An injection jet includes a body having a first and a second passage disposed therein for channeling a fluid to a working element. The first passage remains fluidly separated from the second passage. A system includes the injection jet along with a main reservoir and an emergency reservoir. The first passage is in fluid communication with the main reservoir, while the second passage is in fluid communication with the emergency reservoir. The system operates in a standard mode and an emergency mode. Both the first passage and the second passage are configured for jointly supplying fluid to the working element during standard mode. The second passage is configured for independently supplying fluid to the working element during emergency mode.
