N-gun ja ai-dty cylinder a bungli galaw ai tara gaw Pascal a tara hpe madung tawn ai. Hydraulic sau a n-gun gaw piston hpe shamu shamawt shangun nna, dai hku nna jak rung arung arai ni a linear reciprocacating motion hpe chye na hkra galaw ya ai. Shi a madung bungli galaw ai lam gaw lawu na hte maren rai nga ai:
- Hydraulic n-gun bang ai lam: Hka htung sau gaw sau hka htung hku nna cylinder a rodless chamber de shang wa ai shaloi, sau n-gun gaw piston ntsa kaw maren sha galaw ya ai. Hydraulic sau gaw n-gun n rawng ai majaw, n-gun gaw matut nna, piston hpe axial shamu shamawt lam hpe shapraw na matu, matut nna shalai nna, shadut na re.
- Piston shamu shamawt ai lam: Hydraulic sau n-gun a galaw ai lam npu hta, piston gaw piston rod hpe shi hte matut mahkai nna, n bung ai hku shamu shamawt na matu mawdaw gau ai. Rodless chamber gaw sau kata de shang wa ai shaloi, piston rod gaw shinggan de jat wa ai; rod chamber gaw sau kata de shang wa ai shaloi, piston rod gaw kata de bai nhtang wa ai.
- Mechanical energy output: Piston rod a linear motion hpe matut mahkai ai daw ni hku nna jak rung arung arai ni a thrust (sh) pulling force de galai shai kau ai, dai gaw lifting, push hte kaga galaw ai lam ni hpe chye na na matu re.
- Seal hte buffer: Seal gaw hka n-gun hpe pat shingdang ya nna, system a n-gun hpe ngang grin hkra galaw ya ai; dai buffer gaw, piston gaw stroke a jahtum de htawt nna, jak rung n-gun hpe shayawm ya ai shaloi, hkra machyi ai n-gun hpe hkam la lu ai.
