    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: A manual pump dispenser includes a plunger head reciprocable between pressure and return strokes, and a pump body having an inlet valve for inletting of liquid product during each of the return strokes. A discharge valve assembly is fitted to a spout for permitting selective outletting of liquid product through the spout during each of the pressure strokes. The spout includes a bore having a predetermined diameter, with a unitary valve disposed substantially within the bore. The unitary valve is made of a material for permitting predetermined axial, or axial and radial expansion thereof under pressure from liquid product during each of the pressure strokes for thereby allowing liquid product to be discharged through a slitted opening in the unitary valve, and enabling rapid contraction thereof against a valve seat to prevent liquid product from being discharged through the slitted opening.
