Abstract
An aircraft hydraulic system for operating a plurality of hydraulically-operated actuators in the aircraft having a hydraulic reservoir in which hydraulic fluid is stored, a hydraulic distribution system coupling the hydraulic reservoir to the actuators and having a main flow line coupled to the hydraulic reservoir, a hydraulic pump fluidly coupled to the main flow line and the hydraulic reservoir to pump hydraulic fluid from the reservoir to the main flow line, a main filtration system fluidly coupled to the main flow line upstream of at least some of the actuators, and a self-cleaning filter fluidly coupled upstream of the main filtration system.
Claims13
An aircraft hydraulic system for operating a plurality of hydraulically-operated actuators in the aircraft, comprising:
- a hydraulic reservoir in which hydraulic fluid is stored;
- a hydraulic distribution system coupling the hydraulic reservoir to the actuators and having a main flow line coupled to the hydraulic reservoir;
- a hydraulic pump fluidly coupled to the main flow line and the hydraulic reservoir to pump hydraulic fluid from the hydraulic reservoir to the main flow line;
- a main filtration system fluidly coupled to the main flow line upstream of at least some of the actuators;
- and
- a self-cleaning filter fluidly coupled upstream of the main filtration system and having a body with a main flow portion, coupled in-line to the main flow line, and a branch portion, with a branch filter located within the body to filter hydraulic fluid passing through the branch portion and oriented relative to the main flow portion such that hydraulic fluid flowing through the main flow portion cleans the branch filter.
