Abstract
One or more techniques and/or systems are disclosed for a foam fluid dispensing device that allows for quick and easy adjustment between a straight stream and dispersed stream. A user can quickly adjust between various stream patterns using a common motion in nozzle operation. An example device can comprise a nozzle comprising a nozzle body and an inlet configured to receive a flow of fluid, with a nozzle stem centrally disposed in the nozzle and fixedly engaged with the nozzle body. The device can also comprise a foam tube configured to receive and dispense at least a portion of the flow of fluid from the nozzle, with a foam tube coupler fixedly engaged with the foam tube. The foam tube coupler can be configured to operably couple with the nozzle stem.
Claims12
A device for dispensing firefighting fluid, comprising:
- a nozzle comprising a nozzle body, an inlet configured to receive a flow of fluid, and an outlet to dispense the fluid from the nozzle;
- a nozzle stem centrally disposed in the nozzle and fixedly engaged with the nozzle body;
- a foam tube attachment configured to receive and dispense at least a portion of the flow of fluid from the outlet of the nozzle the foam tube attachment comprising a foam tube coupler configured to selectably, operably couple the foam tube attachment with the nozzle stem, wherein an air gap is formed between the nozzle outlet and the foam tube attachment when the foam tube coupler is coupled with the nozzle stem;
- and
- a pattern sleeve operably coupled with the nozzle body and linearly translating between a first position and a second position, the first position comprising an extended position providing a substantially straight stream flow of fluid from the outlet of the nozzle to the foam tube attachment, wherein air is drawn into the foam tube attachment through the air gap, the second position comprising a retracted position that provides a dispersed flow of fluid from the nozzle outlet that passes through the air gap, substantially bypassing the foam tube attachment.
A system for dispensing firefighting fluid, comprising:
- a nozzle configured to dispense the fluid at an outlet end, comprising:
- a pattern sleeve configured to:
- direct the fluid in a substantially straight pattern at the outlet end, in a first position;
- and
- direct the fluid in a substantially dispersed pattern at the outlet end, in a second position, the dispersed pattern configured to allow the fluid to substantially bypass an inlet to a foam tube attachment;
- and
- the foam tube attachment comprising the inlet, an outlet, and a nozzle connector configured to operably couple the foam tube attachment with the nozzle, the nozzle connector providing an air gap between a nozzle outlet and the foam tube attachment inlet, the foam tube attachment configured to:
- receive the straight pattern of the fluid at the inlet;
- receive air at the inlet;
- and
- dispense a fluid/air mixture at the outlet;
- wherein the straight pattern of fluid passes from the nozzle outlet to the foam tube inlet and air is drawn into the foam tube through the air gap when the nozzle is disposed in the first position, and the dispersed pattern of fluid passes through the air gap and bypasses the foam tube attachment in the second position.
