Abstract
Abstract A device for dispensing a spray of fine droplets of liquid in gas. The device has a dispenser body, with a nozzle opening out of the body and having a central outlet passage and lateral passages opening into the central outlet passage. The dispenser body also has a supply chamber therein to which the lateral passages are connected. A source of pressurized liquid to be dispensed is operatively associated with the dispenser body and the dispenser body has a valved product flow path therethrough from the source of pressurized liquid to the supply chamber. A source of gas under pressure is also operatively associated with the body and the body has a compressed gas flow path therethrough from the source of gas under pressure to the supply chamber. Upon actuation, compressed gas and liquid under pressure are premixed in the supply chamber and dispensed as a spray through the nozzle.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
182 words
A device for dispensing a spray of fine droplets of liquid in gas comprising a dispenser body, said dispenser body having a nozzle means opening out of said body and having a central outlet passage closed on the end remote from the end opening out of the nozzle means and lateral passages opening into said central outlet passage, said dispenser body having an annular mixing chamber around said central outlet passage to which said lateral passages are connected, a source of liquid to be dispensed having means for mechanically pressuring said liquid and operatively associated with said dispenser body, said dispenser body having a product flow conduit therethrough from said source of pressurized liquid to said annular mixing chamber, and a source of gas under pressure operatively associated with said body and said body having a compressed gas flow conduit therethrough separate from said product flow conduit and extending from said source of gas under pressure and opening into said annular mixing chamber at a point spaced from the point at which said produce flow conduit opens into said annular mixing chamber.
Claim 2
Independent Claim
182 words
A device for dispensing a spray of fine droplets of liquid in gas comprising a dispenser body, said dispenser body having a nozzle means opening out of said body and having a central outlet passage closed on the end remote from the end opening out of the nozzle means and lateral passages opening into said central outlet passage, said dispenser body having an annular mixing chamber around said central outlet passage to which said lateral passages are connected, a source of liquid to be dispensed having means for mechanically pressuring said liquid and operatively associated with said dispenser body, said dispenser body having a product flow conduit therethrough from said source of pressurized liquid to said annular mixing chamber, and a source of gas under pressure operatively associated with said body and said body having a compressed gas flow conduit therethrough separate from said product flow conduit and extending from said source of gas under pressure and opening into said annular mixing chamber at a point spaced from the point at which said produce flow conduit opens into said annular mixing chamber.
Claim 3
Dependent Claim
45 words
A device as claimed in claim 1 in which said source of liquid comprises a measured dose dispenser having a piston-cylinder means containing the liquid to be dispensed and valve means for dispensing a measured dose of the liquid when the piston-cylinder means is actuated.
Claim 4
Dependent Claim
81 words
A device as claimed in claim 1 in which said source of compressed gas comprises an air compressing piston-cylinder means having a fixed member and a movable member movable through a compressing stroke relative to the fixed member and a valve member in said compressed air flow path mormally closing said path, actuating pin means operatively associated with air compressing piston-cylinder means and said valve member for actuating said valve member to open it near the end of the compression stroke.
Claim 5
Dependent Claim
97 words
A device as claimed in claIm 3 in which said source of pressurized liquid comprises a dispenser having a liquid pressurizing piston-cylinder means containing the liquid to be dispensed and valve means for dispensing an amount of the liquid when the liquid pressurizing piston-cylinder means is actuated, said air compressing piston-cylinder means being on one end of said dispenser body and the liquid pressurizing piston-cylinder means being on the other end of said dispenser body, and said nozzle opening laterally of said dispenser body, whereby pressure on the opposite ends of said device actuates both piston-cylinder means.
Claim 6
Dependent Claim
23 words
A device as claimed in claim 1 in which said annular mixing chamber is coaxial with the axis of said central outlet passage.
Claim 7
Dependent Claim
36 words
A device as claimed in claim 1 in which said product flow path and said compressed gas flow path open into said supply chamber in a direction parallel to the axis of said central outlet passage.
