Abstract: A pump rod has a head extending from a neck, and the head is received within a drive slot of a drive link. The head includes a projection, and has an area smaller than an area of the head. The projection contacts an inner surface of the drive slot. The drive link may include a projection aligned with a centerline of the drive link. The drive link projection contacts a head of the pump rod. The projections provide a reduced contact area between the pump rod and the drive link, thereby reducing any side-loading on the pump rod and increasing a lifespan of the wear parts.
Abstract translation: 泵杆具有从颈部延伸的头部，并且头部被容纳在驱动连杆的驱动槽内。 头部包括突起，并且具有小于头部区域的面积。 突起接触驱动槽的内表面。 驱动连杆可以包括与驱动连杆的中心线对准的突出部。 驱动连杆突起接触泵杆的头部。 突起提供了泵杆和驱动连杆之间的减小的接触面积，从而减少了泵杆上的任何侧向负载并增加了耐磨部件的使用寿命。

Abstract: 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.

Abstract: 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.
