Lance, in particular extinguishing lance for fighting fires

A lance for dispensing a pressurized fluid or a mixture of the pressurized fluid and an additive, the lance comprising:

• a lance body,
• a handle arrangement, which handle arrangement is arranged or formed on the lance body and comprises a first handle and a second handle, wherein the first handle and the second handle are arranged at a distance from one another in a direction along a longitudinal extension of the lance body, and wherein each of the first handle and the second handle can each be grasped separately by one hand of a user for operating the lance,
• a with a first channel inlet and a first channel outlet, wherein the first channel inlet is connectable to a feed line of the pressurized fluid,
• a first actuating means arrangement, which first actuating means arrangement is arranged in a surrounding area of the first handle of the handle arrangement, and comprises a first actuating means that is in direct operative connection to the first channel, wherein the first actuating means is adjustable from a locked position to a flow position and vice versa in order to adjust a flow of the pressurized fluid through the first channel,
• a first container with a removal opening, wherein the first container is configured to accommodate the additive,
• a second channel with a second channel inlet and a second channel outlet, wherein the second channel inlet is flow-connected to the removal opening of the first container,
• a second actuating means arrangement, which second actuating means arrangement comprises a second actuating means, wherein the second actuating means is adjustable from a closed position into a release position and vice versa in order to adjust a flow of the first additive through the second channel,
• a nozzle arrangement with a first nozzle body, wherein a first inlet opening, a second inlet opening, an outlet opening (23), and a mixing chamber are formed or arranged in the first nozzle body, and wherein the first inlet opening and the second inlet opening open into the mixing chamber, and the mixing chamber is flow-connected to the outlet opening,
• wherein the first channel outlet of the first channel is flow-connected to the first inlet opening of the first nozzle body,
• wherein the second channel outlet of the second channel is flow-connected to the second inlet opening of the first nozzle body,
• wherein the second actuating means arrangement comprises a control pin, which control pin is mounted on the lance body so as to be pivotable about a longitudinal axis of the control pin, and the second handle of the handle arrangement is rotationally coupled to the control pin of the second actuating means arrangement and the second handle and the control pin are jointly pivotable about the longitudinal axis of the control pin,
• wherein the second actuating means of the second actuating means arrangement is arranged in the control pin,
• wherein a third channel with a third channel inlet and a third channel outlet is provided, and the third channel inlet is flow-connected to an outer environment,
• wherein the first channel and the third channel are arranged or formed in the lance body,
• wherein the third channel outlet of the third channel is directly flow-connected to the first inlet opening of the first nozzle body,
• wherein the second actuating means of the second actuating means arrangement is in direct operative connection to the third channel, and the second actuating means arrangement is arranged in a surrounding area of the second handle,
• wherein the third channel is continuously opened between the third channel inlet and its the third channel outlet when the second actuating means is in the release position, and thus, a flow of air from the environment through the third channel to the mixing chamber enabled,
• wherein in an operating mode, the third channel is closed between the third channel inlet and the third channel outlet when the second actuating means is in the closed position, and thus, a flow of air from the environment through the third channel to the mixing chamber is prevented, and in the operating mode, the first additive is drawable into the mixing chamber from the first container via the second channel,
• wherein the first channel comprises a first partial channel and a second partial channel in a longitudinal section of the first channel between the second actuating means arrangement and the first channel outlet, and
• wherein the first partial channel is arranged inside the second partial channel.
