ABSTRACT:
An atomizer, particularly suitable for atomizing grease or lubricating compositions and useful in the foundry industry for lubricating molds, comprises a chamber in which is mounted a piston which is displaced from a rest position to an operative position by air under pressure against the effect of a spring operable to urge the piston to the rest position. Air under pressure is admitted to the chamber through an air inlet which is in constant communication with an outlet to the chamber by way of an air passage through the piston. An inlet for the composition to be atomized is controlled by a valve and opens to the chamber at a location at which it is closed when the piston is in the rest position and at which it communicates, in the operative piston position, with the air passage through a further passage provided in the piston so that the composition to be atomized is drawn by a Venturi effect into the air passage and entrained in the air flowing therethrough. The supply of the composition to be atomized is controlled by the valve and can be shut off completely so that only pressurized air is discharged.
