Jet assisted tubeless tire seating device

摘要

A nozzle for seating a tubeless tire on a rim using pressurized gas includes an outlet, a jet configured to accept pressurized gas and emit a stream of gas through an orifice into a chamber. As the stream of gas enters the chamber, the Venturi effect causes air to enter the chamber through air intake ports and the stream of gas and air from the air intake ports is blown out of the outlet of the nozzle. A system for seating a tubeless tire on a rim includes the nozzle, a tank and a valve configured to control the flow of pressurized gas from the tank to the nozzle. The tire may be seated on the rim by positioning the system so that the air from the nozzle blows into the tire between the bead of the tire and the rim if the valve is opened.

主权项

1. A nozzle for seating a tubeless tire on a rim using pressurized gas, the nozzle comprising:
a jet configured to accept the pressurized gas and emit a first stream of gas through an orifice; an outlet suitable for directing a second stream of gas into a gap between the tubeless tire and the rim; a chamber extending into the nozzle from the outlet and situated to allow the stream of gas to enter the chamber, the chamber having a cross sectional area at a point near where the stream of gas enters the chamber that is larger than the orifice, said cross sectional area measured in a direction substantially perpendicularly to a direction of flow of the first stream of gas as it is emitted from the orifice; and at least one air intake port situated to allow air from outside the nozzle to enter the chamber and be emitted from the outlet if the stream of gas is flowing from the orifice, through the chamber and out of the outlet; wherein the second stream of gas comprises the first steam of gas and said air from outside the nozzle.
