In various embodiments, methods, systems, and vehicle apparatuses are provided. A system provides a gravity drive to distribute coolant oil flow including a nozzle for directing a flow of coolant oil over a surface of an electric motor wherein the flow of the coolant oil is caused by a gravity drive; a connector that is coupled to the nozzle that enables the nozzle to sway in response to external forces encountered by a vehicle operation and to distribute coolant oil over the exterior surface of the electric motor; and a counterweight that is coupled to the nozzle that provides a countermeasure to the external forces encountered by the vehicle operation to cause the nozzle to sway in a manner that enables the coolant oil distributed evenly across the exterior surface of the electric motor.

What is disclosed is an improved sprinkler utilizing a nutation mechanism. The sprinkler utilizes a race having an upper limit and lower limit. The tire is connected to the distributor. Water sprays on the distributor causing the nutation of the device in which the tire moves between the upper race and lower race limits. The sprinkler includes a separate starting mechanism on which a starting bump is positioned on a distributor support.

A sprinkler head includes a sprinkler body, a nozzle positioned within the sprinkler body, a fixed gear coupled with the sprinkler body, a wobbler cage supported on the sprinkler body, and a water deflector plate coupled with the wobbler cage and disposed downstream of the nozzle. A brake assembly is coupled with the water deflector plate for slowing a rotating and wobbling motion of the wobbler cage and the water deflector plate. The brake assembly includes a shaft extending through the water deflector plate and a brake gear disposed at an end of the shaft, where the brake gear is engageable with the fixed gear. Among other advantages, the design eliminates the use of large fixed strut framework that creates dry shadows in the water pattern.

An outlet device that may be used in a shower head includes a base portion that is disposed with at least one inlet and a plurality of diversion holes. The base portion is disposed with a impeller. The impeller rotates when it is impacted by water flowing. A guard sheet is movably disposed in the base portion. The impeller is connected to the guard sheet in driving way so that the impeller rotates to drive the guard sheet to move. The guard sheet moves with respect to the base portion to control the diversion holes to outflow water in cycles intermittently. Each diversion hole is rotatably connected with an outlet nozzle. The impeller rotates to drive the outlet nozzles to rotate to outflow rotating water. The impeller and the outlet nozzles cooperate to achieve a rotating water with strong massage effect.

A sprinkler assembly with a nutating distribution plate that tilts and/or rotates upon water impinging the distribution plate. A deflector assembly includes the distribution plate and a base. A body of the sprinkler assembly includes a base retainer surface and a flanged bolt which combine to create a portion of a confinement structure. A portion of the deflector assembly is located within the confinement structure to limit a range of movement of the distribution plate. A nozzle subassembly includes a nozzle and retainer supporting a seal. The nozzle alone or in combination with the retainer can be removed from the sprinkler assembly. The sprinkler assembly can be disassembled and reassembled with minimal tools and effort for servicing. The distribution plate and the base can have mass properties optimized to improve sprinkler performance by reducing vibration, improving uniform water distribution, and reducing fine water droplet generation upon water stream impingement on the distribution plate.

What is disclosed is a sprinkler head having a nozzle configured for spraying a fluid, such as irrigation water, at a distribution disk. The distribution disk is configured to rotate on an upper axle. The upper axle is housed within an upper axle housing. The upper axle housing is configured to rotate about a lower axle. The dual axle provides for two different rotation axles of the distribution disk in operation. Preferably a speed control device can be positioned to control the speed of rotation of one axle or both axles.

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.

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.

A sprinkler assembly can include a water inlet and a nozzle assembly. The nozzle assembly can include a nozzle tube having a nozzle positioned at the downstream end of the nozzle tube. The sprinkler assembly can include a user replaceable wear disc at least partially surrounding the nozzle tube. A deflector assembly can be connected to the nozzle assembly and can include a distribution plate positioned downstream of the nozzle and configured to deflect water from the nozzle. The deflector assembly can include a cage having one or more arms connected to the distribution plate and extending from the distribution plate toward upstream end of the nozzle tube. The deflector assembly can include an upstream collar portion connected to the at least one arm and having one or more load surfaces configured to contact the wear disc, wherein the wear disc is configured to bear at least a majority of a weight of the deflector assembly.

An improved nozzle assembly for use with a sprinkler body. The nozzle assembly has a nozzle body having a nozzle insert bore and defining a fluid flow path through the nozzle assembly. A nozzle insert is positioned in the nozzle body and retained within the nozzle assembly. The nozzle insert is rotatable between operating positions. In some embodiments, a spring biased detent and detent notches index the nozzle insert at one of a series of operating positions. The nozzle insert is rotatable between the series of operational positions including the IN (or insertion) position, the RUN position, the OFF position, the FLUSH position, and the LINE FLUSH position. In an alternate embodiments the nozzle insert has detents on a circumference of the nozzle insert. A magnet is positioned in or attached to the nozzle insert. A second magnet is positioned in or attached to the body of the nozzle assembly. The detents are configured to align with detent notches in a faceplate of the nozzle assembly body. When the detents are aligned with the detent notches, the attractive force between the two magnets retains the nozzle insert in one of the operating positions in the nozzle insert bore.
