摘要：An assembly for irrigating at water pressure below 10 psi comprising a sprinkler head for discharging water at a desired discharge pressure below 10 psi onto a site to be irrigated, a pressure chamber for delivering a supply of water at a supply flow rate and at a supply pressure greater than the discharge flow rate and the discharge pressure, a container structure for containing a volume of water in communication with the sprinkler head having a free surface communicating with atmosphere disposed at a level above the sprinkler head a height generally corresponding to the desired discharge pressure, and a float valve mechanism for introducing water from the pressure chamber into the container structure sufficient to maintain the free surface of the volume of water contained therein generally at the aforesaid level.
