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.

Abstract: A combination check-flow control and selector valve that distributes fluid from a single inlet sequentially out through a plurality of outlets. The valve includes a housing with a selector chamber having a centrally located inlet and a plurality of outlets, a replaceable sequencing cam adjacent the top of the housing, a check-flow control valve means movable into and out of an inlet, and a selector valve including a sequencing sealing means rotatable and movable toward and away from the outlets. The selector valve is connected to the replaceable cam to direct the step-by-step movement of the sequencing sealing means in response to a minimum of fluid flow rate through the inlet as well as large fluid flow rates. The check-flow control valve means moves the sequencing sealing means into position adjacent the outlets just as it moves downwardly out of the inlet. The force and weight of the fluid acts on the sequencing sealing means to seal a plurality of the outlets.

Abstract: The present invention relates to an improved sequencing disk means for fluid handling in a sequencing valve having a plurality of outlets. Sequencing valves deliver fluid from the inlet sequentially out through one or more fluid outlets in a predetermined sequencing cycle. The sequencing disk means reciprocates and rotates to sequentially deliver fluid under both high or low fluid flow rates from an inlet to a plurality of discharge outlets. The improved sequencing disk means includes a main sealing means, a stem connected to the main sealing means, and a generally cup-shaped check valve means with a relatively small opening in the bottom of the cup-shaped portion. The stem and check valve means includes connecting means that cooperate to fix the stem relative to the main sealing means or sequencing disk.
