Abstract
A nozzle for providing carbon dioxide for cleaning is disclosed. The nozzle includes a reservoir for receiving liquid carbon dioxide, a barrel defining a passageway therethrough, the passageway extending to an outlet of the barrel, an orifice effecting fluid communication between the reservoir and the passageway, and a screen member constructed and arranged for interrupting flow of the carbon dioxide pellets greater than a select size from being emitted from the passageway of the barrel. Liquid carbon dioxide flows through the orifice to phase transfer into gaseous carbon dioxide and carbon dioxide pellets in the passageway. An internal diameter of the passageway is smaller than an internal diameter of the reservoir.
Claims24
A nozzle for providing carbon dioxide for cleaning, comprising:
- a reservoir for receiving liquid carbon dioxide;
- a barrel defining a passageway therethrough, the passageway extending to an outlet of the barrel, an internal diameter of the passageway being smaller than an internal diameter of the reservoir;
- an orifice effecting fluid communication between the reservoir and the passageway, and through which the liquid carbon dioxide flows to phase transfer into gaseous carbon dioxide and carbon dioxide pellets in the passageway;
- a screen member constructed and arranged for interrupting flow of the carbon dioxide pellets greater than a select size from being emitted from the passageway of the barrel;
- and
- the barrel further comprises a plurality of apertures extending therethrough a wall of the barrel.
A nozzle for providing carbon dioxide for cleaning, comprising:
- a housing having an outlet;
- a reservoir for liquid carbon dioxide within the housing, an internal diameter of the outlet being smaller than an internal diameter of the reservoir, the reservoir being in communication with the outlet and having a reduced diameter approaching the outlet for facilitating the phase transfer of the liquid carbon dioxide into gaseous carbon dioxide and carbon dioxide pellets;
- and
- a screen member disposed downstream in a direction of carbon dioxide flow from the outlet for interrupting flow of carbon dioxide pellets greater than a select size from being emitted from the screen member.
A nozzle for providing carbon dioxide for cleaning, comprising:
- a reservoir for receiving liquid carbon dioxide;
- a barrel defining a passageway therethrough, the passageway extending to an outlet of the barrel, the barrel being free from overlap with the reservoir along a longitudinal axis of the barrel;
- an orifice effecting fluid communication between the reservoir and the passageway, and through which the liquid carbon dioxide flows to phase transfer into gaseous carbon dioxide and carbon dioxide pellets in the passageway;
- and
- a screen member constructed and arranged for interrupting flow of the carbon dioxide pellets greater than a select size from being emitted from the passageway of the barrel;
- and
- the barrel further comprises a plurality of apertures extending therethrough a wall of the barrel.
