Spray apparatus operable by pressurized air

A paint spray gun operable by pressurized air is provided. The paint spray gun includes a container for holding paint and pressurized air and a paint spray head for receiving paint from the container and mixing the paint with a continuous flow of pressurized air to produce a paint spray. First and second fluid paths are provided between the container and the spray head to allow paint and air, respectively, to flow from the container to the paint spray head. In a preferred embodiment, a manually operable valve is provided in the first fluid path for controlling the flow of paint from the container to the paint spray head. The paint spray head is mounted on a displaceable actuator of the valve and a manually operable trigger mechanism is provided for engaging and moving the paint spray head to displace the actuator to open the valve to permit paint to flow to the paint spray head.
