ABSTRACT:
An improved sequencing valve of the type having a valve disk mounted within a valve housing for reciprocating and indexing movement between an inlet port and a plurality of outlet ports to couple a water supply line in sequence with a plurality of outlet conduits in response to turning on and off of a water supply. The valve disk has a flow opening therein which is closed by a spring-biased control valve when the water supply is turned on such that the valve disk is responsive to a relatively low and selected fluid pressure for movement to a position seated over the outlet ports with the flow opening in alignment with one of the outlet ports whereupon the control valve opens with increasing fluid pressure to permit water flow to the aligned outlet port. When the water supply is turned off, the control valve closes the flow opening, and water within the housing at the upstream side of the valve disk is discharged through a bleed port to a different outlet port thereby relieving back pressure on the valve disk and insuring spring-assisted movement away from the outlet ports. In a preferred form, an externally exposed selector dial moves with the valve disk to provide an externally visible indication of valve disk position with respect to the outlet ports, wherein this selector dial can be rotated when the water supply is off, to select the next outlet port to be coupled with the supply line.
