Abstract:
A fuel cartridge (1), which is capable of being mounted on a tool main body of a gas-combustion type driving tool (B) so as to supply fuel gas to a striking mechanism of the tool main body, is provided with an ejection nozzle (4) provided at a port portion formed at an end portion of a cartridge main body (1) and slidable with respect to the cartridge main body (1); a compression spring (16) for biasing the ejection nozzle (4) so that a tip end of the ejection nozzle (4) protrudes from the cartridge main body (1); and an ejection hole (17) formed at a side wall of a tip end portion of the ejection nozzle (4).
Abstract:
A tank (2) has a shell (3) defining an inner chamber (4), which contains liquefied petroleum gas and houses a member (10) that is moveable in order to vary the volume available for the liquefied petroleum gas; said member preferably being defined by an inflatable bag (10).
Abstract:
The invention relates to a hydraulic accumulator, in particular a bladder accumulator, comprising two at least partially adjacent plastic casings (12, 14). The first plastic casing (12) comprises a collar part (16) at least at one end thereof. The aim of the invention is to produce a leakproof accumulator arrangement which is economical to produce. To achieve this, a gap opening (24) between the casings (12, 14) extends up to a point, at which the casings (12, 14) are positioned together in a coaxial manner, and a disk valve (50) is provided as a valve for controlling the supply and discharge of the medium in the opening (10).
Abstract:
A receiving part (11) having a pressure receiving face (11F) is provided in the through hole (10) of a container body (1), wherein the pressure receiving face has a tapered pressure receiving face (11A) and an outer receiving pressure regulating R face (11B) continuous to the forward end of the tapered pressure receiving face (11A). A supply/discharge tube (13) being inserted into the through hole is provided with a flange part (14) having a pressurizing face (14F) which is provided with a tapered pressurizing face (14A) coming into face contact with the tapered pressure receiving face.
Abstract:
Described herein is a portable storage device that stores a hydrogen fuel source. The storage device includes a bladder that contains the hydrogen fuel source and conforms to the volume of the hydrogen fuel source. A housing provides mechanical protection for the bladder. The storage device also includes a connector that interfaces with a mating connector to permit transfer of the fuel source to a device such as a laptop computer. The refillable system comprises a hydrogen fuel source refiller that includes the mating connector and provides the hydrogen fuel source to the storage device. Hot swappable fuel storage systems described herein allow a portable hydrogen fuel source storage device to be removed from a fuel processor or electronics device it provides the hydrogen fuel source to, without shutting down the receiving device or without compromising hydrogen fuel source provision to the receiving device for a limited time.
Abstract:
A fluid pressurization device 10 comprises a pressure container 12 and a first bladder 14, asecond bladder 16 and a sheet 18, that are located in the pressure container 12. The bladders14 and 16 have pipe connectors 32 and 40, respectively, for filling/discharging fluid from thebladders. The bladders 14 and 16 are located in the container 12 adjacent one another, withthe bladder 16 being folded in concertina fashion and the sheet 18 being wrapped around thebladder 16 to form a roll surrounding the folded bladder 16. In use, the bladder 14 is filled with a combustible fluid such as oxygen and the bladder 16 is filled with compressed air to a relativelyhigher pressure than the oxygen in the bladder 14 for pressurizing the oxygen contained therein.As oxygen is delivered from bladder 14, the sheet 18 unravels gradually, allowing the bladder 16to continue to exert a force on the bladder 14.
Abstract:
A container (1) having a first compartment (3) and a second compartment (5) separated by a movable gas impermeable partition (7) is used for storing and dispensing a gas for use in a process and receiving and storing a gas recovered from the process. Fresh gas is dispensed (9) from the first compartment (3) for use in a process and recovered gas is fed (11) to the second compartment (5), whereby a volume of the second gas displaces a volume of the first gas by movement of the partition (7) to enlarge the second compartment (5) relative to the first compartment (3).
