Abstract
An improved sprinkler distributor dampener utilizes at least one magnet and an electrically conductive material arranged so as to create an eddie current. The sprinkler is configured with a nozzle that directs fluid at the distributor. The distributor is configured to spin or rotate from the force of the fluid spray and thus distribute fluid in a randomized pattern. The dampener controls the speed of rotation of the distributor, which is preferably a distribution disc.
Claims11
A sprinkler having a nozzle and a distributor, wherein said distributor is configured to distribute fluid sprayed from said nozzle and to rotate from fluid impinging on said distributor, wherein said sprinkler comprises an eddy current dampener configured to slow the speed of rotation of said distributor, wherein said eddy current dampener comprises at least one magnet and an electrically conductive material, wherein one of said at least one magnet or said electrically conductive material is connected to said distributor so as to rotate when said distributor rotates, wherein said eddy current dampener is configured such that rotation of one of said magnet and said electrically conductive material induces an eddy current between said magnet and said electrically conductive material when said distributor rotates thus dampening the rotation of the distributor.
