摘要：
Various embodiments concern a sprayer having a blower that outputs a HVLP flow of air into a hose, the hose connecting with a spray gun. A pressure sensor measures pressure of the HVLP air within the hose via a tube that branches from a fitting to which the hose connects. If the sensor indicates that the pressure level has increased above a threshold amount, indicating that the trigger of the spray gun is not being actuated, then power output to the blower is reduced (e.g., stopped). HVLP air is trapped within the hose by two valves when the trigger is not actuated. When the sensor indicates that the pressure level has decreased, corresponding to release of the trapped HVLP air into the gun for spraying by actuation of the trigger, power to the blower is increased (e.g., resumed).
