Abstract: What is disclosed is a pressure regulator having a mechanism to turn fluid flow through the pressure regulator on or off. The pressure regulator incorporates an actuator by which fluid flow to a pressure chamber that controls the linear movement of a flow tube is selectively actuated from one of a downstream supply and a pressurized fluid supply, such as an upstream supply. The actuator can be a manual, electromechanical, hydraulic or other form of actuator.

Abstract: What is disclosed is a sprinkler apparatus and system for distributing a liquid preferably for use in an irrigation system. The sprinkler apparatus utilizes removable, replaceable, and interchangeable nozzles that are configured to vary the flow and/or location of a spray of water from the nozzle at a distributor. The distributor is configured to rotate to distribute the liquid flow from the distributor in a plurality of directions. The distributor utilizes a motor to control the flow of liquid from the distributor. Preferably a sprinkler is provided with multiple nozzles such that a user and/or consumer can select which nozzle flow is desired for implementation in a given situation.

Abstract: A sprinkler head with a nutating water distribution cage attached to a sprinkler body. Water from the sprinkler head impacts a strike plate of the cage to initiate nutation of the cage. Spiral grooves on the strike plate contribute to the nutation of the cage, and an upturned edge on the periphery of the strike plate contributes to the spread and uniform distribution of water from the sprinkler head.
