A programmable, electronically controlled sprinkler system has a hermetically sealed internal chamber which encloses all of the internal water flow, valves, mechanical and rotational components and a plurality of magnetic coupling arrangements which allow external motors to control operation of the internal mechanical components without requiring any hydraulic seals.

A rotary sprinkler in accordance with an embodiment of the present disclosure includes a riser with a nozzle assembly rotatable mounted thereon. The nozzle assembly includes a pressure regulator and flow control element.

A pressure regulator for use in an elbow connector for use with a sprinkler assembly including a pressure responsive member, movably mounted in the elbow connector and movable from an open position allowing flow of water into the sprinkler assembly and a closed position where the bottom edge of the pressure responsive member blocks the flow of water into the sprinkler assembly. The pressure responsive member is biased in the open position and moves into the closed position when downstream water pressure exceeds a predetermined value.

A rotatable sprinkler comprises a base with a continuous curved surface and a rotation element disposed rotatably and relatively to the base. The rotation element has an outlet that connects to a water source. A decorative unit is disposed on a support, part of which is located on the rotation element and the free end of which is in contact with the continuous curved surface of the base. Therefore, the decorative unit may rotate relatively to the base, or move up and down when the free end of the support is pressed against the continuous curved surface.

A programmable, electronically controlled sprinkler system has a hermetically sealed internal chamber which encloses all of the internal water flow, valves, mechanical and rotational components and a plurality of magnetic coupling arrangements which allow external motors to control operation of the internal mechanical components without requiring any hydraulic seals.

A pressure regulator for use in a sprinkler assembly including a riser and a sprinkler basket includes an outer sleeve mounted in the riser at an inlet thereof and a pressure responsive member, movably mounted in the outer sleeve and movable from an open position allowing flow of water between the top surface of the filter basket and the bottom edge of the pressure responsive member and up the riser and a closed position where the bottom edge of the pressure responsive member contacts the top surface of the filter basket to prevent water from flowing. The pressure responsive member is biased in the open position and moves into the closed position when downstream water pressure exceeds a predetermined value.

An outlet device with multilevel rotary massage water has a main body, an operating unit, a switching unit and a driver. The main body has a cavity for accommodating the driver and the cavity has inlets with at least two different directions; the water from the inlet flows into the cavity and rotates the driver; the driver rotates a massage driving outlet unit, and the direction of the flow of the massage driving outlet unit periodically changes with the rotation to form the massage water; the operating unit drives the switching unit to move so that at least two inlets are both open or one of the inlets is closed; then, the velocity of the flow in the cavity is changed, so that the rotational speed of the driver increases or decreases correspondingly and the switching frequency of the massage water also increases or decreases accordingly.

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.
