Abstract
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.
Claims20
An injection jet for a fluid system having a first fluid reservoir and a second fluid reservoir, the injection jet comprising:
- a body;
- a first passage disposed within the body and in fluid communication with the first reservoir;
- a second passage disposed within the body and in fluid communication with the second fluid reservoir;
- wherein the first passage and the second passage channel a fluid through the body;
- and
- wherein the fluid channeled through the first passage remains fluidly separated from the fluid channeled through the second passage while the fluid is channeled through the body such that fluid from the first reservoir remains separated from the second reservoir while channeled through the body.
An injection jet for an aircraft component, the injecting jet comprising:
- a body having:
- a first port;
- a second port;
- a third port;
- and
- a fourth port;
- wherein the first port and the second port allow a fluid to enter into the body;
- wherein the third port and the fourth port allow the fluid to exit the body and enter into the aircraft component;
- wherein the first port is in fluid communication with the third port;
- wherein the second port is in fluid communication with the fourth port;
- and
- wherein the body is configured such that the fluid passing through the first port remains fluidly separated from and coaxial to the fluid passing through the second port while the fluid is channeled through at least a portion of the body.
A system for supplying a fluid to a working element, the system comprising:
- a main reservoir in fluid communication with the working element;
- an emergency reservoir in fluid communication with the working element;
- and
- an injection jet in fluid communication with both the main reservoir and the emergency reservoir, the injection jet comprising:
- a body;
- a first passage disposed within the body and in fluid communication with the main reservoir, the first passage for channeling the fluid from the main reservoir through the body;
- and
- a second passage disposed within the body and in fluid communication with the emergency reservoir, the second passage for channeling the fluid from the emergency reservoir through the body;
- wherein the fluid channeled through the first passage remains fluidly separated from the fluid channeled through the second passage while the fluid is channeled through the body such that fluid from the main reservoir remains fluidly separated from the emergency reservoir while channeled through the body;
- wherein the system operates in a standard mode and in an emergency mode;
- wherein both the first passage and the second passage supply the fluid to the working element during standard mode;
- and
- wherein the second passage supplies the fluid to the working element during emergency mode.
