Abstract: A flow control device includes a housing having a primary inlet, a secondary inlet, and an outlet disposed downstream of the primary and secondary inlets. The flow control device further includes a chamber defined by an inner circumferential surface of the housing. The chamber fluidly connects the primary and secondary inlets with the outlet. A valve member is mounted in the chamber to pivot toward and block the primary inlet by fluid pressure in the secondary inlet when fluid pressure into the secondary inlet is higher than fluid pressure into the primary inlet.
