Ny karazana piston mifehy tena miasa izay afaka manitsy ny fanerena ho toy ny sanda napetraka miaraka amin'ny heriny manokana ary tsy misy angovo ivelany. ary tsy misy fitaovana pneumatika azo ampiasaina, fanampiny, piston type auto-operateur regulator dia afaka mitahiry angovo ho an'ny mpampiasa farany, ary ny tsindry dia azo amboarina ao anatin'ny elanelana napetraka.
Ny karazana piston mifehy tena miasa dia manana ireto karazana manaraka ireto araka ny fepetra fiasana samihafa:
ZZYP (karazana seza tokana), ZZYM (karazana akanjo) ary ZZYN (karazana seza roa), ary ny fehezam-boninkazo PPiston ihany koa dia manana fonony telo samihafa toy ny mahazatra, ny hatoka lava ary ny karazana mangatsiaka.Ho an'ny fampiharana samihafa, ity karazana PPiston ity dia mpitaingina piston, ary ny valva fanaraha-maso ny tenany dia manana karazana actuators telo samy hafa: film / piston / bellows.
Ny karazana piston mifehy tena miasa dia manana tombony hafa toy ny marani-tsaina sy marina mifehy, maka toerana kely sy asa tsotra ary be mpampiasa amin'ny fanaraha-maso ny tsindry amin'ny entona, etona na rano amin'ny solika, simika, herinaratra, metallurgy, sakafo, lamba, milina, indostrian'ny fanorenana sivily.
Ny karazana piston mifehy tena miasa dia natao sy namboarina araka ny fenitra AMSE / API / BS / DIN / GB
