Transparent design: Certain components are made with transparency, allowing for comprehensive observation of the working details without any blind spots. Dual-propulsion steam engine: This model features a dual-propulsion system, where steam is managed by adjusting the valve, enabling alternating intake air to drive the piston. Comprehensive construction: The apparatus includes a cylinder, piston, steam chamber, steam flow reversing valve, crank connecting rod mechanism, flywheel, bracket, and base. Enhanced visibility: The cylinder and steam chamber are constructed from clear plastic for easy observation of the moving piston and steam flow reversing valve. Adjustable steam system: A steam passage connects the cylinder to the steam chamber, which includes a steam pressure regulator to control the machine's speed, while the flywheel is made of cast iron.
