Patent attributes
The invention relates to a fuel metering and distribution unit (10) which comprises in particular a slide valve (20) and a set of slots (41) configured with geometries, dimensions and positions such that:in a first range of displacement of the slide valve, the flow area (31) which feeds the outlet port of the start-up ramp is progressively opened with the displacement of the slide valve (20), while the area (41) of the set of slots which feeds the outlet port of the main ramp is closed,then, in a second range of displacement of the slide valve (20), the area (41) of the set of slots which feeds the outlet port (42) of the main ramp is progressively opened with the displacement of the slide valve,while the flow area (31) which feeds the outlet port of the start-up ramp is kept open, the outlet port (42) of the main ramp thus being able to receive a portion of the total metered flow rate at the flow area (31) feeding the outlet port of the start-up ramp.
