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

Abstract: A finger rest for a liquid applicator is presented. The finger rest comprises a base. The finger rest also comprises an aperture configured to receive a handle of the liquid applicator. The base is configured to rotationally align with a head of the liquid applicator at a junction.

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 line striper is disclosed. 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: The present disclosure generally relates to a sprayer for a fluid delivery system. In one example, a sprayer for a fluid delivery system is provided. The sprayer includes a main body having a handle and a trigger. The sprayer also includes a spray head having a fluid input for receiving fluid material and a fluid output for spraying the fluid material. The spray head is removably couplable to the main body by rotating the spray head with respect to the main body to engage a connection component of the spray head to a corresponding connection component of the main body. The sprayer also includes a spray head locking mechanism on the main body that extends to engage a portion of the spray head.

Abstract: A reversible, multiple spray tip spray gun tip assembly includes a tip holder and a turret. In one embodiment, the tip holder has a turret opening and a fluid spray passage that is in communication with the turret opening. The turret has a barrel including a plurality of spaced apart spray tips and a handle to rotate the barrel within the turret opening. Either the tip holder or the turret includes one or more projections while the other of the tip holder or the turret includes a cam surface with which the one or more projections slideable engage such that rotating the turret relative to the tip holder causes the turret to translate relative to the tip holder and to align each of the spray tips with the fluid spray passage in a spray position and a clear position.

Abstract: The present disclosure generally relates to fluid sprayers and more specifically, but not by limitation, to a portable airless fluid sprayer including fluid container support features configured to accommodate fluid containers of different sizes. In one example, a fluid sprayer pump assembly is provided and includes a pump assembly housing and a fluid intake conduit configured to provide a fluid path to the pump assembly housing. The fluid sprayer pump assembly also includes a frame assembly supporting the pump assembly housing and including a plurality of fluid container support features. Each of the fluid container support features is configured to accommodate a respective fluid container such that an inlet end of the fluid intake conduit is positionable within the respective fluid container. In one example, a fluid container support feature includes a fluid container holder pivotably attached to the frame assembly and movable between first and second positions.

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: Apparatus for securing and selectively releasing a piston pump from a drive assembly including two collar segments, with one segment fixed to the drive assembly and the other segment movable only linearly transversely with respect to a longitudinal axis of the piston pump, with an over-center mechanism to lock the movable segment via a pair of links. The piston is engageable and disengageable with a drive mechanism in the drive assembly via a pair of interengaging surfaces, with one C-shaped member receiving the other member which is T-shaped.

Abstract: A texture spray pump unit (100) having a tank (140) with an outlet for providing texture material to a pump (120), for delivery to a texture spray gun. The spray pump unit (100) also has an air source (180) for providing power to the pump (120) and air to deliver the texture material from the gun. A frame supports the tank (140), air source (180) and pump (120). The tank (140) is removable from the frame, and has a self closing valve to block leakage from the tank (140) when removed from the frame. The valve may have a pair of helper springs urging the valve closed. Mating portions on the frame and tank (140) guide engagement of a tank outlet with a pump inlet tube.

Abstract: A conventional liquid spray gun having a compressed air supply equipped with a liquid, e.g. paint, container for supplying the liquid to be sprayed onto a target surface. The container has a closed bottom, an open top and a cylindrical sidewall. A removable cover is attached over the open top of the container, and the cover has a pair of apertures extending through it, one of which holds a proximal end of a rigid tube whose distal end extends to a point close to the container's bottom. Slidingly mounted on the rigid tube is a generally circular, movable plunger whose periphery engages the cylindrical sidewall of the container. Pressurized air injected through the second aperture in the cover forces the plunger against the liquid's surface and causes the liquid to flow through the lumen of the rigid tube to the liquid inlet port of the spray gun.
