摘要： A liquid delivery system includes a reciprocating drive and a liquid cylinder comprising a liquid piston, operably driven by the reciprocating drive, to pump a liquid along a flow path to a liquid applicator. The liquid delivery system includes a coupler configured to couple the liquid piston to the reciprocating drive. The coupler includes a plurality of collar elements and a biasing member configured to apply a biasing force on the plurality of collar elements to retain the collar elements in a position that forms a collar that couples the liquid piston to the reciprocating drive.

摘要： A fluid spraying system includes a fluid applicator having a tip that atomizes a fluid. The fluid spraying system also includes a pump configure to pump the fluid from a fluid source to the tip and a control system. The control system identifies at least one characteristic of the tip or the fluid and communicatively couples to the pump. The control system also controls an operating characteristic of the fluid spraying system based on a characteristic of the tip or the fluid.

摘要： A spray gun for a plural component system is provided. The spray gun includes a first component delivery line and a second component delivery line. The spray gun also includes a nozzle, configured to receive and mix a first component received from the first component delivery line with a second component received from the second component delivery line. The spray gun also includes an air purge system configured to, when the spray gun is in a non-actuated position, purge the nozzle of the first and second components and, when the spray gun is in an actuated position, aid in atomization of the mixture of the first and second components.

摘要： An applicator is presented. The applicator comprises a fluidic channel extending from a fluid inlet to a fluid outlet. The applicator also comprises a trigger. The trigger is configured to, when actuated, allow fluid to flow through the fluidic channel. The applicator also comprises an adjustable handle with a frame. The handle comprises a finger rest on a first side of the frame. The handle also comprises a grip on a second side of the frame. The second side is opposite the first side. The grip is coupled to the frame by an adjustment mechanism that, when actuated, is configured to change a distance between the finger rest and the grip.

摘要： In one embodiment, a fluid delivery system includes a motor assembly and a fluid pump assembly. The fluid pump assembly is spaced apart from the motor assembly, and at least one of the motor assembly or the fluid pump assembly is movable to change a distance between the motor assembly and the fluid pump assembly. The fluid delivery system includes a flexible linkage that couples the motor assembly to the fluid pump assembly, and is configured to transfer motion from the motor assembly to the fluid pump assembly. Further, the fluid delivery system comprises a linkage tightening mechanism configured to generate a tightening force on the linkage by biasing at least one of the motor assembly or the fluid pump assembly in a direction that increases the distance between the motor assembly and the fluid pump assembly.

摘要： An example portable fluid spraying system includes a handheld fluid sprayer. The handheld fluid sprayer includes a fluid reservoir configured to store a fluid, a pump configured to pump the fluid from the fluid reservoir to an outlet of the handheld fluid sprayer and a handle. The handheld fluid sprayer includes a first trigger proximate the handle, configured to control fluid flow to the outlet. The portable fluid spraying system includes a fluid hose having a coupling mechanism configured to removably couple to the handheld fluid sprayer proximate the outlet and a fluid spray gun. The fluid spray gun includes a gun inlet configured to couple to the fluid hose and receive the fluid from the handheld fluid sprayer, a gun outlet configured to expel the fluid in a spray pattern and a second trigger configured to control fluid flow to the gun outlet.
