Number: 137/624.11
Name: Fluid handling > Systems > Programmer or timer
Description: Subject matter in which an actuating means provides (1) a continuously repetitive operation of one or more valves, (2) a single cycle of operation terminating in a position to restart an additional cycle, which cycle is more complex than a mere opening and closing of a single valve, or (3) a valve operation brought about at a particular time of day, or after a particular time delay period, following initiation of a nonfluid timer.
