Check-valve assembly

A compact manifold assembly that includes a check valve and an inverted shuttle valve is for full-power brake systems. The assembly is suited for hydraulic- brake systems that must store energy in two separate accumulator circuits. The inverted shuttle valve isolates the higher pressure of the two circuits, while directing lower pressure to the switch port. A check valve prevents pressure from leaking back to the inlet port. Maximum flow capacity is 11 gpm and operating pressure is 3,625 psi. Applications include split systems with a pressure-compensated pump and electrohydraulic accumulator charging controlled by a pressure transducer at the switch port.
