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 passages for providing compressed air to the nozzle for spraying and to the hopper for pressurizing the hopper. The spray gun further includes a relief valve for venting pressurized air from 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 line striper having a spray control system includes a spray gun, a lever, first and second cables, a manual actuator, and an assisted control. The lever is configured to move between a spray position and an inactive position. The first cable is mechanically linked to the lever. The manual control is mechanically linked to the first cable and configured to pull the first cable rearward to move the lever into the spray position. The second cable is mechanically linked to the lever. The assisted control is configured to pull the second cable rearward to move the lever into the spray position. The lever is independently moveable relative to the first and second cables such that movement of the lever caused by the first cable does not compress the second cable and movement of the lever caused by the second cable does not compress the first cable.

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 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 ground marking apparatus is configured to apply marking material to a ground surface. The ground marking apparatus includes a beam supported by a beam mount and extending along a beam axis. A carriage is disposed on the beam and movable on the beam along the beam axis. A carriage motor operably interfaces with the beam and is configured to move the carriage along the beam. A dispense arm is supported by the carriage and is configured to move relative to the beam as the carriage moves along the beam.

Abstract: A texture sprayer comprises an air compressor, a motor, a spray gun, an airflow switch, and a pressure switch. The air compressor is disposed to send the pressurized gas down a pneumatic line, and is driven by the motor. The spray gun receives pressurized gas from the pneumatic line, and expels the gas when actuated. The airflow and pressure switches are both disposed on the pneumatic line. The airflow switch is situated between the spray gun and the air reservoir, and powers the motor when gas flows through the airflow switch. The pressure switch powers the motor whenever pressure within the pneumatic line falls below a threshold value.
