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.
