Sprinkler head for efficiently watering curved landscapes

摘要

A new sprinkler head that can optimally water curved landscapes is presented here in. Existing sprinkler heads although perform well for regular landscapes, are not efficient when used across curved landscapes. The proposed inventive sprinkler has an inbuilt mechanism that can take into account the curvature of the landscape and thus optimally water the curved landscapes. In the preferred embodiments, the sprinkler head has a plurality of radially directed output ports or orifices. Each such output port is associated with a corresponding control channel and a blocking device which may be in the form of a threaded screw. The extent of insertion of the blocking device within each flow channel determines the flow discharge and hence the water throw distance (i.e., radius of water arc) from the corresponding outlet port. The flow in each output port can thus be independently and variably controlled from zero flow to full flow. These two end flow conditions will reflect in the radius of the water arc to correspondingly vary from zero to a maximum, for a constant water pressure in the pipe.
