  • Patent number: 4613077
    Abstract: A sprinkler body, to be anchored in the ground or to some structure, includes a chamber and a fluid inlet to the chamber. A rotatable head assembly mounted on the body includes a ring gear within the chamber and an external head with a laterally directed nozzle for directing a stream of fluid to cover a selected area around the sprinkler. A fluid operated motor within the body chamber, driven by the fluid passing through the sprinkler, drives the ring gear through reduction gearing. A Variable flow control valve consists of a slide mounted in the head for controlling the flow of fluid to the nozzle. A programmed cam is mounted on the body and a cam follower mounted on the valve slide follows the cam to vary the valve opening in relation to the rotational position of the head relative to the body. The valve controls the volume and throw of the fluid stream so that the sprinkler covers uniformly an area of irregular noncircular configuration.
