Automatic actuator assembly for aerosol containers

Abstract

An automatic actuator is provided for conveying the pressurized fluid from an aerosol container into an automotive system such as an air conditioner or a pneumatic tire. The preferred actuator comprises a selectively rotatable first subassembly equipped with a coupling device to be rapidly engaged and locked onto a conventional fitting of the automotive system and a first force transmitting member disposed inside a generally cylindrical channel and the transmitting member is movable along the channel to operate the valve of a charging port of an automotive system. Another end of the core depressor is in an interlinked relation with a second force transmitting element disposed inside the base portion of the adapter. An assembled adapter provides an uninterruptible link between two force transmitting elements such that, when the assembly is fitted onto an aerosol can and a coupling device is locked onto the charging fitting of an automotive system, the first transmitting element opens the charging valve. The reacting force from this action is transferred to the second force transmitting element which in turn opens a valve of an aerosol can, allowing fluid to escape from the can through the internal channel formed using the assembled adapter, into the system to be charged. The pressure proof joint of the two sub assemblies is provided by a rubber o-ring and snap-on assembly elements that allow the selective rotation of the coupling portion of the adapter around the base and at the same time prevent the escape of fluids. The coupling portion of the adapter can be positioned at any angle from 90 degrees to 180 degrees relative to the can. A rubber seal fitted inside the base portion of the adapter and resting upon the top face of the can provides a leakage proof fitting between the adapter and an aerosol can.

1 . An automatic actuator assembly for aerosol containers comprising: 
 a base subassembly and coupler subassembly, and an interior channel formed by hollow chambers of said subassemblies through a sealed joint, said coupler subassembly to be sealingly and rotatably connected to a base subassembly, said coupler to be sealingly engaged and locked with a charging port of an automotive system, said base to be sealingly attached to a valve end of a pressurized aerosol container;    a first force transmitting member disposed inside a hollow chamber of the coupler and a second force transmitting member disposed inside a hollow chamber of the base, said force transmitting members always being in the interlinked relation at the angle of 135 degrees to each other disregarding their position in relation to a charging container;    wherein any displacement of said first force transmitting member causes equal displacement of the second force transmitting member, thus when applied to a charging port of an automotive system such interaction causes both valves to open automatically and quasi-simultaneously.
