Abstract: A fluid applicator configured to deliver fluid at a pressure is provided. The fluid applicator comprises an inlet and an outlet. The fluid applicator also comprises a fluid path extending from the inlet to the outlet. The fluid enters the inlet and exits the outlet at the pressure. The fluid applicator also comprises a trigger configured to, when actuated, facilitate the fluid flow through the fluid path. The fluid applicator also comprises a locking mechanism configured to extend through a body of the fluid applicator, and configured to transition between a locked position and an unlocked position. In an unlocked position, the trigger can actuate and, in a locked position, the trigger is inhibited from actuating.

Abstract: The line striper comprises a material deployment system configured to receive a material from a material source and deliver the received material to a deployment mechanism, wherein the deployment mechanism is configured to apply the received material to a surface. The line striper also comprises a mechanical debris removal system configured to, when actuated, move along an application path ahead of the deployment mechanism such that debris is dislodged from the surface, wherein the mechanical debris removal system comprises a contact mechanism configured to facilitate dislodging of the debris from the surface.

Abstract: A fluid applicator configured to reduce user fatigue is presented. The applicator comprises an inlet and an outlet fluidically coupled by a fluid path. The applicator also comprises a trigger. The trigger is configured to, when actuated, move between a closed position and an open position. The open position comprises a fluid flowing from the inlet, to the outlet, along the fluid path. The applicator also comprises a trigger support configured to reduce a pressure required to maintain the trigger in an open position. The trigger support is configured to reduce the pressure required as the trigger actuates between the closed position and the open position.

Abstract: A flexible paint hose has a first end, a second end, and a continuous conduit wall extending from the first end to the second end. The continuous conduit wall has a cross-section absent of an edge, and a non-circular cross-sectional shape in a first state and a substantially circular cross-sectional shape in a second state.

Abstract: A trigger locking system for a liquid applicator having a trigger with an opening is provided. The trigger locking system comprises trigger locking device configured to extend through the opening. The trigger locking device is configured to move, when actuated, between a defined locked position and a defined unlocked position. While the system is in a locked position, the trigger is nonactuable. While the system is in an unlocked position, the trigger is actuable such that, when actuated, a liquid is released from the liquid applicator.

Abstract: A plural component pump system is provided for delivering plural liquid components at a selected ratio. The pump system includes a first brushless DC motor configured to drive a first pump that pumps a first liquid component to an output and a second brushless DC motor configured to drive a second pump that pumps a second liquid component to the output. The pump system includes a first controller configured to control the first motor and a second controller configured to control the second motor. The pump system also includes a communication interface between the first controller and the second controller. The first controller is configured to send a signal to the second controller using the communication interface and the second controller is configured to control the second motor based on the signal to deliver the first and second liquid components to the output at the selected ratio.

Abstract: A fluid sprayer is provided and includes a fluid pump assembly having an outlet path and a motor assembly configured to drive the fluid pump assembly to pressurize fluid. The motor assembly is controlled by a throttle mechanism. The fluid sprayer also includes a fluid pressure control assembly including a mechanical pressure transducer configured to be displaced as a function of fluid pressure in the outlet path. The fluid pressure control assembly is configured to control the throttle mechanism as a function of displacement of the mechanical pressure transducer.
