Abstract
A three way check valve for a vehicle fluid pressure braking system includes a housing having first, second and third inlet ports and an outlet port. A pair of shuttles are slidably mounted in the housing, and are responsive to variations in the fluid pressure at the first, second and third inlet ports to communicate the inlet port having the highest pressure level to the outlet port, and to terminate communication through the other inlet ports to prevent back-flowing from one inlet port to the other inlet port.
