A reservoir dispenser for a bidet washing apparatus includes a housing unit having a first chamber and a second chamber; a lid with an opening therethrough; an activator, wherein the activator is located within the opening of the lid; a stem having a stem top end piece in the first chamber and a stem bottom end piece in the second chamber; and a connecting tube, wherein the tube is permanently or reversibly attachable to the second chamber, wherein the connecting tube includes a water inlet, a choke, a suction tube, and a water outlet, wherein the water inlet, choke, suction tube and water outlet are in fluid communication with the second chamber.

A rotating sprinkler for irrigation is disclosed. The sprinkler can include a turret and a stream conditioner positioned in the turret. The stream conditioner can include a plurality of fins forming a plurality of flow regions. One or more of the plurality of flow regions can have a cross-sectional flow area that decreases in a downstream direction towards the primary port so as to accelerate the pressurized water through the stream conditioner. The plurality of fins can further straighten the water.

An oscillating sprinkler assembly includes a body including an inlet configured for connection to a water supply; a riser movably mounted in the body and movable from a retracted position to an extended position; a nozzle housing rotatably mounted on a top of the riser; a pressure regulating assembly mounted at an inlet of the riser and operable to control pressure of water into the riser based on an downstream pressure; a water turbine mounted downstream of the pressure regulating assembly such that water from the pressure regulating assembly passes through the water turbine to rotated one or more blades thereof, wherein the one or more blades are operatively connected to the nozzle housing and drive rotation of the nozzle housing; and a bypass valve, provided between the pressure regulating assembly and the water turbine and operable to control water flow to the water turbine.

A mechanism is described to resist or prevent rotation of portions of an irrigation sprinkler riser when in its lowered or popped-down position. Hence, when a pedestrian walks over a lowered sprinkler or a lawn mower rolls over a sprinkler, for example, the riser will remain fixed in its rotational orientation relative to its outer body and surroundings. By resisting or preventing this rotation, this rotational locking mechanism prevents damage to the internal transmission, gears, and arc trip mechanisms of the sprinkler, as well as prevents the watering arc from being accidentally adjusted.

A reservoir dispenser for a bidet washing apparatus includes a housing unit having at least one chamber, wherein the at least one chamber is capable of holding a liquid wash solution; a water inlet, a connecting tube, and a water outlet, wherein the water inlet, connecting tube and water outlet are in fluid communication, wherein the connecting tube is located between the water inlet and the water outlet, wherein the connecting tube includes a choke, and wherein the water inlet, connecting tube, and the water outlet are connectable to the housing unit; and a suction tube located between and in fluid communication with the at least one chamber and the choke.

A sprinkler assembly including a pressure regulator and a flow stop element combined in a single assembly. In one embodiment, the sprinkler includes a sprinkler body in fluid communication with a water supply to provide water to the sprinkler, a riser movably mounted in the sprinkler body and in fluid communication with the sprinkler body such that the riser rises up and out of the sprinkler body when water is provided to the sprinkler, a nozzle assembly mounted on a top end of the riser and in fluid communication with the riser; and a regulation element mounted in the riser and in contact with a portion of the nozzle assembly. The nozzle assembly holds the regulation member in an open position to allow flow of water to the nozzle assembly and to maintain a substantially constant water pressure in the nozzle assembly.
