Abstract
A spray gun for a plural component system is provided. The spray gun includes a first component delivery line and a second component delivery line. The spray gun also includes a nozzle, configured to receive and mix a first component received from the first component delivery line with a second component received from the second component delivery line. The spray gun also includes an air purge system configured to, when the spray gun is in a non-actuated position, purge the nozzle of the first and second components and, when the spray gun is in an actuated position, aid in atomization of the mixture of the first and second components.
Claims14
A plural component applicator comprising:
- a first component inlet configured to receive a first component from a first delivery line;
- a second component inlet configured to receive a second component from a second delivery line;
- a nozzle comprising:
- a first component nozzle inlet;
- a second component nozzle inlet;
- and
- a nozzle outlet configured to expel a mixture of the first component and the second component;
- and
- a valve having:
- an opened position configured to:
- allow flow of the first component to the first component nozzle inlet,
- allow flow of the second component to the second component nozzle inlet, and
- restrict an air flow to the first component nozzle inlet;
- and
- a closed position configured to:
- restrict flow of the first component to the nozzle,
- restrict flow of the second component to the nozzle, and
- allow at least a portion of the air flow to the first component nozzle inlet in a downstream direction that is towards the nozzle outlet, and
- a trigger configured to rotate the valve between the opened position and the closed position.
A plural component applicator comprising:
- a first component inlet configured to receive a first component from a first delivery line;
- a second component inlet configured to receive a second component from a second delivery line;
- a nozzle comprising:
- a first component nozzle inlet;
- a second component nozzle inlet;
- and
- a nozzle outlet configured to expel a mixture of the first component and the second component;
- a valve comprising:
- a first component channel;
- a second component channel;
- an air channel;
- an opened position configured to:
- place the first component channel in fluidic communication with the first component nozzle inlet to allow flow of the first component to the first component nozzle inlet through the first component channel;
- place the second component channel in fluidic communication with the second component nozzle inlet to allow flow of the second component to the second component nozzle inlet through the second component channel;
- and
- align the air channel with a first plug to restrict an air flow to the first component nozzle inlet;
- and
- a closed position configured to:
- align the first component channel with a second plug to restrict flow of the first component to the first component nozzle inlet;
- align the second component channel with a third plug to restrict flow of the second component to the second component nozzle inlet;
- and
- place the air channel in fluidic communication with both the first component nozzle inlet to allow at least a portion of the air flow to the first component nozzle inlet in a downstream direction that is towards the nozzle outlet and the second component nozzle inlet to allow at least a second portion of the air flow to the second component nozzle inlet in a downstream direction that is towards the nozzle outlet;
- and
- a trigger configured to rotate the valve between the opened position and the closed position.
