ABSTRACT:
The water box and expansion chamber for the radiator of an internal combustion engine radiator may be moulded as a single piece. The water box (12) and the expansion chamber (11) are connected in the usual way near the top by a degassing duct. Near the bottom it is important to provide suction in the expansion chamber to ensure effective degassing. Suction may either be provided by a channel (21) enabling the main outlet flow of fluid from the radiator to entrain fluid from the expansion chamber, or it may be provided by a separate suction outlet (30) for connection to a pump. Different kinds of engine use different suction systems. The present invention allows both systems to be catered for by a single type of device in which the unwanted suction path is readily closed off, either during the original moulding operation (e.g. wall 31) or by means of a stopper (20) that provides a path when inserted in out orientation, but which closes a path when turned to another orientation.
