Nutating sprinkler with rotary shaft and seal |
摘要 |
A nutating sprinkler includes a body portion having a nozzle at one end and a spray plate supported thereon at an opposite end downstream of the nozzle. The spray plate has a plurality of stream distributing grooves formed on one side thereof configured to cause the spray plate to rotate when struck by a stream emitted from the nozzle. The spray plate also includes a flexible connector coupling the spray plate to a free end of a first rigid shaft seated in a housing at the opposite end, such that the spray plate is caused to wobble about a common center of motion as it rotates.
