What do you call a shock strut on an aircraft?
It is sometimes referred to as an air/oil or oleo strut. A shock strut is constructed of two telescoping cylinders or tubes that are closed on the external ends. The upper cylinder is fixed to the aircraft and does not move. The lower cylinder is called the piston and is free to slide in and out of the upper cylinder.
Where is the instruction plate on a shock strut?
Shock struts contain an instruction plate that gives directions for filling the strut with fluid and for inflating the strut. The instruction plate is usually attached near filler inlet and air valve assembly. It specifies the correct type of hydraulic fluid to use in the strut and the pressure to which the strut should be inflated.
How is the pressure of a shock strut controlled?
It is automatically controlled by the taper of the metering pin in the orifice. When a narrow portion of the pin is in the orifice, more fluid can pass to the upper chamber. As the diameter of the portion of the metering pin in the orifice increases, less fluid passes.
How much psi does a strut servicing valve have?
Two common types of high pressure strut servicing valves are illustrated in Figure 9. The AN6287-1 valve in Figure 9-A has a valve core assembly and is rated to 3,000 pounds per square inch (psi). However, the core itself is only rated to 2,000 psi.

What are shock boots and strut bellows for?
Shock boots protect the piston rod from road debris, dirt, and contaminants to prolong the life of shocks. Strut bellows are a rubber boot designed to protect the strut shaft through its full range of motion, which prevents premature failure and damage to seals and corrosion on the strut shaft.
