A wobbling irrigation sprinkler head for attachment to a water conduit has a wobbling sprinkler head facing upward from the water supply conduit. The sprinkler head has a base having an attachment portion for attaching to a water source and a nozzle mounted to the base for directing water therethrough. A wobbling water deflector head is movably attached to the base and has a water deflector pad thereon having a deflector surface of predetermined shape to deflect water being emitted from the nozzle to rotate the wobbling water deflector head. A counterbalancing skirt extends from the water deflecting head around a portion of the base and spaced from the base for rotation with a wobbling water deflector head so that counterbalancing the skirt counterbalances the water deflector head to dampen vibration forces in the deflector head. The counterbalancing skirt flares from the water deflecting head adjacent to and surrounding the base and has a plurality of open areas therein and is positioned for the balancing point of the wobbling deflector head to be below the rotation point of the wobbling deflector head.

Wobbling sprinkler head

A wobbling sprinkler head is provided, especially for use in irrigation systems such as self-propelled mechanically moving irrigation systems, in which the wobbling sprinkler head faces downward from the water supply conduit. The sprinkler head has a body having a water inlet as well as an attachment for connection to the water supply and a nozzle for directing a stream of water from the sprinkler body. The sprinkler head has one or more arms extending from the body around a water deflecting head. The water deflecting head is movably attached to the sprinkler head body and has a water deflecting surface positioned to deflect water from the nozzle and move the water defecting head. The bottom of the water deflecting surface has a protruding member extending therefrom, for interacting with a second protruding member extending from the arms of the sprinkler head body. The protruding members can have magnets of opposing polarity mounted therein. Thus, the water deflecting head has a wobbling motion while distributing water from the rotating sprinkler head to thereby vary the sprinkling action.

A pressure regulator apparatus has a pressure regulator mechanism which includes first and second housing portions, each made of substantially rigid material, such as a PVC polymer, and each housing portion having a passageway therethrough. One of the housing portions has a plurality of niches formed therein while a second housing portion has a plurality of raised wedged members formed thereon so that the pressure regulator mechanism can be placed in the two housings which can be driven together to drive the housing wedge members of one portion of the housing into the niches of the other portion of the housing. Since both housings have a cylindrical portion, the wedge members are sized to extend above the inner lip of the other housing portion to thereby require a forced expansion of the substantially rigid housing portion to drive the wedge members into the locking niches in the other housing member which simultaneously locks the pressure regulator mechanism into position in the housing.

Pressure regulator apparatus and method

A wobbling irrigation sprinkler head is provided for use on a self-propelled mechanically moving irrigation system, such as a center pivot field irrigation system having the wobbling sprinkler head facing downward from the water supply conduit. The sprinkler head has a base for attaching to a pipe or to the central water supply conduit which base has nozzle mounted therein for directing water against a wobbling water deflecting head which is movably attached to the base and supports a deflector pad. The deflector pad has a deflection surface of predetermined shape with water deflecting grooves formed therein for rotating and wobbling the water deflecting head. The deflecting head has a loose fitting sleeve portion surrounding a support arm on the base and the base has a removable nozzle insert holder having a flange to loosely hold the deflecting head thereto. A magnet is mounted in the sprinkler head base to attract a ferric metal washer mounted the sprinkler head wobbling deflecting head to tilt the wobbling water deflector head relative to the base to cock the deflector head to initiate the wobbling in the deflector head.

An irrigation spray nozzle apparatus has a base member for attachment to a water line, which has a passageway therethrough. A nozzle is attached to the base member to control water flow and to direct water from the outlet of the passageway through the base towards a water deflector pad removably attached to a water deflector pad support to spray water passing from the nozzle. At least one arm is attached to the base and to the water deflector pad in position in line with the outlet of the nozzle. The water deflector pad can be removed and a hose attached through a passageway through the pad support or to an extension on the pad support itself, to convert the spray nozzle to an irrigation hose discharge device.
