A displacement pump is configured to mount to a drive housing. A reciprocating drive is connectable to a pump rod of the displacement pump and includes a connecting rod and a drive link that receives a head of the pump rod. A tightening ring connects the displacement pump to the drive housing to mount the displacement pump to the drive housing.

Pump mounting and driving

A battery powered fluid sprayer includes a battery mounted to a vertically extending wall of the fluid sprayer. The battery powers an electric motor to power a pump to pump fluid to a spray gun for spraying. The battery is disposed within a battery chamber enclosed by a door. The battery is suspended above a base of the battery chamber to isolate battery from any fluid that may enter the chamber.

Battery powered fluid sprayer

An unmanned aerial vehicle (UAV) includes a sprayer configured to generate a pressurized fluid flow and a nozzle configured to receive the pressurized fluid from the sprayer and to generate a spray fan to apply the fluid to a surface. The UAV includes sensors and a control unit to control both flight of the UAV and spraying by the sprayer. The fluid can be stored onboard the UAV in a reservoir or can be remotely stored and pumped to the UAV. The UAV control unit can be preloaded with a spray plan and a flight plan, or the UAV can be controlled by a user.

Unmanned aerial vehicle for painting structures

A displacement pump is configured to mount to a drive housing. A reciprocating drive is connectable to a pump rod of the displacement pump and includes a connecting rod and a drive link that receives a head of the pump rod. A flange projects from a pump body of the pump and a ring projects from the pump body of the pump. A portion of the drive housing is received in a gap between the flange and the ring.

Pump rod and driving link with side-load reducing configuration

A fluid dispensing device includes a housing and a reciprocating piston fluid pump coupled to the housing. The reciprocating piston fluid pump includes a piston disposed within a cylinder. The piston is configured to pressurize at least one pumping chamber. A motor is coupled to the housing and connected to the reciprocating piston fluid pump to actuate the piston. A wobble assembly connects the motor to the piston of the reciprocating piston fluid pump. A spray tip connected to an outlet of the at least one pumping chamber.

Portable airless sprayer

A piston rod () for a spray fluid pump includes an interior pumping chamber (), one or more channels () formed on the exterior of the piston rod, and one or more side bores () extending through the piston rod and in fluid communication with the interior piston chamber and one or more channels. The one or more channels () extend at least partially axially and are open along a length of the channel. The one or more channels are angled offset with respect to the reciprocation axis for imparting a rotational moment on the piston rod to cause rotation of the piston rod during reciprocation of the piston rod. A spray fluid pump comprising such piston rod is also disclosed.

Piston rod rotation features in a spray fluid pump

A fluid spraying system includes a displacement pump configured to mount to a drive housing. A reciprocating drive is connectable to a pump rod of the displacement pump and includes a connecting rod and a drive link that receives a head of the pump rod. A tightening ring that includes threading is configured to rotate about a cylinder of the pump and shift axially along the cylinder and engage with a bottom side of the drive housing to secure the displacement pump to the drive housing.

Displacement pump mounting and retention

A power tool battery pack enclosure is configured to be retrofittedly coupled to battery pack receptacles of a plurality of power tools, each battery pack receptacle configured to removably receive a plurality of power tool battery packs. The enclosure includes a first clamshell member and a second clamshell member configured to be coupled around at least a portion of an exterior surface of each battery pack receptacle. Each of the first and second clamshell members have a top wall portion configured to be received over the exterior surface of the battery pack receptacle and a sidewall portion that extends downward from the top wall portion over at least a portion of the battery pack housing when the battery pack is received in the battery pack receptacle. The first and second enclosure members cover at least a portion of the battery back receptacle and at least a portion of the portion of a battery pack housing while allowing the battery pack to be removed from the battery pack receptacle while the enclosure remains coupled to the battery pack receptacle.

Power tool with battery pack enclosure

A fluid spraying system includes a displacement pump configured to mount to a drive housing. A reciprocating drive is connectable to a pump rod of the displacement pump and includes a connecting rod and a drive link that receives a head of the pump rod. A tightening ring that includes threading is configured to rotate about a cylinder of the pump and shift along the cylinder and engage with a bottom side of the drive housing to secure the displacement pump to the drive housing.

A spray tip comprises a tip body, a tip piece, and a pre-orifice piece. The tip body has a fluid channel along a channel axis (A). The tip piece is disposed within the fluid channel, and has a stepped, narrowing passage that terminates in an outlet orifice. The pre-orifice piece has an inlet passage, and is disposed within the fluid channel, abutting and immediately upstream of the tip piece. The pre-orifice piece and the tip piece together define a turbulating chamber therebetween.

Spray tip and method of manufacture

A fluid dispensing device includes a housing and a reciprocating piston fluid pump coupled to the housing. The reciprocating piston fluid pump includes a piston. The piston is configured to pressurize at least one pumping chamber. A motor is connected to the reciprocating piston fluid pump to actuate the piston. A spray tip connected to an outlet of the at least one pumping chamber.
