摘要:
A fuel transfer adapter for a fuel cartridge, the fuel transfer adapter comprising: an adapter body; at least one fuel filling channel through said adapter body for the passage of fuel from a valve of the fuel cartridge to a fuel tank of an appliance through a filling port of said fuel tank; a fuel cartridge engaging portion at one end of the adapter body, for engaging the adapter body with the valve of the fuel cartridge; and, a port engaging portion at the other end of the adapter body for releasably engaging with the filling port, whereby the fuel transfer adapter incorporates at least one vent for the passage of vapour from the fuel tank to the atmosphere, said at least one vent being configured, in use, to transfer vapour displaced from the fuel tank by the fuel entering therein to the atmosphere.A method of filling a fuel tank of an appliance comprising the steps of: docking a fuel cartridge equipped with a fuel transfer adapter to a filling port of an appliance; applying a push force between the appliance and the fuel cartridge to open both a port filling valve and a fuel cartridge valve; applying a further push force between the appliance and the cartridge to create a fluid-tight seal between a compliant rim of the fuel transfer adapter and the filling port, and to create a fluid-tight seal between the sealing lip of a port engaging portion of the fuel transfer adapter and a wall of the filling port; allowing fuel to transfer from the fuel cartridge to the fuel tank of the appliance, and displaced vapour to transfer from the fuel tank to the atmosphere through a vent in the fuel transfer adapter; and, undocking the fuel cartridge from the filling port.

A fuel can adapter has a threaded section for threadly engaging with a fuel device. Particularly, the fuel device has a threaded joint for engagement with the thread section of the fuel can adapter. In addition, this threaded joint can be used to connect a fuel can with a thread head, such that fuel in the fuel can can flow to the fuel device. With the fuel can adapter, a fuel can with a head, which does not have a threaded head but has a flange extending circumferentially thereon, is adapted to connect to the fuel device, such that fuel in the fuel can can flow to the fuel device.

Described here are devices including gas cylinders for use in various applications. The applications may comprise the dispensing and administration of a compressed gas to the nasal mucosa of a user. The devices generally include an integral valve comprised of a valve seat and a valve pin. The orifice of the valve seat may be configured to limit the flow rate of the gas.

A system for identifying the time remaining for a bottled gas supply to lapse. Such bottled gas supplies include those used for gas grilles, scuba, nitrogen for electron microscopes, and any other environment in which a bottled gas is used. The system reads the pressure and optionally the temperature of the gas container, the readings of which are read by a microprocessor, optionally first pre-processed in a conversion module, and converted into a display for the user identifying the time during which the gas contents remaining will last. In various systems, it may be desirable to program the microprocessor, such as with input from a keyboard and/or cd-rom, with parameters regards specifics of the gas or the container, or to simply processing by assuming a certain temperate correlation and thereby eliminate the need for a temperature transducer.
摘要:
Manifold/distributor assembly for combustible gas supplied from a plurality of liquefied gas cartridges, comprising a frame (1) with upper and lower covers (64, 65) forming a leaktight box (95) and, within the box, a plurality of housings (2), each for housing a liquefied gas cartridge (36, 85) and each one being provided with a valve assembly (71) incorporating an actuation element (13, 91), which valve assembly does not open unless a cartridge is present in the housing and actuates the element; the outlet of each valve assembly being connected to a manifold (15, 16, 17, 18, 73, 74, 75, 76, 77, 78, 79) comprising a multiple-way tap (80) for selective connection of manifold portions to a delivery pipe (22), in case through a pressure regulator (81).
摘要:
A liquified petroleum cylinder has a reserve cylinder within it provided with a separate outlet external to the main cylinder. The reserve cylinder may be provided with a non-return valve (not shown in FIG. 1), whereby both cylinders may be filled with gas through the same external valve.

There is disclosed a valve for controlling flow of gas and for use with portable gas appliances such as picnic stoves, heaters or lamps. The valve is associated with an adaptor having a projection arranged for operating an outlet valve in a refillable gas container when the adaptor is threaded on to the container. The valve body has an inlet including a pin for operating the valve of a self-sealing gas cartridge.
摘要:
An improved connection head for use in a portable lighting or cooking or heating device burning gas from a replaceable cartridge which has in one of its walls a check valve inwardly displaceable to release stored gas to the connection head, the head comprising a casing having a bore disposed opposite said cartridge check valve, a sleeve reciprocable in the casing bore, a rod extending through the casing and the sleeve coaxially therewith, spring means urging the rod toward the cartridge to displace its check valve, the sleeve having annular packing disposed to seal against the wall of the cartridge around the check valve, and these parts being provided with inter-engaging abutments such that the spring means urges the rod toward the check valve and the rod urges the sleeve to seal against the wall of the cartridge around the check valve, the force of the spring being sufficient to displace the check valve but insufficient to puncture the wall of a cartridge, and the rod having a conical surface operative with said annular packing to control the rate of flow of gas from the cartridge.
