Abstract: A check valve comprises a housing, a fluid passage, a seat, a valve member and a stop. The fluid passage extends through the housing. The seat is disposed in the fluid passage. The valve member is positioned in the passage to engage the seat. The stop extends through the housing to engage the valve member. The stop is accessible from outside the housing to adjust a distance the valve member can travel from the seat. In one embodiment, the stop includes a variable stop feature, such as an offset pin or a cam. In another embodiment, the stop includes a pump control valve. In yet another embodiment, the housing includes markings to indicate a position of the stop. The valve member comprises a ball or a poppet in different embodiments.

Abstract: A material sprayer includes a hopper module and a power module. The power module is mountable and dismountable from the hopper module. The hopper module includes a hopper frame and a hopper supported by the hopper frame. The power module includes a drive and a pump connected to and configured to be powered by the drive. The pump interfaces with the hopper with the power module mounted on the hopper frame such that the pump can draw material from the hopper.

Abstract: A sprayer includes a spray gun and a hopper. An air source provides compressed air to the sprayer to both eject fluid from the spray gun as a spray and to pressurize the hopper. The spray gun includes an airflow controller for controlling the flow of the compressed air to a nozzle of the spray gun, a pressure regulator for regulating a pressure of the compressed air flowing to the hopper, and a relief valve between the pressure regulator and the hopper. The hopper receives the compressed air through a port in the hopper, and the compressed air assists the flow of material out of the hopper and into the spray gun.

Abstract: A spray gun includes a gun body and a handle removably connected to the gun body. A filter is disposed in the handle for filtering particulate from the spray fluid. A trigger guard is connected to the handle and gun body and includes a contour on a lower portion of the trigger guard for receiving one or more fingers of the user that are not interfacing with and contacting the trigger. The trigger guard can be disconnected from the gun body and rotated relative to the handle. The trigger guard can contact a portion of the handle and exert torque on the handle to connect the handle to and disconnect the handle from the gun body. The portion of the handle at least partially covers a fitting connecting to the handle to provide spray fluid to the spray gun.

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 fluid dispensing system includes a motor housing and a piston pump assembly connected to the motor housing. A motor is mounted within the motor housing. The piston pump assembly includes a pump housing, a cartridge having a first end that extends into a second end of the pump housing, a piston that extends into a first end of the pump housing and the first end of the cartridge, and a packing stack within the cartridge and adjacent an inner surface of the cartridge and through which the piston extends. The cartridge is configured to be removed from the pump housing, and removal of the cartridge removes the packing stack from within the pump housing while leaving the pump housing connected to the motor housing.

Abstract: A transfer pump includes a drive module having electronic components and a fluid module not including electronic components. The drive module provides motive power to a pump of the fluid module to power pumping by the fluid module. The drive module is movably mounted to the fluid module at dynamic and static interfaces to power reciprocation of a pumping component of the fluid module by the dynamic interface and such the drive module supports the fluid module at the static interface.
