REGULATORY AND CLOSURE OF OLIEBRAENDERES AIR INTAKE SAAB TEST IN HEAT BOILERS

摘要

Apparatus for controlling air intake through the air intake aperture of the oil burner in a heating boiler includes a rotary coupling member adapted to be connected to the shaft of the oil pump and/or air blower so that it extends substantially along the axis of the intake aperture, a first sleeve member detachably mounted on the coupling member, a second sleeve member slidably mounted on the first sleeve member and to which a closure member is affixed for axial movement away from and towards to open and close, respectively, the intake aperture. At least one spring member is provided whose ends are connected to respective ones of the first and second sleeve members thereby interconnecting the same. A weight is fixed to the body of the spring member so that upon starting the boiler causing the pump and/or blower shafts to rotate, the closure member moves axially away from the air intake aperture to open the same under the centrifugal force acting on the weight member while upon stopping the boiler with the consequent stopping of the pump and/or blower shafts, the closure member moves axially towards the air intake aperture to close the same under the force of the spring member.
