Abstract
A gas cylinder residual gas volume indicator includes a carrier having a weight-receiving part and a pressure-applying part, a hydraulic cylinder having a cylinder body holding a hydraulic fluid and a cylinder piston stopped against the pressure-applying part of the carrier and movable with the pressure-applying part relative to the cylinder body to force the hydraulic fluid out of the cylinder body according to the weight received from a gas cylinder by the weight-receiving part, a hydraulic mechanical type meter having an index rotatable by a hydraulic fluid, and an oil pipe for guiding the hydraulic fluid out of the hydraulic cylinder into the meter to rotate the index.
Claims (11)
1. A gas cylinder residual gas volume indicator, comprising:
a carrier, said carrier comprising a weight-receiving part for receiving the weight of a gas cylinder and a pressure-applying part for moving a hydraulic cylinder according to the weight received by said weight-receiving part;
a hydraulic cylinder, said hydraulic cylinder comprising a cylinder body holding a hydraulic fluid and a cylinder piston stopped against said pressure-applying part of said carrier and movable by said pressure-applying part relative to said cylinder body to impart a pressure to said hydraulic fluid;
a meter, said meter being a hydraulic mechanical type meter having an index rotatable by the hydraulic fluid of said hydraulic cylinder; and an oil pipe connected between said hydraulic cylinder and said meter for guiding said hydraulic fluid out of said hydraulic cylinder body into said meter to rotate said index.
a carrier, said carrier comprising a weight-receiving part for receiving the weight of a gas cylinder and a pressure-applying part for moving a hydraulic cylinder according to the weight received by said weight-receiving part;
a hydraulic cylinder, said hydraulic cylinder comprising a cylinder body holding a hydraulic fluid and a cylinder piston stopped against said pressure-applying part of said carrier and movable by said pressure-applying part relative to said cylinder body to impart a pressure to said hydraulic fluid;
a meter, said meter being a hydraulic mechanical type meter having an index rotatable by the hydraulic fluid of said hydraulic cylinder; and an oil pipe connected between said hydraulic cylinder and said meter for guiding said hydraulic fluid out of said hydraulic cylinder body into said meter to rotate said index.
2. The gas cylinder residual gas volume indicator as claimed in claim 1, wherein said carrier comprises a movable carrier board, said movable carrier board having a top wall forming said weight-receiving part and a bottom wall forming said pressure-applying part; and said cylinder piston of said hydraulic cylinder has a distal end thereof stopped against the bottom wall of said movable carrier board.
3. The gas cylinder residual gas volume indicator as claimed in claim 2, wherein said carrier further comprises a base member;
said movable carrier board is movable up and down relative to said base member; and said hydraulic cylinder is mounted on said base member in such a manner that said cylinder piston is movable with said movable carrier board relative to said cylinder body.
said movable carrier board is movable up and down relative to said base member; and said hydraulic cylinder is mounted on said base member in such a manner that said cylinder piston is movable with said movable carrier board relative to said cylinder body.
4. The gas cylinder residual gas volume indicator as claimed in claim 3, wherein said carrier further comprises at least one spring member supported between the bottom wall of said movable carrier board and a top wall of said base member.
5. The gas cylinder residual gas volume indicator as claimed in claim 1, wherein said carrier comprises a pivoted hook member, said pivoted hook member comprising a transverse arm and a vertical arm connected at right angle, said transverse arm having a front end forming said weight-receiving part, said vertical arm having one side forming said pressure-applying part.
6. The gas cylinder residual gas volume indicator as claimed in claim 5, wherein said carrier further comprises a base member and a mounting plate mounted on said base member; said pivoted hook member comprises a pivot portion pivotally connected to said mounting plate; and said hydraulic cylinder is mounted on said mounting plate.
7. The gas cylinder residual gas volume indicator as claimed in claim 6, wherein said mounting plate has a pin hole disposed near a bottom side thereof; and said pivot portion is a pin hole cut through said pivoted hook member and pivotally connected to the pin hole of said mounting plate with a pivot pin.
8. The gas cylinder residual gas volume indicator as claimed in claim 1, wherein said meter is a Bourdon-tube manometer.
9. The gas cylinder residual gas volume indicator as claimed in claim 8, wherein said Bourdon-tube manometer comprises a dial having graduations; and said index is rotatable relative to the graduations of said dial to indicate the residual gas volume of said gas cylinder.
10. The gas cylinder residual gas volume indicator as claimed in claim 1, further comprising a guard shell surrounding the cylinder body of said hydraulic cylinder.
