Aerosol valve device
First Claim
1. An aerosol valve device, suitable in particular for use with spray canisters or other containers from which liquid can be forced out in the form of a fine mist, using compressed gas as a propellent, said valve device comprising:
- an aerosol valve;
a connector;
a riser tube connected to the connector;
a two-way valve provided between the aerosol valve and the connector, said two-way valve comprising a body with a central bore, in which two opposed valve seats are formed to seat an elongated valve member moveable between said valve seats;
automatic actuating means for actuating said valve member, which control the valve member depending on the position of the container;
said valve member cooperating with one valve seat to clear a connection between the riser tube and the aerosol valve and simultaneously to block a connection between the direct surroundings of the two-way valve and the aerosol valve, and said valve member cooperating with the other valve seat to block the connection between the riser tube and aerosol valve and at the same time to clear a connection between the direct surroundings of the two-way valve and the aerosol valve;
said valve member being made of magnetizable material and said automatic actuating means comprise a member disposed about the body of the two-way valve, which actuating means is at least partly permanently magnetic and can move freely along the body through a path corresponding to the patch between the two valve seats.

Abstract
An aerosol valve device for use with spray canisters using compressed gas as a propellant. The valve device comprises an aerosol valve and a connector for a riser tube which, in the operative condition, extends nearly to the bottom of an aerosol container. A two-way valve is provided between the aerosol valve and the connector. The two-way valve comprises a body with a central bore, in which two opposed valve seats are formed to seat a valve member movable to and fro between said valve seats, and an automatic actuating element for actuating said valve member control the valve member depending on the position of the container. The valve member cooperates with one valve seat to clear a connection between the riser tube and the aerosol valve and simultaneously to block a connection between the direct surroundings of the two-way valve and the aerosol valve, and cooperates with the other valve seat to block the connection between the reiser tube and the aerosol valve and at the same time to clear a connection between the direct surroundings of the two-way valve and the aerosol valve.
