Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
233 words
A valve for use in a gas fueled cigarette lighter comprising, in combination, a. a main outer cylindrical body secured to the upper and lower walls of a fuel reservoir tank, said main outer cylindrical body having an axially-hollow interior and a transverse opening communicating between said fuel reservoir tank and said axially-hollow interior; b. a fuel discharge nozzle mounted on the upper portion of said main outer cylindrical body, adapted to emit fuel communicated through said axially-hollow interior of said main outer cylindrical body; c. an adjusting member positioned in the axially-hollow interior of said main outer cylindrical body between said transverse opening and said fuel discharge nozzle, adaptable to change the amount of fuel communicated to said fuel discharge nozzle; d. an inner operating body arranged in said axially-hollow interior of said main outer cylindrical body in resilient contact with the lower side of said adjusting member and in rotably threaded engagement with said main outer cylindrical body, having a socket on the lower portion thereof and a transverse aperture therein communicating between said socket and said axially-hollow interior of said main outer cylindrical body; e. a valve member slidably placed in said socket of said inner operating body, having upper and lower positions and adapted to permit refueling of said lighter; and f. a spring interposed in said inner operating body to force said valve member to said lower position.
Claim 2
Dependent Claim
233 words
A valve for use in a gas fueled cigarette lighter comprising, in combination, a. a main outer cylindrical body secured to the upper and lower walls of a fuel reservoir tank, said main outer cylindrical body having an axially-hollow interior and a transverse opening communicating between said fuel reservoir tank and said axially-hollow interior; b. a fuel discharge nozzle mounted on the upper portion of said main outer cylindrical body, adapted to emit fuel communicated through said axially-hollow interior of said main outer cylindrical body; c. an adjusting member positioned in the axially-hollow interior of said main outer cylindrical body between said transverse opening and said fuel discharge nozzle, adaptable to change the amount of fuel communicated to said fuel discharge nozzle; d. an inner operating body arranged in said axially-hollow interior of said main outer cylindrical body in resilient contact with the lower side of said adjusting member and in rotably threaded engagement with said main outer cylindrical body, having a socket on the lower portion thereof and a transverse aperture therein communicating between said socket and said axially-hollow interior of said main outer cylindrical body; e. a valve member slidably placed in said socket of said inner operating body, having upper and lower positions and adapted to permit refueling of said lighter; and f. a spring interposed in said inner operating body to force said valve member to said lower position.
Claim 3
Dependent Claim
204 words
a valve for use in a gas fueled cigarette lighter comprising, in combination, a. a main outer, axially-hollow cylindrical body tightly secured by upper and lower walls of a fuel reservoir tank, said main outer cylindrical body having thereon an opening for affording open communication between said fuel reservoir tank and the hollow inner side of said main outer cylindrical body; b. a fuel discharge nozzle mounted on the upper portion of said main outer cylindrical body and adapted to communicate with said inner side of said main outer cylindrical body. c. an adjusting member provided in a middle section of the axially-hollow inner side of said main outer cylindrical body; d. an inner operating body being in resilient contact with said adjusting member and being in rotatably threaded engagement with said main outer cylindrical body; said inner operating body formed with a socket therein and an aperture thereon for connecting said socket with said axially-hollow inner side of said main outer cylindrical body; e. a valve member movably arranged in said socket of said inner operating body adapted to permit refueling of the lighter. f. a spring interposed in said inner operating body to urge said valve member to the outward direction thereof.
Claim 4
Dependent Claim
204 words
a valve for use in a gas fueled cigarette lighter comprising, in combination, a. a main outer, axially-hollow cylindrical body tightly secured by upper and lower walls of a fuel reservoir tank, said main outer cylindrical body having thereon an opening for affording open communication between said fuel reservoir tank and the hollow inner side of said main outer cylindrical body; b. a fuel discharge nozzle mounted on the upper portion of said main outer cylindrical body and adapted to communicate with said inner side of said main outer cylindrical body. c. an adjusting member provided in a middle section of the axially-hollow inner side of said main outer cylindrical body; d. an inner operating body being in resilient contact with said adjusting member and being in rotatably threaded engagement with said main outer cylindrical body; said inner operating body formed with a socket therein and an aperture thereon for connecting said socket with said axially-hollow inner side of said main outer cylindrical body; e. a valve member movably arranged in said socket of said inner operating body adapted to permit refueling of the lighter. f. a spring interposed in said inner operating body to urge said valve member to the outward direction thereof.
Claim 5
Dependent Claim
63 words
A valve for use in a gas fueled cigarette lighter according to claim 2, wherein said main outer cylindrical body comprises: a. a transverse wall provided under said fuel discharge nozzle having a bore connecting said fuel discharge nozzle with said opening of said main outer cylindrical body; and b. a sponge rubber arranged around said opening of said main outer cylindrical body.
Claim 6
Dependent Claim
68 words
A valve for use in a gas fueled cigarette lighter according to claim 2, wherein said inner operating body comprises: a. an operating section being in contact with the lower side of said adjusting member; and b. regulating means, having an axially-hollow interior, which is in rigid engagement with said operating section at the upper portion thereof and in rotatably threaded engagement with said main outer cylindrical body.
Claim 7
Dependent Claim
35 words
A valve for use in a gas fueled cigarette lighter according to claim 4, wherein said operating section includes an axial through-bore for communicating said axially-hollow interior of said regulating means with said adjusting member.
Claim 8
Dependent Claim
33 words
A valve for use in a gas fueled cigarette lighter according to claim 5, wherein said adjusting member is made of an absorbent material having mesh screens on upper and lower sides thereof.
