发明名称 MULTI-POINT INJECTION DEVICE FOR AN AIRCRAFT ENGINE
摘要 A multi-point fuel injection device for an aircraft engine, including an inlet line, at least two injection lines, and a purge line, a fuel distributor member connected to each line and including a moveable element which includes an injection passage, in which the moveable element additionally includes a purge passage, and is configured to adopt a first range of positions in which the injection passage interconnects the inlet line and the injection lines, and a second range of positions in which the injection passage interconnects the inlet line and at least a first injection line while the purge passage interconnects the purge line and at least a second injection line, the device being additionally includes an actuator adapted to move the moveable element into a safety position when a failure of the distribution member is detected, the injection passage (223) interconnecting, in this safety position of the moveable element, the inlet line and the first injection line while the purge passage does not interconnect the purge line to any of the injection lines.

主权项 1. A multi-point fuel injection device for an aircraft engine, comprising: an intake line, at least two injection lines and a purge line, a fuel distributor connected to each line and comprising a movable element which includes an injection passage, wherein the movable element further includes a purge passage and is configured to assume: a first range of positions wherein the injection passage interconnects the intake line and the injection lines, and a second range of positions wherein the injection passage interconnects the intake line and at least one first of the two injection lines while the purge passage interconnects the purge line and at least a second of the two injection lines, an actuator configured to move the movable element into a safety position upon detecting a failure of the fuel distributor, the injection passage (223) interconnecting, in said safety position of the movable element (22), the intake line (4-0) and at least one (11) of the two injection lines while the purge passage does not interconnect the purge line (44) with any of the two injection lines (12).
