Abstract
A sprinkler unit comprises a housing having an inlet for connecting to a source of water, an outlet, passage means connecting the inlet to the outlet, a nozzle detachably mounted in the outlet for distributing a stream of water outward from the housing, and a valve in the passage selectively operable for selectively stopping flow of water through the passage means to the nozzle and an actuator operable from the exterior of the housing for selectively operating the valve.
Claims18
A sprinkler unit comprising:
- a housing having a central axis and an inlet for connecting to a source of water, an outlet, passage means including a coaxial portion connecting said inlet to said outlet, said outlet having means defining a nozzle receiving socket;
- a nozzle for detachably mounting in said outlet for distributing a stream of water outward from said housing;
- and
- a valve in said coaxial portion of said passage means and selectively operable for selectively stopping flow of water through said passage means to said nozzle;
- and
- actuator means on a top of said housing and extending at least partially along said coaxial portion of said passage means and operable from the top exterior of said housing for selectively operating said valve.
