M37 - Stirling -water pump
|Year of acquisition||2008|
|Power piston||stroke||20 mm|
|Idle speed||1 Hub /s|
Yet another model I bought, a glassblower's piece of art: All components, including the valve balls, are made of glass.
On one side of the U-shaped tube, the water column acts as displacer piston, on the other as power piston. The pressure fluctuations operate the attached pump, which continuosly circulates water from a container and back.
