Full‑visibility structural design enables unobstructed observation of piston movement and internal valve working states.\u003c\/li\u003e\n\u003cli\u003eFull assembly consists of cylinder, piston, steam chamber, steam‑flow reversing valve, crank‑connecting‑rod mechanism, cast‑iron flywheel, support bracket and base bottom plate.\u003c\/li\u003e\n\u003cli\u003eBuilt‑in steam‑pressure regulating structure. Supports two distinct operating modes: pneumatic drive and manual cranking. Adjust running speed freely while working under pneumatic‑power conditions.\u003c\/li\u003e\n\u003cli\u003eCast‑iron flywheel provides stable rotational inertia for smooth operation.
