ABSTRACT:
An improved liquid flow mechanical diverter valve of the stream interaction type is provided. The valve includes a housing having an inlet for receiving a flow of liquid from a liquid source, a pair of first channels communicating with the inlet, each having an exit port, an interaction chamber, a pair of converging second channels between the exit ports and the interaction chamber, three exit areas directed away from the interaction chamber and two flapper assemblies, each having a first portion large enough to seat against and cover a first channel exit port, a second portion at an angle to the first portion and rigidly secured thereto, a pivot at the junction of the first and second portions, the second portions being spaced from and directed toward each other. A spring is associated with the second portion to urge the second portion away from the valve housing a sufficient distance to have the first portion seated against the first channel exit port, said spring having a force insufficient to prevent flow water through the exit port. A pivotal arm assembly having three positions movable by a mechanical push-pull actuator such that in only two of the positions the assembly selectively registers with one of the second portions to act as a stop to retain the first portion seated against the exit port during a predetermined period of time of liquid flow through the inlet.
