A manual check valve for use when priming a fluid supply for a spray gun includes an orifice that opens from the fluid supply into a storage chamber, the storage chamber captures any fluid that is expelled from the fluid supply during priming, and the storage chamber is sealed with a closure. Sealing the storage chamber traps any expelled fluid in the storage chamber and prevents any of the expelled fluid from leaking onto another surface, which keeps the priming operation clean.

A spraying device, which includes a spraying mechanism and a rotating mechanism is disclosed. The rotating mechanism includes a rotating sidewall, which sidewall is provided with multiple sets of spraying holes arranged along the circumference of the rotating sidewall. Each set of spraying holes includes a plurality of spraying holes, and the spraying holes of at least two adjacent sets of spraying holes are arranged in a staggered arrangement. The spraying mechanism includes an infusion channel, the sidewall of which is provided with a spraying spout. The infusion channel extends along the inside of the rotating sidewall, the rotating sidewall being configured to rotate or swing with respect to the spraying spout of the infusion channel.

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.

A sprinkler head having a spool assembly positioned within the lower sprinkler body of the sprinkler head. The spool assembly has a spool body having a distribution disc at an upper end of the spool body. The sprinkler head is configured with a nozzle that sprays fluid onto the distribution disk, causing the spool assembly to nutate within the lower sprinkler body when sprinkler head is running. The spool assembly is configured with two friction bands that are each configured to radially roll in or on a respective race within the lower sprinkler body. The friction bands can be integrally formed with the spool assembly or removably positioned on the spool assembly.

A system and method for the application of friction-modifying coatings to roadways, walkways, and other areas subject to vehicular, human or animal traffic, the system and method comprising the controlled, simultaneous application of binder and filler to a surface of a substrate, using a mobile device which passes over the substrate as the binder and filler are being applied. The system includes a mobile platform configured for being coupled to a vehicle. A binder applicator is mounted on the mobile platform and coupled to a resin container. A plurality of openings is linearly arranged into two rows extending along the length of the binder applicator. An air knife is mounted on the mobile platform and coupled to an air compressor for generating an air curtain. An aggregate dispenser bar including at least one aggregate dispenser is coupled to an aggregate bin and mounted on the mobile platform for dispensing aggregate.
