What is pneumatic area in a landing gear strut?

What is pneumatic area in a landing gear strut?

What is pneumatic area in a landing gear strut?

(OP)
I'm confused by the definition of Pneumatic Area inside a landing gear (LG) strut/shock absorber. One article said it's the section area of OD of an inner cylinder. However, I thought it's the section area of ID of an outer cylinder. If the OD of the inner cylinder and the ID of the outer cylinder are different, it can make a big difference on the Pneumatic Area. Does anybody know the exact definition of the Pneumatic Area in LG industry?

Thanks

RE: What is pneumatic area in a landing gear strut?

But maybe thay can't be different by more than the clearance and seal requirements, in which case, they probably differ by less than 5%.
