A fire-fighting appliance for distributing water droplets includes a rotating nozzle unit configured with nozzles distributed about the periphery of the nozzle unit, and a tubular element that is prepared for connection to a source of water for supply of water to the nozzles. Furthermore, the fire-fighting appliance includes a motor that is attached to the tubular element and is driven by the water pressure from the water source. The motor is rotatably connected to the nozzle unit and an adjusting device is provided for controlling the rotational speed of the motor for dispersing water droplets through the nozzles in a pulsating action.

Rotational speed of a spray arm is regulated based on centrifugal force and a liquid jet to create a variable angle corner spray nozzle. The regulator includes a weight on a pivot and a fluid jet, the weight having a curved surface to produce a variable angle corner spray nozzle depending on the weight angle. Centrifugal force created during rotation pushes the weight outward, which increases as the spray arm rotation speed increases. The liquid jet is located out from a pivot point and tends to push the weight inward. The pushing force of the liquid jet is maximum when the weight is most inward and minimum when the weight is most outward. The regulator stabilizes the arm speed at a specific speed independent from center pivot friction and the spray arm nozzle's orientation tolerance. Speed stabilizes when centrifugal force on the weight is equal to the pushing force of the fluid jet.

An oscillating spray nozzle and related methods for providing spray patterns in a variety of oscillating patterns by driving movement of the nozzle with a progressing cavity displacement motor. By varying the design of the progressing cavity displacement motor, a variety of spray pattern geometries can be generated and a speed of the nozzle as it travels through the spray pattern geometries can be controlled. The oscillating spray nozzle can include a housing enclosing a progressing cavity motor that is operably connected to a spray nozzle. The progressing cavity motor includes a rotor member that is caused to rotate and oscillate within a stator member. The rotor member is operably linked to the spray nozzle, whereby the movement of the rotor member is communicated to the spray nozzle.

A garden watering device is configured for use in handheld and ground-based operation. The garden watering device includes a device body having a water inlet and a handle. The garden watering device also includes at least one water distribution member adapted to spray in multiple patterns. In one example, the at least one water distribution member includes an elongate tube with a series of discharge outlets and a multi-pattern head with at least one flow outlet. The garden watering device also includes a flow route selector that routes water to either the elongate tube or the multi-pattern head.

A thermal sprayer system includes an injector conduit in communication with an injector and a first valve for selectively directing a coating fluid through the injector conduit. A flush fluid conduit is in communication with the injector conduit for directing a flush fluid through the injector conduit. A pressurized air conduit is in communication with the injector conduit for directing a pressurized fluid through the injector conduit.

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.

The invention relates to a sprayer, comprising an air guiding element and means for fastening the air guiding element on a fixed member of the sprayer. The fastening means comprise at least one magnetic attraction means mounted on a first component from among the air guiding element and the fixed member and at least one part made from a ferromagnetic material, which is intended to cooperate with the magnetic attraction means and which is mounted on or formed by the other component from among the air guiding element and the fixed element.

The present application belongs to fluid control equipment, in particular, relates to directional controlling mechanism of fluidic sprinkler, comprising a rear reversing mechanism, a front reversing mechanism and a signal stream switching mechanism. A limiting shift rod of the rear mechanism rotate around a locating rod as the center after touching a limiting ring, then realize the reversing of the limiting shift rod. The reverse action of the limiting rod will finally lead a reversing arm to rotate by way of driving a reversing locating block, a rear reversing rod and a front reversing rod to rotate. The rear reversing mechanism, the front reversing mechanism and the signal stream switching mechanism act together, so as to switch a left-side signal stream nozzle and a right-side stream nozzle of a fluidic sprinkler, and bring about the reversing of the rotation direction of the fluidic sprinkler. Directional controlling mechanism of fluidic sprinkler is in a stepping state respectively in the clockwise and the counter clockwise working modes, so that the impact force on a rotary body is small, critical components tend to have a longer working life, an intermediate position does not exist during the reversing of the sprinkler, and the switching of the sprinkler is stable and reliable.
