Abstract
A sprinkler head includes a sprinkler body formed with a through-bore defining a flow path adapted for alignment with a nozzle bore. A nozzle carrier is mounted on the sprinkler body for linear movement across the flow path and adapted to support plural nozzles. The nozzle carrier is configured to enable any one of the plural nozzles to be aligned with the flow path. The nozzle carrier is provided with plural discrete seal pads that are selectively movable into a position covering the flow path to thereby shut off flow through the sprinkler body.
Claims22
A sprinkler head comprising:
- a sprinkler body formed with a through-bore defining a flow path adapted for alignment with a nozzle bore;
- and
- a nozzle carrier mounted on said sprinkler body for linear movement across said flow path and adapted to support plural nozzles, said nozzle carrier configured to enable any one of said plural nozzles to be aligned with said flow path, said nozzle carrier also provided with plural discrete seal pads, each selectively movable into a position covering said flow path to thereby shut off flow through said sprinkler body.
A sprinkler head comprising:
- a sprinkler body formed with a bore defining a flow path adapted for alignment with a nozzle bore;
- a nozzle carrier supporting plural nozzles slidably supported on said sprinkler body for linear movement across said flow path, thereby enabling any one of said plural nozzles to be aligned with said flow path;
- said nozzle carrier provided with plural discrete seal pads for selectively covering said flow path thereby shutting off flow through the sprinkler body;
- substantially-parallel guide rails provided on a lower portion of said sprinkler body, adapted to guide said nozzles as the nozzle carrier is moved across said flow path;
- and
- wherein an upper surface of said nozzle carrier is provided with discontinuous ribs along opposite side edges of said nozzle carrier adapted to interact with respective hooks on diametrically-opposed sides of said sprinkler body to thereby enable releasable locking of said nozzle carrier in any of plural selected positions.
3 more elements
A sprinkler head comprising:
- a sprinkler body having a center hub formed with a bore defining a flow passage with an inlet and an outlet;
- a nozzle carrier supporting two selectively usable nozzles each having a nozzle bore, said nozzle carrier slidably supported on said sprinkler body for linear movement across said flow passage, thereby enabling either of said nozzle bores to be aligned with said flow passage;
- and
- said nozzle carrier provided with at least one discrete seal pad enabling selective covering of said flow passage, thereby shutting off flow through the sprinkler body, wherein said sprinkler body has a lower portion provided with upstanding ribs adapted to be engaged by said two nozzles when either of said two nozzles is in the nozzle-installed position.

A sprinkler head comprising:
- a sprinkler body having a center hub formed with a bore defining a flow passage with an inlet and an outlet;
- a nozzle carrier supporting two selectively usable nozzles each having a nozzle bore, said nozzle carrier slidably supported on said sprinkler body for linear movement across said flow passage, thereby enabling either of said nozzle bores to be aligned with said flow passage;
- and
- said nozzle carrier provided with at least one discrete seal pad enabling selective covering of said flow passage, thereby shutting off flow through the sprinkler body, wherein nozzle cleaning posts extend from opposite sides of said sprinkler body.

A sprinkler head comprising:
- a sprinkler body having a center hub formed with a bore defining a flow passage with an inlet and an outlet;
- a nozzle carrier supporting two selectively usable nozzles each having a nozzle bore, said nozzle carrier slidably supported on said sprinkler body for linear movement across said flow passage, thereby enabling either of said nozzle bores to be aligned with said flow passage;
- and
- said nozzle carrier provided with at least one discrete seal pad enabling selective covering of said flow passage, thereby shutting off flow through the sprinkler body, wherein said at least one discrete seal pad comprises a round seal pad located between two nozzle holders and providing a first shut-off surface, and a pair of oblong seal pads located at opposite ends of said nozzle carrier, said pair of oblong seal pads having second and third shut-off surfaces and adjacent bores, respectively, said adjacent bores adapted to align with the nozzle bores of said two nozzles.
