A sprinkler head includes a sprinkler body, a nozzle positioned within the sprinkler body, a fixed gear coupled with the sprinkler body, a wobbler cage supported on the sprinkler body, and a water deflector plate coupled with the wobbler cage and disposed downstream of the nozzle. A brake assembly is coupled with the water deflector plate for slowing a rotating and wobbling motion of the wobbler cage and the water deflector plate. The brake assembly includes a shaft extending through the water deflector plate and a brake gear disposed at an end of the shaft, where the brake gear is engageable with the fixed gear. Among other advantages, the design eliminates the use of large fixed strut framework that creates dry shadows in the water pattern.

The present disclosure may provide a cleaning apparatus for cleaning parts. The cleaning apparatus may comprise a housing defining a washing chamber having an opening through which parts may be loaded/unloaded into the washing chamber. The cleaning apparatus may also comprise a spray system adapted to direct a washing solution to clean the part in the washing chamber. The spray system may comprise a spray array with at least one rotatable spray head. The spray head may comprise a plurality of nozzles through which the washing solution is directed to clean the part in the washing chamber. The cleaning apparatus may also comprise a closure which may provide controlled access to the washing chamber through the opening and may be movable between a closed position to sealingly close the opening and an open position so as to allow for loading and unloading of parts into the washing chamber without obstruction.

An above ground sprinkler is revealed. The ground sprinkler includes a channel controller, a housing with a driving member mounted therein, an adjustment part, a locking plate, a first cover, and a second cover. A tube is extended to form two plates with a retaining groove therebetween. A rib is disposed on an outer side of the plate. The first cover includes a column part with an insertion part while the second cover includes a tongue part. Locking parts are disposed on the insertion part. The insertion part is fitted over the plates while the ribs of the plates are locked with the locking parts. When the second cover is covered over the first cover, the tongue part is mounted into the retaining groove so that the two plates are leaning against and locked by the locking parts tightly, unable to be released.

A container cleaning device includes a mounting plate shaped for accommodating a wafer; and a nozzle assembly disposed on the mounting plate and including a base and a shell complimentarily disposed on the base. The shell includes an inlet and at least one outlet member disposed on an edge. The base includes a recess communicating with the inlet, and at least one outlet element each being inclined at a predetermined angle with respect to the shell. Each outlet member of the shell is adjacent to and communicates with the corresponding outlet element of the base.

Disclosed herein is a pool light assembly including cooling for the illuminating structure. The assembly includes a water inlet housing having a portion on the dry side and a portion immersed in the pool water. An assembly having sealing structure creates a leak proof connection with the pool wall. The submerged portion of the assembly includes a base. The base has an exterior exposed to the pool water and an enclosed interior including the illuminating structure. A notch is provided in the exterior of the base and extends into the interior for allowing pool water in the proximity of the illuminating structure. The assembly includes sealing structure for preventing water from entering electrically active elements, while allowing pool water to act as a cooling element. A retaining member locks and encourages waterproof sealing of the electrically active elements. Each of the elements is provided with structure as necessary to facilitate the free flow of water through the housing.

A horizontal sidewall sprinkler is provided which includes a sprinkler body having an inlet passage for supply of a fluid and an outlet, the outlet being closed by a sealing assembly prior to actuation of the sprinkler. The sprinkler further includes a sleeve body secured to the sprinkler body and a yoke substantially spanning a width of the sleeve body, the yoke urging a load screw against a surface of the sealing assembly facing an occupancy, and being held in place prior to actuation of the sprinkler by two levers that are joined by a soldered link. A slide plate is located near an inner wall of the sprinkler body facing the occupancy prior to actuation of the sprinkler. According to one example embodiment, a frame or two guide pins are provided for bearing and supporting a deflector. The deflector is positioned between the load screw and the sealing assembly thereby obstructing a flow of fluid from the outlet upon actuation of the sprinkler. A spring is provided in the sprinkler body, between the inner wall of the sprinkler body and pressing (1) the slide plate and (2) the frame or the two guide pins away from the inner wall. Upon actuation of the sprinkler, the levers, the yoke and the load screw are forced out of and away from the sprinkler by the force of the fluid; the spring forces the slide plate outward from the inner wall; and the force of the fluid moves the deflector away from the slide plate to a position for delivery of the fluid to the protected area.

A sprinkler assembly including a fluid deflecting structure including a plurality of spaced apart tines defining a plurality of slots. The tines include a first pair of symmetric tines and a second pair of symmetric tines disposed orthogonally to the first pair of symmetric tines. The plurality of slots includes a group of asymmetric slots each having a first portion with a constant width and a second portion with a variable width radially outward of the first portion of the asymmetric slot.

An outlet device that may be used in a shower head includes a base portion that is disposed with at least one inlet and a plurality of diversion holes. The base portion is disposed with a impeller. The impeller rotates when it is impacted by water flowing. A guard sheet is movably disposed in the base portion. The impeller is connected to the guard sheet in driving way so that the impeller rotates to drive the guard sheet to move. The guard sheet moves with respect to the base portion to control the diversion holes to outflow water in cycles intermittently. Each diversion hole is rotatably connected with an outlet nozzle. The impeller rotates to drive the outlet nozzles to rotate to outflow rotating water. The impeller and the outlet nozzles cooperate to achieve a rotating water with strong massage effect.

A concealed sprinkler includes a sprinkler body having a flow passage therethrough with an inlet end and an outlet end. A closure device is secured at the outlet end of the flow passage by a heat responsive trigger. A deflector assembly includes a deflector plate and a button secured to an upstream side of the deflector plate. The deflector assembly is movably supported to the sprinkler body by at least one arm. The button defines an aperture that extends unobstructed all the way through the button from an upstream side to a downstream side.

A nozzle assembly for spraying cooling fluid in a steam-desuperheating device, includes: a nozzle body; a plug element movably attached to the nozzle body; and a splitter member fixed to a front face of the plug element. The splitter member has at least one splitter arm extending across the flow passage formed in the nozzle body as viewed from the front of the plug element to deflect flow of fluid sprayed through the flow passage.
