What is disclosed is a self governing speed control device for controlling the rotation speed of a sprinkler turbine. The device has a housing that houses a viscous fluid. An axle extends into the housing and is configured to rotate in the housing. The axle is fixedly attached to a primary drum that rotates with the axle. One or more hinge pins extends from the primary drum. A brake shoe is positioned on the hinge pin. The hinge pin passes into a slot in an actuation drum configured to rotate on the axle. The brake shoe is configured to expand and contract based on the speed of rotation of the axle in relation to the speed of rotation of the actuation drum.

A high pressure nozzle, including a longitudinal housing having a liquid inlet end and a liquid outlet end opposite to the liquid inlet end and comprising an internal channel running from the liquid inlet end to the liquid outlet end, a nozzle head support shaft, rotatably arranged partially in the internal channel and comprising a liquid channel in fluid communication with the internal channel, and a rotary nozzle head supported on the nozzle head support shaft and arranged outside the housing, wherein the rotary nozzle head is arranged to rotate about a longitudinal axis of rotation to provide a rotating spraying of liquid jetted from the rotary nozzle head. The high pressure nozzle includes an axial pressure compensator arranged in the internal channel, wherein the axial pressure compensator is arranged to substantially compensate axial pressure force from liquid entering the channel at the liquid inlet end.

A sprinkler includes a pop-up deflector plate that is engageable with a brake assembly in an extended position. A brake module is secured to a sprinkler body and includes a rotatable connector coupled with the brake assembly. The pop-up deflector plate is disposed adjacent the nozzle and engages the rotatable connector in the extended position.

A lawn sprinkler is provided that restrains a hydrodynamic water discharge from a flailing fluid nozzle in a manner adapted for distributing watering a user-defined area. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

A method of processing a workpiece includes supporting the workpiece on a tailstock extending along an axis, thermally processing the workpiece with a processing device, and displacing a portion of the tailstock assembly in response to thermal expansion of the workpiece as a result of processing with the thermal processing device.

An electrically powered, portable fluid dispenser that includes a main housing and extendable wand that when used in conjunction with an electric motor, a self-feeding tentacle pumping spinning element, tentacle feed tube, and focusable vibrating backstops, is able to pump, atomize, and dispense, low and high viscosity fluid with controlled directionality and droplet size.

The mist generating device includes a housing 11 having a water tank 12; a shaft portion 13 provided in the housing and extending in a vertical direction; an impeller 14 disposed on the shaft portion to be rotatable by means of the motor in a horizontal direction about a rotation axis that is the shaft portion; a nozzle 15 for jetting the water in the water tank toward the impeller; and a pump 21 for delivering the water in the water tank to the nozzle. The impeller includes a plurality of blades 14a arranged along a rotation direction of the impeller and configured to collide with the water jetted from the nozzle. The water jetted from the nozzle collides with the blades to thereby smash the water and generate mist. The housing includes a mist releasing port 18 for releasing the mist generated in the housing outwardly of the housing.

A viscous damped deflector in accordance with an embodiment of the present disclosure includes at least one sloped spiral rim extending from a lower surface of a top of the viscous damping chamber that rotates with the rotating distributor of the damped deflector, such that viscous fluid in the chamber is pumped to the center of the chamber as the distributor rotates.

A sprinkler head for irrigation having a sprinkler body. The sprinkler body surrounds a fluid delivery tube. The sprinkler body includes an upper plate and a lower plate. A and exits out the fluid nozzle. A fluid distribution cage is positioned on the sprinkler body and around the fluid delivery tube. The fluid distribution cage has one or more arms connecting an upper plate and a lower plate. The lower plate is configured to direct fluid sprayed onto it from the fluid delivery tube. When fluid is sprayed on the lower plate the upper plate begins to nutate around the fluid delivery tube between the upper sprinkler body plate and lower sprinkler body plate. The upper and lower sprinkler body plates have races configured for receiving one or more resilient cushions positioned on the upper plate of the fluid distribution cage. The upper cage plate or the lower sprinkler body plate has one or more projections positioned such that the fluid distribution cage hangs at an angle to facilitate initiation of nutation of the fluid distribution cage.
