Abstract
A plural component sprayer receives individual flows of constituent materials and combines the constituent materials together to form a plural component material for application on a surface. A cartridge includes valving for controlling the flows of the constituent materials to a mix chamber within which the constituent materials combine to form the plural component material. The cartridge is mountable to and removable from a gun body of the plural component sprayer as a single unit.
Claims30
A cartridge for use with a plural component spray gun having a spray gun body and configured to receive first and second constituent materials that mix to form a plural component material, the cartridge comprising:
- a valving body extending between a first body end and a second body end;
- a first flow valve located within the valving body;
- a second flow valve located within the valving body;
- and
- a mix chamber cavity extending into the first body end of the valving body along a spray axis, the mix chamber cavity configured to receive at least a portion of a mix chamber of the plural component spray gun;
- wherein the cartridge is removable from the spray gun body as a single module;
- and
- wherein removal of the cartridge from the spray gun body necessarily disconnects the mix chamber from any connection with the spray gun body if the mix chamber has not already been removed from the cartridge.

A plural component spray gun configured to receive a first constituent material and a second constituent material and output a spray of a plural component material, the plural component spray gun comprising:
- a gun body;
- a handle projecting from the gun body;
- a trigger supported by the gun body;
- a cartridge removably mountable to the gun body, the cartridge comprising:
- a valving body extending between a first body end and a second body end, the second body end configured to interface with the gun body to connect the cartridge to the gun body;
- a first flow valve located within the valving body;
- a second flow valve located within the valving body;
- and
- a mix chamber cavity extending into the first body end of the valving body along a spray axis;
- wherein the cartridge is removable from the spray gun body as a single module;
- a mix chamber mountable within the mix chamber cavity;
- wherein removal of the cartridge from the gun body necessarily disconnects the mix chamber from any connection with the spray gun body if the mix chamber has not already been removed from the cartridge.

A cartridge for use with a plural component spray gun having an actuator assembly including a spray gun body and a displacer, the cartridge configured to receive first and second constituent materials that mix to form a plural component material, the cartridge comprising:
- a valving body extending between a first body end and a second body end along an axis;
- a mix chamber cavity formed in the valving body;
- a first flow valve located within the valving body;
- a second flow valve located within the valving body;
- a valve mount configured to interface with the actuator assembly at a dynamic interface to receive a mechanical input to actuate the first flow valve and the second flow valve between respective first states, in which flows of the first constituent material and the second constituent material to the mix chamber cavity are closed, and respective second states, in which the flows of the first constituent material and the second constituent material to the mix chamber cavity are open;
- and
- a body mount formed on the valving body and configured to interface with the actuator assembly at a static interface to mount the cartridge to the spray gun body;
- wherein the cartridge is mountable to and dismountable from the actuator assembly as a single unit.
