A fluid-ejection device includes a first member having a fluid inlet; a second member that can be moved relative to the first member; and a control member arranged to be at least in a first condition, in which the control member is at least substantially inside the second member during a first stroke of the second member in which fluid flow through the second member and discharge is prevented; and a second condition, in which the control member is at least substantially outside the second member during a second stroke of the second member, allowing fluid flow through the second member and discharge. A seal member has a first surface engaged with the first member, a second surface engaged with the second member, and a third surface arranged to be engaged with the control member in the first condition.

Various disclosed embodiments include illustrative sprayer assemblies, electric motor assemblies, and vehicles with cooling assemblies for stator windings of electric motors. An illustrative sprayer assembly includes a first spray device assembly configured to receive a fluid and further configured to spray the fluid therefrom. A second spray device assembly is configured to receive the fluid and is further configured to spray the fluid therefrom. A connecting tube is fluidly couplable to the first spray device assembly and the second spray device assembly and is configured to provide the fluid from the first spray device assembly to the second spray device assembly.

A fluid discharge device includes a hollow tubular body. The hollow tubular body defines a flow channel and has a plurality of bore holes arranged along a longitudinal direction of the hollow tubular body. The hollow tubular body includes a plurality of sections, two adjacent sections of the plurality of sections are connected by a choke ring, and the choke ring has an opening to allow a fluid to pass through. In a sectional plane perpendicular to the longitudinal direction, a sectional area of the opening is smaller than a sectional area of the flow channel.

A system for controlling a ground speed of an agricultural sprayer includes a speed setting device for commanding a selected ground speed of the sprayer when operating within a speed-range mode associated with a ground speed range. The speed setting device is movable across a plurality of positions, with each position being associated with a different ground speed within the ground speed range. A maximum range speed of the ground speed range is lower than a maximum ground speed of the sprayer. As such, the system includes a speed override input device for commanding that the ground speed of the sprayer be increased to the maximum ground speed. When an override input is received from the speed override input device, the computing system controls the operation of a sprayer drive system to increase the ground speed of the sprayer from the selected ground speed to the maximum ground speed.

A water spraying assembly includes a spray unit is selectively positioned on a support surface thereby facilitating a user to stand within the spray unit. The spraying unit is fluidly coupled to a fluid source thereby facilitating the spraying unit to spray a fluid onto the user. A spin unit is rotatably coupled to the spray unit and the spin unit is selectively rotated in a first direction. The user repeatedly jumps over the spin unit when the user stands within the spray unit. A remote control is provided and the remote control is in electrical communication with the spin unit such that the remote control selectively turns the spin unit on and off.

An agricultural applicator includes a chassis supported on a ground surface and an applicator boom controllably movable with respect to the chassis about a pivot axis defined in a driving direction or suspended in a height-adjustable manner. An electronic control unit receives a sensor value regarding a current driving status of the chassis, and a dampening element is controlled by the electronic control unit based on the sensor value to dampen the movement of the applicator boom. The electronic control unit is programmed to calculate an expected driving status of the applicator based on the sensor value and variable physical parameters of the applicator, and to output a control signal to the dampening element based on an expected driving status of the applicator. The electronic control unit operably controls the dampening element to adjust dampening based upon a minimization of undesired movements of the applicator boom.

An agricultural sprayer includes a purge tank, a nozzle configured to dispense an agricultural fluid onto an underlying field, and a downstream valve configured to selectively permit the air from the main fluid conduit to flow to the nozzle. A computing system is configured to initiate a purging operation to purge the agricultural fluid present within the nozzle and, upon receipt of the input, control an operation of a main valve such that the main valve is moved to an opened position to allow the air to flow through a main fluid conduit. In addition, the computing system is configured to monitor a first air pressure associated with the purge tank and a second air pressure associated with the nozzle. Furthermore, the computing system is configured to control an operation of the downstream valve during the purging operation based on the monitored first and second air pressures.

A drying device that includes a series of hollow tube sections connected sequentially end-to-end to form a helical-shaped manifold. Each hollow tube section includes a plurality of apertures used for producing air jets. The apertures fluidly connect internal passages in the hollow tube sections to an external region surrounding the manifold. The apertures are oriented to direct the air jets toward a center region of the manifold. Each hollow tube section is oriented at an oblique angel relative to a respective reference plane to produce the helical-shaped manifold.
