<p>A jet pump comprises a HP inlet vent, a nozzle connected to the HP inlet vent via a HP fluid conduit and configured to discharge a first fluid flowing through the HP inlet into a nozzle discharge zone, a LP inlet vent, a LP fluid conduit connected to the LP inlet vent and configured to discharge a second fluid flowing through the LP inlet vent into the nozzle discharge zone. A mixing tube is provided downstream of the nozzle discharge zone for mixing the first and second fluids and an outlet vent is located downstream of the mixing tube for discharging a mixture of the first and second fluids from the jet pump. The jet pump includes a spinner mechanism upstream of the nozzle discharge zone for causing spinning rotation of at least one of the first and second fluids about a longitudinal axis of the nozzle. In one embodiment the spinner mechanism includes a LP inlet chamber connected to receive the second fluid from the LP fluid conduit, the LP inlet chamber comprising a fluid passageway that extends circumferentially around the nozzle to cause rotation of the second fluid around the longitudinal axis of the nozzle.</p> |
