Abstract
The present invention relates to a paintgun with pneumatic feeding and discharging process which mainly includes a pneumatic delivery mechanism. The pneumatic delivery mechanism consists of a flow-guiding body, a flow-guiding piston and a delivery tube. The flow-guiding body consists of a major air channel at the front end and a flow-guiding chamber at the rear end thereof. The flow-guiding chamber contains an input port at one side thereof which is in connection with an air pressure source and an output port at the other side thereof which communicates with a minor air channel at the wider part of the flow-guiding body. A stopper is used to control the opening and closing of the air flow channel. The flow-guiding piston is disposed within the flow-guiding chamber. The flow-guiding chamber is divided by the valve body into a front and a rear air pressure chambers with different pressure area.
