ABSTRACT:
A selectively operated multiple output flow distributor includes a circular head block having a central input port and a plurality of peripherally spaced outlet ports terminating in a valve seat. A resilient circular diaphragm underlies the head block and is provided with raised valve-defining bosses registering with the outlet ports, and its border is sandwiched between the confronting peripheral border of the port block and an underlying block slidably carrying valve stems registering with each of the bosses and either spring-urged to a raised valve-closing position or unbiased to be retracted normally from the port in a valve-open position. A mechanism including either motivating solenoids or a hand or motor-controlled circular cam selectively actuates the valve stems to open or close respective valves.
