ABSTRACT:
Apparatus for impulse spraying. A float valve is disposed at the lowest end of a liquid/gas accumulator which is connected via a connecting pipe having the float valve interposed therein to a hollow member having a vertically divided space to the upper end of which an outflow pipe leading to a sprinkler is connected. A water distribution pipe leading from a water supplying conduit is attached to the lower end of the divided space. A selectively operated shut-off valve in the hollow member is interposed between the outflow pipe and the connecting pipe, the shut-off valve functioning to shut off the outflow pipe when the water pressure in the upper end of the divided space in the hollow member is lower than that in the lower end of such divided space, and to open the outflow pipe when the pressure in the upper end of the divided space exceeds the pressure in the lower end of the divided space.
