用于飞行器发动机的多点喷射装置
Abstract:
本发明涉及一种用于飞行器发动机(M)的多点燃料喷射装置(1)，该多点燃料喷射装置包括：输入管线(10)、至少两条喷射管线(11，12)以及净化管线(14)、燃料分配器部件(2)，该燃料分配器部件被连接至每条管线并包括具有喷射通道(223)的可动元件(22)，其中，可动元件(22)还包括净化通道(226)并被配置成呈现第一位置范围和第二位置范围，在第一位置范围，喷射通道(223)将输入管线(10)与喷射管线(11，12)互连，在第二位置范围，喷射通道(223)将输入管线(10)与至少第一喷射管线(11)互连，并且同时，净化通道(226)将净化管线(14)与至少第二喷射管线(12)互连，该装置的特征在于它还包括致动器，该致动器适于在检测到分配部件的故障时将可动元件移动至安全位置，在可动元件(22)的这种安全位置，喷射通道(223)将输入管线(10)与第一喷射管线(11)互连，并且同时，净化通道(226)不将净化管线(14)与任何喷射管线(12)互连。
Abstract(English):

The invention relates to a multi-point fuel injection device (1) for an aircraft engine (M), comprising an inlet line (10), at least two injection lines (11, 12), and a purge line (14), a fuel distributor member (2) connected to each line and comprising a moveable element (22) which comprises an injection passage (223), in which the moveable element (22) additionally comprises a purge passage (226), and is configured to adopt a first range of positions in which the injection passage (223) interconnects the inlet line (10) and the injection lines (11, 12), and a second range of positions in which the injection passage (223) interconnects the inlet line (10) and at least a first injection line (11) while the purge passage (226) interconnects the purge line (14) and at least a second injection line (12), the device being characterized in that it additionally comprises 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 (22), the inlet line (10) and the first injection line (11) while the purge passage (226) does not interconnect the purge line (14) to any of the injection lines (12).
