ABSTRACT:
An improved flow sequencing and check valve which delivers a single source of fluid to a plurality of outlets. The improvement includes a generally cup-shaped portion which never disengages with the entrance port as it moves the sequencing disc closed in response to a broad range of fluid flow and pressure conditions. The cup-shaped portion is in continuous engagement with the entrance port, allowing virtually all of the fluid to pass through exit ports in the base of the cup-shaped portion and through outlet apertures controlled by deflectable flappers integral to the sequencing disc. Hence, both fluid weight and pressure continuously act upon the cup portion to seat the sequencing disc.
