A modular spray assembly for a working machine includes a base assembly that is attached to the frame of the working machine. The base assembly includes a working fluid conduit having an open end and a closed end, and a plurality of nozzle assemblies that are attached to and are in fluid communication with the working fluid conduit. A modular component includes a nozzle assembly, a first end, and a second end. The second end of the modular component is adapted to be removably attached to the open end of the working fluid conduit so as to be in fluid communication with the working fluid conduit. The modular spray assembly also includes an open end component that is adapted to be removably and alternatively attached to the open end of the working fluid conduit or to the first end of the modular component. The open end component includes a working fluid supply pipe that is in fluid communication with the working fluid storage tank of the working machine.

The droplet discharge device includes a liquid chamber which is in communication with a nozzle and to which a liquid material is supplied, a plunger having a tip portion that is thinner than the liquid chamber and that is moved back and forth in the liquid chamber, a piezoelectric actuator serving as a drive source that operates the plunger to be moved back and forth, a lever mechanism that increases a displacement of the piezoelectric actuator, a base having a mounting surface to which the piezoelectric actuator is mounted, and a discharge control device. The lever mechanism includes an arm that is operated to perform a swinging motion by the piezoelectric actuator, and a leaf spring including ends that are linked to a lower portion of the arm and to the base, and a plunger-linked portion in a central region thereof.

A faucet having a faucet base, a water hose, a faucet head, and a chamber is provided. A water valve is provided in the chamber and includes a driving member and a control valve movable between a first position enabling mixing of water and air and a second position enabling shut-off of a water flow. The faucet head further includes a push-to-rotate member movably coupled with the faucet head to enable operating the control valve within the water valve by operating the push member from or near a side of the faucet head.

The faucet head further includes a control member movably coupled with the faucet head to enable operating the control valve within the water valve using magnets by operating the control member from or near a side of the faucet head.

A long throw Pop-Up Irrigation Nozzle assembly has no oscillating or rotating parts and includes a cylindrical body having a fluid inlet and a sidewall defining at least one fluidic circuit configured to generate a selected spray pattern when irrigation fluid flows through the body. In order to throw long distance, droplet velocity, droplet size and droplet initial aim angle determine the throw to provide a low precipitation rate (PR) for fluidic sprays. The nozzle assembly and method of the present invention achieve a PR of 1 in/hr or less and good spray distribution with a scheduling coefficient (SC) of about 1.5 without utilizing any moving components to provide a significantly more cost effective nozzle assembly, as compared to prior art rotator nozzles.

An irrigation nozzle with a rotating deflector is provided whose rotational speed may be controlled by a friction brake. The nozzle may also include an arc adjustment valve having two portions that helically engage each other to define an opening that may be adjusted at the top of the sprinkler to a desired arcuate length. The arcuate length may be adjusted by pressing down and rotating a deflector to directly actuate the valve. The nozzle may also include a radius reduction valve that may be adjusted by actuation of an outer wall of the nozzle. Rotation of the outer wall causes a flow control member to move axially to or away from an inlet.

A material supply assembly includes a valve assembly having an outer valve member and an inner valve member rotatable relative to the outer valve member. A base assembly includes an base structure and an actuator. An engagement structure is operative between the outer valve member and the actuator to prevent relative movement between the outer valve member and the actuator. A locking structure is operative between the inner valve member and the base structure to prevent relative movement between the inner valve member and the base structure. Movement of the actuator relative to the base structure moves the outer valve member relative to the inner valve member to operate the valve assembly.

A faucet having a faucet base, a water hose, a faucet head, and a chamber is provided. A water valve is provided in the chamber and includes a driving member and a control valve movable between a first position enabling mixing of water and air and a second position enabling shut-off of a water flow. The faucet head further includes a control member movably coupled with the faucet head to enable operating the control valve within the water valve by operating the control member from or near a side of the faucet head.

A nozzle comprises: a housing element, a chamber being defined inside the housing element for containing a fluid; a rotor extending along a longitudinal axis, the rotor being arranged inside the housing element so that the longitudinal axis of the rotor is tilted relative to an axis of the housing element, the rotor having a conduit through which the fluid contained in the chamber can flow out of the nozzle. The rotor is rotatably derivable about the axis of the housing element, so that the longitudinal axis of the rotor moves along a conical surface. The nozzle further comprises an anti-drip device for selectively closing the conduit of the rotor, so that the fluid contained in the chamber is prevented from exiting through the conduit when the nozzle is inactive.

The droplet discharge device includes a liquid chamber which is in communication with a nozzle and to which a liquid material is supplied, a plunger having a tip portion that is thinner than the liquid chamber and that is moved back and forth in the liquid chamber, a piezoelectric actuator serving as a drive source that operates the plunger to be moved back and forth, a lever mechanism that increases a displacement of the piezoelectric actuator, a base having a mounting surface to which the piezoelectric actuator is mounted, and a discharge control device. The lever mechanism includes an arm that is operated to perform a swinging motion by the piezoelectric actuator, and a leaf spring including ends that are linked to a lower portion of the arm and to the base, and a plunger-linked portion in a central region thereof.
