Abstract
In a pump comprising a slotted tube motor, the ventilating procedure is carried out by the water entering a rotor chamber and being caused to circulate by means of the rotating rotor in such a manner that a circulating ring of liquid is formed within the rotor chamber, and that the air present in the chamber is pressed towards the axis of rotation of the rotor. The liquid flows from a pump room into the rotor chamber through a bearing slot in a front sliding bearing situated at the impeller of the pump. Liquid from the ring of liquid adjacent the rear sliding bearing is carried into a bearing slot in the rear sliding bearing by way of a connecting duct formed in part in the bearing sleeve. This sliding bearing opposes an air duct closed by a vent plug. The rotor chamber and the air duct are interconnected solely through the bearing slot in the rear sliding bearing.
