    • The invention relates to a lubricating device (5) comprising a bypass valve (9) having an inlet (IN) connected to a supply circuit (7), a first outlet (M) capable of being connected to elements to be lubricated, and a second outlet (BP) connected to a bypass circuit (8). The bypass valve (9) comprises a valve (14) housed in a cavity (15) of the bypass valve (9), dividing the cavity (15) into a first chamber (16) and a second chamber (17). The first chamber (16) is connected to the inlet (IN), and the valve (14) is capable of sliding between a first position and a second position in accordance with difference ?? in pressure between the two chambers (16, 17), wherein an actuator (26) returns the valve (14) toward the first position thereof. In the first position, a fluid passage from the first chamber (16) to the second outlet (BP) is open, and a fluid passage from the first chamber (16) to the first outlet (N) is closed. In the second position, the fluid passage from the first chamber (16) to the first outlet (N) is open, and the fluid passage from the first chamber (16) to the second outlet (BP) is closed. At least in the second position, the valve (14) substantially sealingly separates said first and second chambers (16, 17), while the second chamber (17) remains in fluid communication with the second outlet (BP).

    • A dual function rapid shutdown and ecology system for fuel delivery systems for engines, specially aircraft gas turbine engines, is disclosed. The dual function is accomplished in a single module operated by a single electromagnetic solenoid valve commanded by the engine electronic control unit. Upon actuation of the solenoid valve, a large spring loaded piston strokes to the extreme of its travel creating a cavity having a volume sufficient to accommodate all fuel leftover in the fuel manifold and distribution system at shutdown, thus preventing atmospheric pollution or engine damage upon subsequent operation. Simultaneous with actuation of the solenoid valve, fuel pressure differentials cause a small piston to stroke to the extreme of its travel opening fuel passageways and causing all the fuel being delivered to the engine combustion chamber to bypassed back to pump inlet, thus effectively accomplishing the rapid shutdown function. An alternate embodiment allows for use of the dual function system on engines employing low pressure differentials along the various stages of the fuel control system manifold or where the ecology function is not required.
    • 公开了一种用于发动机,特别是飞机燃气涡轮发动机的燃料输送系统的双功能快速关闭和生态系统。 双重功能是在由发动机电子控制单元指令的单个电磁阀操作的单个模块中实现的。 在致动电磁阀时,大的弹簧加载的活塞冲击到其行程的最后,产生一个空腔,该空腔具有足以在关闭时容纳燃料歧管和分配系统中的所有燃料剩余量,从而防止随后的大气污染或发动机损坏 操作。 与电磁阀的致动同时,燃料压力差导致小活塞行进到其行进开启燃料通道的极端,并且使得所有被输送到发动机燃烧室的燃料绕过回到泵入口,从而有效地实现快速 关机功能。 替代实施例允许在燃料控制系统歧管的各个阶段使用低压差的发动机上使用双功能系统,或者不需要生态功能。
