An agricultural sprayer having a liquid supply conduit for directing selectively controllable pressurized liquid to a plurality of spray nozzle assemblies. Each nozzle assembly includes a nozzle body having a respective orifice member having an inwardly tapered conical section communicating with a smaller diameter discharge orifice. Each respective orifice member is made of a resilient and pressure responsive deformable material such that upon an increase in the pressure of the liquid supply said liquid flow passage and discharge orifice thereof can be altered to increase the rate through said orifice member and nozzle body by at least 75 percent and upon interruption of the supply of pressurized liquid to the orifice member the orifice member liquid flow passage and discharge orifice return to their original shape.

A valve including a body having an inner central orifice and a chamber, a piston formed by a rod and by a head mounted in the chamber, the rod extending outside the body and moving in a bore of an application system. The valve includes a first sealing device around the rod on one side of the valve where the rod extends outside the body, part of the chamber being filled with a pressurized control fluid to obtain movement of the piston against the force of a spring housed in the body. The valve includes a second sealing device around the rod, between the first sealing device and the chamber. The valve includes a vent duct in the rod that communicates with the inner central orifice between the first and second sealing devices and emerges in the open air or in part of the chamber communicating with the open air.

Valve for a system for applying a covering product, including projecting or recessed shapes on a peripheral part, configured to cooperate with projecting or recessed shapes of a dedicated mounting and dismounting tool, these projecting or recessed shapes of the valve being configured to transmit a rotational movement to the valve, and to be secured to the tool. The projecting or hollow shapes of the valve include a first peripheral profile having at least one planar surface, and a second peripheral profile located behind the first profile relative to an outer end of the valve. The second profile has at least one first planar surface aligned with the planar surface of the first profile, and at least one second planar surface angularly offset relative to the planar surface of the first profile, such that the second planar surface of the second profile forms a shoulder relative to the first profile.

A viewing device for a vehicle includes a viewing assistance portion configured to assist viewing by an occupant of the vehicle. A housing body houses the viewing assistance portion. An opening portion is formed in a panel member to penetrate at a peripheral portion of a main surface side of the viewing assistance portion. A nozzle in the housing body is displaceable to project/retract from the opening portion. When projecting from the opening portion, the nozzle is configured to direct washing liquid from a jetting port at a distal end portion side of the nozzle toward the main surface side of the viewing assistance portion. A cover is displaceable between a closing position and an opening position. A mechanism is operable, using a force of the nozzle being displaced, to displace the cover.

A water stream stop valve for sprinkler, comprising: a tube body; an annular cover; multiple securing units; and a drainage body having a hole at the center is arranged above the tube body by multiple support plates; whereby water stream stop valve is applied in a pop-up sprinkler, wherein the pop-up sprinkler includes: a main body; an expansion pipe, and having a stop member arranged at top internal diameter thereof; a spray head; and the water stream stop valve is arranged inside the expansion pipe and below the spray head; When the spray head falls off spray head, the water stream stop valve will be pushed up to the top of the expansion pipe and stop at the stop member for avoiding the overflow of water, maintaining the spraying at the original area, and delivering a service indication stream.

A method for shutting off water that is applied to a water outlet device, which comprises enabling a volume of a variable chamber to increase to form a negative pressure chamber to suck residual water in a water outlet chamber into the negative pressure chamber by releasing negative pressure at a connection of the variable chamber and the water outlet chamber when the water is shut off. A method for shutting off water that is applied to a water outlet device, which comprises enabling a water shut-off sealing member to hermetically seal a connection of a water outlet hole and a water outlet chamber by a volume of air in the water outlet chamber of the water outlet device increasing to generate negative pressure when the water is shut off. A water outlet device is provided.

A rotor nozzle structure has a chamber deployed with a rotor connecting to the water outlet and an adjusting element, wherein the rotor nozzle is capable of generating a directing stream and a wide-angle swirl stream, and the adjusting element is switchable by a rotational means for driving the rotor in a rotation or static status in the chamber.

A water injector assembly includes an injector body having a substantially hollow interior. The injector body defines an inlet opening defined within an outer radial surface of the injector body at a first axial location along the injector body. The injector body defines a flowpath opening in fluid communication with the inlet opening such that the flowpath opening is configured to receive the fluid from the inlet opening. The injector body defines an outlet opening defined within the injector body at a second axial location along the injector body. The outlet opening is in fluid communication with the flowpath opening, such that the outlet opening receives the fluid from the flowpath opening. The second axial location of the outlet opening is different than the first axial location of the inlet opening.
