The cavity within the strut and piston is filled with gas (usually nitrogen, sometimes air—especially on <a href="/wiki/Light_aircraft" title="Light aircraft">light aircraft</a>) and <a href="/wiki/Oil" title="Oil">oil</a> (usually hydraulic fluid), and is divided into two chambers that are connected by a small orifice of a precise, calculated size.<sup id="cite_ref-olson_how2019_4-2" class="reference"><a href="#cite_note-olson_how2019-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-23" class="reference"><a href="#cite_note-23"><span class="cite-bracket">[</span>23<span class="cite-bracket">]</span></a></sup> </p><p>When the aircraft is stationary on the ground, its weight is supported by the compressed gas in the cylinder.<sup id="cite_ref-vansickle_1-1" class="reference"><a href="#cite_note-vansickle-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> During landing, or when the aircraft taxis over bumps, the piston slides up and down.<sup id="cite_ref-olson_how2019_4-3" class="reference"><a href="#cite_note-olson_how2019-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> This movement compresses the gas, which acts as a spring, and forces oil through the orifice, which acts as a damper. A tapered rod is used on some designs to change the size of the orifice as the piston moves, providing greater resistance as compression of the strut increases. Additionally, a check valve is sometimes used to uncover additional orifices so that damping during compression is less than during rebound. Oleo struts absorb and dissipate forces by converting a portion of the accumulated kinetic energy into thermal energy.<sup id="cite_ref-olson_how2019_4-4" class="reference"><a href="#cite_note-olson_how2019-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> </p><p><a href="/wiki/Pneumatics" title="Pneumatics">Pneumatic</a> systems like the oleo strut generally have long operating lives, and the construction is not unusually complex for maintenance purposes.<sup id="cite_ref-24" class="reference"><a href="#cite_note-24"><span class="cite-bracket">[</span>24<span class="cite-bracket">]</span></a></sup> Nitrogen is usually used as the gas instead of air, since it is less likely to cause <a href="/wiki/Corrosion" title="Corrosion">corrosion</a>.
