Abstract
An apparatus and method for dispensing water in a radially uniform distribution over a surface. The reciprocating sprinkler device includes a housing, an inlet port for receiving water under pressure to the housing, at least two outlet ports capable of dispersing water in differing directions, and a reciprocating water driven valve. Each outlet port includes an opening for receiving water from within the housing. The reciprocating valve alternately covers portions of the outlet port openings as it moves, thereby modulating the flow of water between the outlet ports resulting in increasing and decreasing flows of water across a surface.
