The weight of the mine pump rod pulls up the piston in the cylinder, drawing in steam. Cold water is then sprayed into the cylinder causing the steam to condense. This creates a vacuum which pulls the piston down again. The self-acting valve gear regulates the inlet of cold water and steam. The jack pump in the well supplies the cold water for the system
