protruded radially from an inner periphery thereof The limit flange 338 has a first of two
opposite sides at which the first sealing ring 335 is disposed and a second of the two opposite
sides facing the second sealing ring 336.
The inlet device 40 is fluidly connected to the gas control valve 30. The inlet device 40
includes a tube 41 and a weight 42 and the tube 41 has a first end connected to the entry port 31
and a second end connected to the weight 42. The weight 42 is suspended and movable in the
fuel container 21 under gravity. The tube 41 is flexible and changes its shape as the weight 42
moves. The weight 42 is provided with a groove 422 for allowing entrance of gas and the groove
422 and the tube 41 are at opposite ends of the weight 42. The groove 422 is connected to the
through hole 421. The groove 422 extends longitudinally in a direction perpendicular to the
through holes 421.
The inlet device 40 includes a first connecting sleeve 43 and a second connecting sleeve
44 surrounding an outer periphery of the tube 41. The first connecting sleeve 43 is connected to
the entry port 31 and inserted into the input passage 331. The weight 42 is provided with a
through hole 421 extending therethrough. The second connecting sleeve 44 is connected to the
weight 42 and inserted into the through hole 421.
The gas control valve 30 includes an adapter 36 connected to the exit port 32 and
capped on the injection mouth 34. The adapter 36 is provided with a perforation 361 is
communicated with the output passage 342. The adapter 36 is engagable with a nail gun (not
shown) and configured to allow the nail gun to operably move the injection mouth 34 for
dispensing gas to the nail gun.
With the above-mentioned structure, the gas canister 10 does not need a gas bag in the
housing 20 because it can still operate normally in a tilted state. Further, since the tube 41 is
flexible, the weight 42 can move in the fuel container 21 under the influence of gravity. When
the gas canister 10 is tilted (Fig. 8) or moved upside down (Fig. 9), the weight 42 is in a
corresponding movement to cause the end of the tube 41 that is opposite to the gas control valve
30 to be kept below the liquid level 91 of the liquid gas 90. Accordingly, the gas canister 10 can
be operated effectively at any angle to deliver gas.
The groove 422 allows the liquid gas 90 to pass through. So if an end of the weight 42
that is opposite to an end at which the tube 41 is disposed is in contact with the inner surface of
the housing 20 and the through hole 421 is perpendicular to the inner surface of the housing 20,
the groove 422 allows entrance of the liquid gas 90 to the through hole 421.
When the injection mouth 34 is in the closed position, the liquid gas 90 can be delivered
to the gas control valve 30 through the liquid inlet device 40, the liquid gas 90 is accumulated in the storing compartment 332 after passing through the first recess 341 and the first side channel
343, and the second sealing ring 336 can prevent gas leakage. When the injection mouth 34 is in
the open position, the first sealing ring 335 blocks the liquid gas 90 from entering the storing
compartment 332, the liquid gas 90 in the storing compartment 332 can flow thereout from the
second side channel 344 and the output passage 342. In this embodiment, the storing
compartment 332 forms a space configured for accumulation of the gas delimited by the inner
periphery of the spacer ring 337 and the first and the second sealing rings 335 and 336.
Moreover, since the space enclosed by the spacer ring 337, the first sealing ring 335 and the
second sealing ring 336 has a fixed size, each time the injection mouth 34 is pressed, only a fixed
amount of gas can be dispensed.
In summary, the bagless gas canister 10 for a gas nail gun in accordance with the present
invention is adapted to dispense gas without the use of a gas bag in the housing 20 because it
includes the housing 20 including the fuel container 21 therein and the gas control valve 30
coupled to the housing 20. The gas control valve 30 is provided with an entry port 31 and an exit
port 32. The entry port 31 is disposed in the fuel container 21 and the exit port 32 is disposed
outside the fuel container 21 respectively. An inlet device 40 is fluidly connected to the gas
control valve 30. The inlet device 40 includes a tube 41 and a weight 42 and the tube 41 has a
first end connected to the entry port 31 and a second end connected to the weight 42. The weight
42 is suspended and movable in the fuel container 21 under gravity. The tube 41 is flexible and
changes its shape as the weight 42 moves.
