Ericsson engine

Ericsson motor for pumping water

The Ericsson engine is an external combustion engine developed by John Ericsson , a hot air engine similar to the Stirling engine . The thermodynamic cycle of the Ericsson engine is the Ericsson cycle .

The Ericsson motor was used to drive pumps in the 19th and early 20th centuries . Manufacturers were DeLameter Iron Works and the Rider-Ericsson Engine Company .

A modern application for Ericsson motors is regenerative energy generation, where the motor can be heated using both solar heat and biomass.

functionality

The heat supply to the gas below the piston is converted into mechanical work as the piston moves upwards. Air is pushed out at the top and sent through the regenerator via the pressure tank on the left and the valve on the bottom left. When the piston lowers again, this air is pressed out at constant pressure with heat dissipation in the regenerator through the then switching valve at the bottom left. Cold air is sucked in above the piston.
