About This

• Dual‑propulsion steam‑engine demonstrator regulated by steam‑reversing valve. Alternating steam intake from both cylinder ends drives piston reciprocating motion for thermodynamics principle demonstration.
• Transparent plastic cylinder and steam‑chamber construction. Full‑visibility structural design enables unobstructed observation of piston movement and internal valve working states.
• Full assembly consists of cylinder, piston, steam chamber, steam‑flow reversing valve, crank‑connecting‑rod mechanism, cast‑iron flywheel, support bracket and base bottom plate.
• Built‑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.
• Cast‑iron flywheel provides stable rotational inertia for smooth operation. External independent gas source is required to perform pneumatic‑driven experimental trials.
