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: What is disclosed is a sprinkler head having a nozzle configured for spraying a fluid, such as irrigation water, at a distribution disk. The distribution disk is configured to rotate on an upper axle. The upper axle is housed within an upper axle housing. The upper axle housing is configured to rotate about a lower axle. The dual axle provides for two different rotation axles of the distribution disk in operation. Preferably a speed control device can be positioned to control the speed of rotation of one axle or both axles.

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 an improved sprinkler utilizing a nutation mechanism. The sprinkler utilizes a race having an upper limit and lower limit. The tire is connected to the distributor. Water sprays on the distributor causing the nutation of the device in which the tire moves between the upper race and lower race limits. The sprinkler includes a separate starting mechanism on which a starting bump is positioned on a distributor support.
