New York Pump Governor, Steam Valve Open vents the pressure from accumulating under the steampiston. If this pressure were not allowed to escape,the air pressure on top would not be able to force the 588 LOCOMOTIVE ENGINEERING steam valve to its seat and shut off the pump, whereas,when steam is operating against the steam valve alone,it requires only about one third as much air pressure -3^
