<p>This invention concerns a barycentric support for balancing the motor-rotor unit on airtight combustion chamber boilers employed in heating systems. The device in question consists of a rubber collar which, thanks to an adjusting screw, can be pushed with the force required, either against the bottom wall of the stator unit or against a special bracket, projecting from the front support U-bolt of the motor-rotor unit; the balancing thrust of the collar is applied in a vertical direction which passes through the barycentre of the motor-rotor unit. <IMAGE></p> |
