SELECTABLE VALVE ASSEMBLY FOR A VEHICLE TRANSMISSION |
摘要 |
A hydraulic valve assembly for controlling a clutch in a vehicle transmission. The valve assembly includes a housing with a first port for connection to a source of pressurized hydraulic fluid, a displaceable sealing piston disposed within the housing, a valve spring for displacing the sealing piston, a snap-spring having first and second equilibrium positions, and an overstroke spring. In the first equilibrium position a spring force displaces the sealing piston to uncover the first port to enable fluid flow through the valve, and in the second equilibrium position the valve spring displaces the sealing piston to block the first port to block fluid flow through the valve. Moving from the first equilibrium position to the second equilibrium position includes displacing the overstroke spring. |
