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.
Claims20
A nozzle for a plural component applicator comprising:
- a first component inlet configured to receive a flow of a first component;
- a second component inlet configured to receive a flow of a second component;
- an outlet;
- and
- a maze disposed between the outlet, the first component inlet and the second component inlet, the maze being configured to receive and mix the first component and the second component by directing flow of the first component and the second component in a first direction then directing flow of the first component and the second component in a second direction that is opposite the first direction, before the first component and the second component are expelled through the outlet.
A nozzle for a plural component applicator comprising:
- a first component nozzle inlet configured to receive a first component;
- a second component nozzle inlet configured to receive a second component;
- a nozzle outlet configured to expel a mixture of the first component and the second component;
- and
- a mixing structure configured to:
- receive the first component from the first component nozzle inlet and the second component from the second component nozzle inlet;
- guide the first component and the second component along a component pathway formed by the mixing structure;
- and
- cause rotation of the first component and the second component in a first direction of rotation and in a second direction of rotation, to generate the mixture of the first component and the second component.
A nozzle for a plural component applicator comprising:
- a nozzle body;
- a first component nozzle inlet configured to receive a first component;
- a second component nozzle inlet configured to receive a second component;
- a nozzle outlet configured to expel a mixture of the first component and the second component;
- and
- a mixing structure, disposed upstream from the nozzle outlet, that forms a component pathway and that is configured to:
- receive the first component from the first component nozzle inlet and the second component from the second component nozzle inlet;
- and
- cause rotation of the first component and the second component in a first direction of rotation and in a second direction of rotation along the component pathway to generate the mixture of the first component and the second component.
