摘要： A variable arc spray nozzle is provided for delivering irrigation water to a surrounding terrain area in a spray pattern of variably adjustable arcuate width. The spray nozzle is adapted for mounting onto the upper end of a water supply riser, and includes a rotatable adjustment collar which cooperates with an upper deflector to define a discharge orifice of variably selected arcuate width. A stabilizer vane on the adjustment collar protrudes generally upstream at the adjustable side edge of the discharge orifice to tailor the associated side edge of the resultant spray pattern for improved water distribution and range. The deflector additionally includes a substantially horizontal step formed at the upstream side of the discharge orifice to produce a localized pressure loss resulting in improved water distribution across the variable width of the spray pattern. This horizontal step leads to a radially outwardly inclined deflector surface which is interrupted by a substantially vertical step at the downstream side of the discharge orifice for increasing the trajectory and range of throw for the discharged water stream.

摘要： An adjustable riser is provided for coupling an irrigation sprinkler to a water supply line, wherein the riser is adapted for quick and easy longitudinal adjustment to variably select the elevational position of the sprinkler relative to ground level. The adjustable riser comprises a pair of telescopically interfitting inner and outer riser tubes coupled respectively to the sprinkler and to the water supply line. The inner riser tube has a keyway formed on the exterior surface thereof, and the outer riser tube carries at least one key protruding into and engaged with the keyway. In the preferred form, the keyway comprises at least one recessed channel defined by an axially spaced succession of part-circumferential segments interconnected at opposite ends by axial segments extending in opposite directions. This channeled keyway permits longitudinal adjustment in riser length by displacement of the outer riser tube relative to the inner riser tube in a sequence of back and forth part-rotational steps with intervening axial steps, with the key tracking along the keyway to prevent full circle rotation of the outer riser tube relative to the inner riser tube.

摘要： An improved locking assembly is provided for releasably locking a valve unit incorporated into a sprinkler housing or the like, wherein the locking assembly prevents the valve unit from being driven from the housing as a projectile by water under pressure at the upstream side of the valve unit. The valve unit includes a mounting ring normally held seated upon a shoulder seat within the base of the sprikler housing by the locking assembly including a stacked pair of snap rings installed into an enlarged housing lock groove thereby positioning a movable valve member in association with a valve seat to control water flow into the sprinkler housing. The valve unit is removable from the housing, for example, for maintenance purposes by removing the two snap rings one at a time. In the event the first snap ring is removed without prior relieving of water pressure at the upstream side of the valve unit, the water pressure lifts the valve unit from the valve seat to permit water flow into the housing while the second snap ring remains locked within the lock groove to block valve unit removal. When the water flow is turned off, the valve unit is removable quickly and easily by removal of the second snap ring.
