Abstract
Abstract Device in a galvanic battery for removing air, when the battery is started, from the electrolyte and water supply ducts and from the electrolyte tank, which battery has a cell system most appropriately consisting of bipolar electrode plates, in which battery there is at the juncture of the initial electrolyte supply duct, the supply duct for the electrolyte proper and the electrolyte inlet duct there is a two-position valve device having a venting duct, and that the design of the movable valve member or members is such that they move under effect of the initial electrolyte pressure into a first position in which the initial electrolyte flow has access of the inlet duct and the venting duct opens into the electrolyte supply duct, and that the movable valve members move into their second position under the pressure of the electrolyte proper, in which second position the initial electrolyte supply duct is closed and the flow of electrolyte proper has access of the inlet duct while at the same time the venting duct closes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
231 words
In combination with a galvanic battery having a cell system consisting of bipolar electrode plates, a device for removing air from the battery, said device comprising an electrolyte inlet duct connected with said cell system, a venting valve connected with said inlet duct, a second duct connected to one side of said venting valve, a third duct connected to another side of said venting valve, a first valve connected with said third duct, an initial electrolyte tank connected with said first valve, a second valve connected with said initial electrolyte tank, a pressure source connected with said second valve, a second electrolyte tank, means connecting said second and third tanks at a spaced interval to said second duct, a water supply duct connected with the second and third tanks, whereby electrolyte consisting of water and an electrolytE component is supplied to said cell system, and a two-position valve device connected with said second duct, said water supply duct and said first and second valves and having movable valve members movable under initial electrolyte pressure into a first position wherein initial electrolyte flow passes through said inlet duct and said first and second valves open into said second duct, said movable valve members being movable under electrolyte pressure into a second position wherein said third duct and said first and second valves are closed and electrolyte proper flows through the inlet duct.
Claim 2
Dependent Claim
231 words
In combination with a galvanic battery having a cell system consisting of bipolar electrode plates, a device for removing air from the battery, said device comprising an electrolyte inlet duct connected with said cell system, a venting valve connected with said inlet duct, a second duct connected to one side of said venting valve, a third duct connected to another side of said venting valve, a first valve connected with said third duct, an initial electrolyte tank connected with said first valve, a second valve connected with said initial electrolyte tank, a pressure source connected with said second valve, a second electrolyte tank, means connecting said second and third tanks at a spaced interval to said second duct, a water supply duct connected with the second and third tanks, whereby electrolyte consisting of water and an electrolytE component is supplied to said cell system, and a two-position valve device connected with said second duct, said water supply duct and said first and second valves and having movable valve members movable under initial electrolyte pressure into a first position wherein initial electrolyte flow passes through said inlet duct and said first and second valves open into said second duct, said movable valve members being movable under electrolyte pressure into a second position wherein said third duct and said first and second valves are closed and electrolyte proper flows through the inlet duct.
Claim 3
Dependent Claim
72 words
A device according to claim 1, wherein said twoposition valve device comprises a cylindrical valve body and a piston-like valve member movable in said cylindrical body, said cylindrical body having an opening communicating with said second duct, and an opposed opening communicating with said third duct, said cylindrical body having a venting aperture, said piston-like member having a venting duct which is in register with said venting aperture in said first position.
Claim 4
Dependent Claim
59 words
A device according to claim 1, wherein said venting valve comprises two separate valve members constituting check valves and movable in opposite directions, one of said check valves admitting the flow of initial adhesive into said inlet duct, the other one of said check valves admitting the flow of electrolyte proper, said other check valve having a venting duct.
Claim 5
Dependent Claim
20 words
A device according to claim 3, wherein said two check valves are located on opposite sides of said inlet duct.
Claim 6
Dependent Claim
32 words
A device according to claim 1, comprising a venting valve carried on the upper end wall of said third electrolyte tank, which closes when liquid in the tank rises to its level.
Claim 7
Dependent Claim
24 words
A device according to claim 1, comprising a narrow flow path connecting the upper part of said third electrolyte tank with said cell system.
