Object Details
- Description
- The valve in this model of a typical mid-19th century engine cuts off the steam to the cylinder at a fixed point in the stroke, resulting in relatively poor efficiency. Speed could only be regulated by throttling the main steam supply. A single eccentric drove the steam valve. The valve was a simple, D-type slide valve. The valve casing and cylinder are sectioned to allow visualization of the mechanisms.
