Aerosol valve

Claim 2

Aerosol dispenser valve comprising a unitary valve member having inlet means and outlet means, an annular wall forming an annular groove about said outlet means, scaling means engageable by said annular wall to enclose said annular groove, radial walls extending outwardly from said outlet means to said annular wall and traversing said annular groove and engageable with said sealing means to divide said annular groove into a plurality of chambers, a first orifice in a first of said chambers for interconnecting said inlet means with said first chamber, a second orifice in a second of said chambers for interconnecting said outlet means and said second chamber, and resilient spring means comprising a generally planar portion of said valve member for yieldingly urging said annular wall and said radial walls into engagement with said sealing means.

Claim 3

The invention according to claim 1 including a third orifice in a third of said chambers for interconnecting the third chamber and a source of propellant gas disposed in a container to which the valve is fixed.

Claim 4

Aerosol dispenser valve comprising a unitary valve member having inlet means, outlet means, a first chamber in communication with said inlet means, a second chamber in communication with said outlet means, said first and second chambers comprising portions of an annular groove, radial wall means traversing said groove and separating said first and second chambers, and sealing means engageable with said radial wall means, said member being movable to remove the radial wall means from engagement with the sealing means, whereby to open communication between said first and second chambers.

Claim 5

Aerosol dispenser valve comprising a unitary valve member having inlet means, outlet means, a first chamber in communication with said inlet means, a second chamber in communication with said outlet means, said first and second chambers comprising portions of an annular groove, radial wall means traversing said groove and separating said first and second chambers, and sealing means engageable with said radial wall means, said member being movable to remove the radial wall means from engagement with the sealing means, whereby to open communication between said first and second chambers.

Claim 6

The invention according to claim 3, in which said radial wall means is urged into engagement with said sealing means by a spring means.

Claim 7

The invention according to claim 4, in which said spring means comprises a leaf spring means formed as an integral part of said unitary valve member.

Claim 8

Aerosol dispenser valve comprising a valve member having a generally planar portion, a first generally circular wall upstanding from the periphery of said planar portion, a second generally circular wall upstanding from said planar portion and disposed within said first circular wall, a stem upstanding from said valve member and disposed centrally of said second wall, said stem having a discharge passage therein, an inlet tube depending from said valve member and having an inlet passage therein, said stem and said second wall forming an annular groove therebetween, radial wall means extending from said stem to said second circular wall and traversing said groove to divide said groove into a plurality of chambers including first and second chambers, said first chamber having an orifice interconnecting said first chamber and said inlet passage, said second chamber having an orifice interconnecting said second chamber and said discharge passage, and sealing means connected to said first circular wall and engageable by said second circular wall and said radial wall means, said planar portion being deformable to permit removal of said second circular wall and said radial wall means from said sealing means whereby to open communication between said first and second chambers, but urging said second circular wall and said radiaL wall means into engagement with said sealing means whereby to interrupt communication between said first and second chambers.

Claim 9

Aerosol dispenser valve comprising a valve member having a generally planar portion, a first generally circular wall upstanding from the periphery of said planar portion, a second generally circular wall upstanding from said planar portion and disposed within said first circular wall, a stem upstanding from said valve member and disposed centrally of said second wall, said stem having a discharge passage therein, an inlet tube depending from said valve member and having an inlet passage therein, said stem and said second wall forming an annular groove therebetween, radial wall means extending from said stem to said second circular wall and traversing said groove to divide said groove into a plurality of chambers including first and second chambers, said first chamber having an orifice interconnecting said first chamber and said inlet passage, said second chamber having an orifice interconnecting said second chamber and said discharge passage, and sealing means connected to said first circular wall and engageable by said second circular wall and said radial wall means, said planar portion being deformable to permit removal of said second circular wall and said radial wall means from said sealing means whereby to open communication between said first and second chambers, but urging said second circular wall and said radiaL wall means into engagement with said sealing means whereby to interrupt communication between said first and second chambers.

Claim 10

The invention according to claim 6, in which said plurality of chambers further comprises a third chamber, said third chamber having an orifice for interconnecting said third chamber and a reservoir of propellant gas.
