Bump Valve Engine Design
Three points in the steam cycle are shown.
Design Updates:
- 5/2/11 - Rev. 2: Initial bump valve design.
- 5/6/11 - Rev. 3: Added flange on crankshaft end of cylinder and exhaust plenum.
- 5/10/11 - Rev. 4: Improved bump valve added, cylinder liner is now thick.
- 5/11/11 - Rev. 5: Added mount brackets, pillow block, extended piston stem.
- 5/25/11 - Rev. 6: Widened cylinder flanges, dropped water vent, added sensor vent, cylinder liner to scale.
- 7/20/11 - Rev. 7: Merged valve cover and mounting bracket. Added oiler.

Description
This is a single-action uniflow steam engine that uses a bump valve to admit steam and an exhaust vent to emit cooled steam.
Design Features:
- Simple design with a mix of fabricated and off-the-shelf parts.
- Modular and stackable - cylinders can be ganged together to increase power.
- Easy assembly - minimal welding
- Repairable - comes apart for cleaning, maintenance, and repair.
- Easy fabrication - lathing, milling, cutting, and drilling.
- Self-lubricating - oil sprays.
- Crank shaft can be configured for multiple cylinders.
Sub-assembly Designs:

- Steam Engine Design/Cylinder
- Steam Engine Design/Crank Shaft
- Steam Engine Design/Piston
- Steam Engine Design/Lubrication
- Steam Engine Design/Exhaust
