Abstract

A valve assembly is disclosed for use in an aerosol spray can capable of spraying viscous materials or materials with large particulates without clogging or packing like traditional aerosol spray cans designed for spraying texture materials. The valve opening may be located at substantially any point between the bottom and the top of the container. The valve assembly includes a side-fitting dip tube and a side-feeding mechanism, whereby texture material is dispensed when a central channel is aligned with a side conduit that is in flow communication with the dip tube. This allows highly-viscous materials, such as a fire suppressant material, or materials having large particulates, such as stucco, to be sprayed from an aerosol spray can without clogging. The valve assembly also includes a guiding mechanism to ensure alignment of the central channel and the side conduit in the actuated position.

Dependent claims

A valve assembly for use in an aerosol system, said valve assembly comprising:

an upper housing defining a first opening through the periphery thereof;
a side conduit having a free end, and an end that is connected to said first opening at an angle sloping downward from the horizontal;
a lower housing divided into a vertical passageway and a vertical compartment, wherein said passageway has an upper end and a lower end and said upper end is in flow alignment with said free end of said side conduit so as to provide flow communication between the lower end of said passageway and said first opening;
and
an actuating mechanism having a spool defining a length-wise channel through a portion thereof, wherein said spool is configured to move vertically within said upper housing and said vertical compartment, and wherein a lower portion of said channel is angled so as to be in flow alignment with said conduit through said first opening when the actuator assembly is in an actuated position, thereby allowing a sprayable material to flow through said passageway, conduit, and channel.
