Abstract
A water jet unit for ships, comprises a propeller pump having a pump housing connected on its inlet side with an inlet channel and on its outlet side with a water-jet directing outlet means. The pump housing has a hub housing which is arranged centrally in the flow path of the water through the pump housing and which is carried by guide vanes extending radially between the wall of the pump housing and the hub housing. The impeller is mounted on the end of a pump shaft extending into the pump housing through the inlet channel and is journalled in the hub housing by means of an axial bearing and a radial bearing. Both bearings are spherical and have a substantially common center.
