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.
