초록 ▼

The present invention concerns a control valve for use in a vehicle anit-lock braking systm adapted to control the application of pressurized brake fluid to at least one selected vehicle brake. The valve includes an outer housing having an inlet coupled to receive pressurized brake fluid from the vehicle master cylinder and an outlet coupled to supply pressurized brake fluid to the selected vehicle brakes. A passageway is formed in the housing for connecting the inlet to the outlet. A normally open isolation valve is located in the passageway and is utilized to control the flow of fluid through the passageway between the inlet and the outlet. When an incipient wheel lock condition is detected, the isolation valve can be closed to prevent a further increase in pressure to the controlled brakes and to hold the pressure supplied to the controlled brakes at a relatively constant level. After the isolation valve has been closed and it is desired to further increase the pressure to the controlled brakes, the valve can be momentarily opened to enable increased pressure from the vehicle master cylinder to be supplied to the controlled brakes. In accordance with the present invention, a damping mechanism is associated with the isolation valve for damping the movement of the valve as the valve is moved from the closed position. It has been found that such damping enables the reapplication of pressure to the selected brakes to be more precisely controlled.

A control valve for use in a vehicle anti-lock braking system adapted to control the application of pressurized brake fluid to at least one selected vehicle brake, said valve comprising: an outer housing having an inlet coupled to receive pressurized brake fluid and an outlet coupled to supply pressurized brake fluid to the selected vehicle brake, said housing having a passageway formed therein for connecting said inlet to said outlet; normally open isolation valve means located in said passageway for controlling the flow of fluid through said passageway between said inlet and said outlet, said valve means movable between a normally open position wherein fluid can flow from said inlet to said outlet and a closed position wherein fluid is prevented from flowing from said inlet to said outlet; means for exerting a biasing force to urge said valve means toward said normally open position; solenoid means responsive to a control signal for moving said valve means from said open position to said closed position; said valve means and said housing means cooperating to define a chamber for containing brake fluid, said chamber varying in volume as said valve means is moved from said closed position to said open position; and hydraulic damping means associated with said valve means for restricting fluid flow between said passageway and said chamber for damping the movement of said valve means as said valve means is moved from said closed position to said open position whereby the opening of said valve means is precisely controlled.
