Gas (pneumatic) shocks

[FRC66]

Under <R106> , Gas shocks are permitted on the robot
Under <R46> , Hydraulic Fluids or Components are not permitted on the robot
Since Gas (pneumatic) shocks contain hydraulic fluid, are they permitted under the current rules?

[FRC877]

May we use a gas operated shock similar to the ones used in rear left gates or the back window of an SUV?

This question is in relation to rule 8-46, specifically the part that prohibits "Hydraulic fluids or hydraulic components" from use in the robot. We have purchased a damper from http://www.guden.com. This is the page for the type of damper we bought: http://www.guden.com/display-GSD.asp...uery=GDE60%20E. We are hesitan to commit these viscuos dampers to use in our robot because of the risk of not being allowed to use them at the competition if they are deemed "hydraulic."

Thank you for your help.

Gas shocks (compressible gas springs) are permitted under Rule <R46>. Models of the shocks that contain small amounts of hydraulic fluid that is used as a lubricant, and which are completely sealed to prevent any escape of the fluid (and therefore not violate Rule <R36>), are acceptable. Hydraulic springs which utilize hydraulic fluid as the major damping fluid, and are therefore not really "pneumatic shocks," are not permitted.
