Abstract: A fluid dispenser system is disclosed herein that is configured to switch between an open position in which fluid flows through a fluid channel and a closed position in which fluid is prevented from flowing through the fluid channel. The fluid dispenser system includes a valve disposed along the fluid channel and configured to move between the open valve position and the closed valve position, a trigger actuatable between an open trigger position and a closed trigger position which move the valve between the open valve position and the closed valve position, a trigger latch configured to move between a latched position in which the trigger latch fixes the trigger in the open trigger position and an unlatched position in which the trigger latch does not constrain movement of the trigger, and a solenoid with a solenoid pin.

Abstract: A system for generating and dispensing plural component materials includes a controller operatively connected to dispense valves and return valves. The return valves are in respective open states to allow constituent materials to circulate back to a source and are in respective closed states to block circulation. The dispense valves are in respective open states to allow mixing of the constituent materials to form the plural component material and in respective closed states to prevent generation and dispense. The controller implements a delay between closing the return valves and opening the dispense valves to build pressure in the system prior to generating and dispensing the plural component material.

Abstract: A piston rod (27) for a spray fluid pump includes an interior pumping chamber (40), one or more channels (50) formed on the exterior of the piston rod, and one or more side bores (32) extending through the piston rod and in fluid communication with the interior piston chamber and one or more channels. The one or more channels (50) 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.

Abstract: A shaping air ring for a rotary bell atomizer spray device includes a plurality of circumferentially spaced nozzles disposed in the shaping air ring, wherein each nozzle has a mix chamber, at least one inlet on an upstream end of the mix chamber, and an outlet at a downstream end of the mix chamber. First and second air flows are provided to the mix chamber through the at least one inlet and a combined air flow is discharged through the outlet. The combined air flow shapes the spray pattern of the liquid sprayed by the rotary bell atomizer spray device.

Abstract: Apparatus and associated methods relate to remote priming of a texture sprayer. The texture sprayer includes a main unit, a hose assembly and a spray gun, the main unit includes an air compressor, a sensor that senses a parameter of air compressed by the air compressor, and a texture material pump that is activated and deactivated in response to the parameter sensed. A spray gun can be remoted coupled to the main unit via the hose assembly. The spray gun includes a nozzle, from which the texture material is forcefully expelled as a spray, a trigger, and a prime valve. Actuation of the trigger causes the spray gun to mix the compressed air with the texture material and to forcefully expel the texture material as a spray from the nozzle, thereby causing flow of the compressed air. Opening the prime valve releases the compressed air thereby causing flow of the compressed air.

Abstract: A battery powered fluid sprayer includes a shelter that the battery is mounted in to provide power to the electric components of the sprayer.
