    摘要： A fire extinguisher discharge nozzle is provided and includes sidewalls and a biasing element. The sidewalls define an aperture through which a medium(s) is dischargeable and are adjustable between multiple first and multiple second positions associated with dilated and constricted conditions of the aperture, respectively. The biasing element is configured to bias the sidewalls toward assuming one of the multiple first or multiple second positions. The sidewalls are drivable toward assuming the other one of the multiple first or multiple second positions in opposition to bias applied by the biasing element in accordance with a characteristic of the medium(s).

    摘要： A fluid dispensing apparatus includes a dispenser body, a valve stem with a valve tip, and a nozzle having a nozzle body defining a fluid chamber terminating in a discharge outlet, an annular valve seat, and a resilient annular portion. A method for dispensing droplets of fluid with the fluid dispensing apparatus includes moving the valve stem relative to the dispenser body and the nozzle body, collecting fluid in the fluid chamber flowing from the dispenser body when the valve stem is moved in an upstream direction with the valve tip out of engagement with the annular valve seat and the resilient annular portion, and dispensing fluid in the fluid chamber out of the discharge outlet when the valve stem is moved in a downstream direction.

    摘要： Embodiments of a spray gun incorporating a needle for applying multiple component materials are provided. In accordance with certain embodiments, the spray gun includes a fluid delivery tip assembly comprising an inner passage, a hollow needle disposed within the inner passage of the fluid delivery tip assembly, wherein the hollow needle comprises at least two indentions along an outer circumferential surface of the hollow needle near an end of the hollow needle, a first passage configured to deliver a first spray fluid to a fluid tip exit of the fluid delivery tip assembly, wherein the first passage is defined by a volume between the fluid delivery tip assembly and the hollow needle, and a second passage through the hollow needle, wherein the second passage is configured to deliver a second spray fluid to the fluid tip exit of the fluid delivery tip assembly.

    摘要： A nozzle for a fluid dispenser configured to dispense fluid includes a nozzle body and a valve stem that has a valve tip and is movable in an upstream direction and a downstream direction. The nozzle also includes an annular valve seat that is configured to contact the valve tip when the valve stem moves in the downstream direction, and a resilient annular portion that extends from the nozzle body and is adjacent to the annular valve seat. As the valve stem moves in the downstream direction, the resilient annular portion contacts the valve tip, flexes radially outwards, and thereby forms a sealing engagement with the valve tip, to avoid undesirable additional dispensed volumes that may be caused if the valve tip recoils away from the valve seat following initial contact of these elements.
