ABSTRACT:
A shuttle valve (12,150,230) is provided having a body (44,152,232) defining an interior chamber (46,154,234). The valve (12,150,230) includes inlet (16,158,238), outlet (18,160,240) and common (14,156,236) ports that are coupled to the body (44,152,232). A shuttle (48, 162,242) is translatably disposed within the chamber (46,154,234) between a first position wherein the inlet (16,158,238) and common (14,156,236) ports are fluidicly coupled and the common (14,156,236) and outlet (18,160,240) ports are fluidicly uncoupled, and a second position wherein the outlet (18,160,240) and common (14,156,236) ports are fluidicly coupled and the common (14,156,236) and inlet (16,158,238) ports are fluidicly uncoupled. A first check valve (50,50,50) coupled to the inlet port (16,158,238) to permit fluid flow through the inlet port (16,158,238) into the chamber (46,154,234) and to prevent fluid from discharging therethrough. A second check valve (50,50,50) is coupled to the outlet port (18,160,240) in a manner to permit fluid to discharge from the chamber (46,154,234) through the outlet port (18,160,240) and to prevent fluid from flowing through the outlet port (18,160,240) into the chamber (46,154,234).
