheel axles in a moving vehicle when the compressed air flows into air springs from the leveling valve or when the compressed air flows out of the air springs through the leveling valve, so as to make it possible to variably control the time to restore the status of the vehicle body depending on the level of rollings caused when the vehicle turns a corner, thereby achieving turning stability, higher response speed and steering.
Claims6
A variable leveling valve apparatus for a vehicle, comprising:
- a housing defining an inlet and an outlet connected by a flow path through which compressed air flows into and out of said housing;
- a connecting path defined by said housing and branched from the flow path and configured for connecting left and right air springs;
- a flow amount control means installed at the flow path for respectively controlling the amount of compressed air per unit hour flowing into the flow path through the inlet and the amount of compressed air per unit hour flowing outside through the connecting path to the outlet;
- a plunger linearly moveable to operate the flow amount control means wherein said plunger is linearly moveable and housed in the flow path;
- a rotor configured to linearly move said plunger;
- and
- a lever with one end coupled to said rotor for rotatably moving said rotor in responose to a change in distance between a vehicle axle and a vehicle body.
A variable leveling valve apparatus for a vehicle, comprising:
- a first fixing plate defining first through holes therethrough configured for passage of inlet air;
- a plurality of valves configured with a head portion and a leg protion;
- a second fixing plate defining holes therethrough configured for receiving said leg portions of said valves wherein said holes are larger in diameter than said leg portions of said valves and wherein said head portions of said valves seat within said holes thereby closing said holes;
- springs disposed between said first fixing plate and said head portions of said valves for supporting said valves in a closed position;
- a plunger configured for linear displacement;
- an operating plate disposed between said plunger and said leg portions of said valves wherein said operating plate is configured for linear displacement in response to linear displacement of said plunger;
- a rotor configured to linearly displace said plunger;
- and
- a lever configured for actuation said rotor in response to movement between an axle and a vehicle.
