A reservoir dispenser for a bidet apparatus includes a housing unit having a first chamber and a second chamber, wherein the first chamber can hold liquid wash solution separate from the second chamber. The first chamber can include a lid with an opening therein; an activator located within the opening of the lids; and a stem and end piece located within the first chamber. The second chamber can include a water inlet and a water outlet for flow of water through the apparatus. Located between the first and second chamber is a check valve, which allows for the controlled transfer of liquid wash solution from the first chamber to the second chamber.

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 composite nozzle comprises: a housing having formed at one side thereof a cleaning liquid inlet through which the cleaning liquid is introduced, an installation port communicating with the cleaning liquid inlet at the other side thereof, and an air inlet path communicating with an air inlet on the outer side of the installation port; an opening and closing valve installed so as to be slidably movable toward one side and the other side in the installation port formed in the housing; an elastic body such as a spring that slidably moves the opening and closing valve while elastically supporting the opening and closing valve; and a cap which sprays the cleaning liquid to the outside from the other end of the housing in which the opening and closing valve is installed so as to be slidably movable in one direction and the other direction of the installation port.

A rotating sprinkler for irrigation is disclosed. The sprinkler can include a stator spaced upstream from a turbine to form a mixing region therebetween. The stator can define a primary flow path and a bypass flow path. The primary flow path is aligned relative to the plurality of blades so that water exiting the primary flow path traverses the mixing region and impinges on the plurality of blades at a first angle of attack. The bypass flow path is aligned relative to the primary flow path so that water exiting the bypass flow path intersects the water exiting the primary flow path in the mixing region to cause the water exiting the primary flow path to impinge on the plurality of blades at a second angle of attack. The sprinkler can further include a valve configured to regulate flow between the primary flow path and the bypass flow path.

Irrigation nozzles are provided that irrigate a full circle coverage area with different maximum throw radiuses. The nozzle may include two bodies, one nested within the other, that acting together form the full circle coverage area. The two bodies collectively define an annular exit orifice with one of the bodies defining the inner radius and the other body defining the outer radius. A flow restrictable inlet may be used to adjust flow through the nozzle and to adjust the maximum throw radius. The nozzle may also include a flow reduction valve to reduce the throw radius from a maximum distance and may be adjusted by actuation of an outer wall of the nozzle. A deflector for use with an irrigation nozzle is also provided.

The invention relates to an extinguishing nozzle adapter for mounting an extinguishing nozzle on a wall, having a housing and a chamber for receiving an extinguishing nozzle, wherein the housing has an extinguishing agent connection to the chamber, via which connection the chamber is able to be pressurized with extinguishing agent, wherein the chamber is designed to receive the extinguishing nozzle in a movable manner such that the extinguishing nozzle is movable back and forth between a first, retracted position and a second, advanced position, and is moved in the direction of the advanced position when the chamber is pressurized by means of the extinguishing agent.

A rotary sprinkler riser extension kit is disclosed for use with a rotary sprinkler. The kit includes an external riser extension having an upper end and lower end, and defining a channel extending through the upper end and lower end. The channel is configured to accommodate the stem of the rotary sprinkler, the upper end is configured to attach to the cap of the rotary sprinkler, and the lower end is configured to attach to the enclosure of the rotary sprinkler. The kit also includes an internal riser extension having a height substantially equal to total length of the external riser extension, a width less than inner width of the enclosure of the rotary sprinkler, means for attaching to the geared lower end of the stem, a lower gear configured to rotate the rotary sprinkler, and means to raise the stem and channel water thereto in response to water pressure at an inlet to the enclosure.
