A tilt valve for an aerosol can is constructed so that it can be actuated only by transverse tilting forces. An output valve stem assembly is sealed to a valve housing whose inlet communicates with the interior of the aerosol can. A tilt element (21) is biased against the bottom of the output valve assembly so as to seal the interior of the valve housing. A barrel-shaped spring (20) is used to bias the tilt element (21) so that the resistance of the output stem (16) to tilting, and the stroke required for actuation, are reduced. The input stem (13) and the bottom of the tilt element (21) provide a secondary valve which is closed upon the output stem (16) being subject to downward axial forces. Therefore, only transverse forces provided by an automatic actuating device can be used to actuate the tilt valve assembly. |
