Abstract
The invention relates to an injection device (10) configured to atomize a liquid into droplets using a gas, comprising a hollow tubular body (12) of longitudinal direction (X). An internal wall (13) defines a first zone referred to as a contact zone (Z1) and a second zone (Z2). The device (10) is notably provided with an atomizing element (18) mounted on an opening (19) of the body situated facing an opening (17) for injecting a liquid, comprising a tubular pipe (20) for conveying gas into the first zone (Z1), and a target (21) situated at the centre of the pipe. The body has an internal cross-section that varies continuously or is constant over its entire length (for example the shape of a simple cylinder) and of which the internal wall is provided, between the zones (Z1) (Z2), with at least one chicane (26i, 26′i) projecting from the internal wall towards the inside of the body.
