摘要:
A pressure tank includes a liner separated into a cap and a main body. A shell covers the outer surface of the liner. The shell is formed of a fiber reinforced plastic. A heat exchanger is arranged in the liner. A header is connected to the heat exchanger. The heat exchanger is supported on the liner by fastening the header to the cap or the main body.

A fueling facility and method for dispensing liquid natural gas (LNG), compressed natural gas (CNG) or both on-demand. The fueling facility may include a source of LNG, such as cryogenic storage vessel. A low volume high pressure pump is coupled to the source of LNG to produce a stream of pressurized LNG. The stream of pressurized LNG may be selectively directed through an LNG flow path or to a CNG flow path which includes a vaporizer configured to produce CNG from the pressurized LNG. A portion of the CNG may be drawn from the CNG flow path and introduced into the CNG flow path to control the temperature of LNG flowing therethrough. Similarly, a portion of the LNG may be drawn from the LNG flow path and introduced into the CNG flow path to control the temperature of CNG flowing therethrough.

摘要:
A sealing plate for sealing a cartridge containing a liquified gas under pressure and having a neck with an opening with a syphon tube thereof extending from the neck into the cartridge has mounted on a side surface thereof a powdered metal cylindrical filter having a blind bore with open end closed by the plate. An integral annulus centrally disposed on the plate and projecting outwardly from a side surface of the plate mounts the filter in fixed assembly with the sealing plate. The filter is press-fitted into the annulus with its open end against the plate so that an annulus inner cylindrical surface is circumferentially disposed about the open end of the cylinder. The plate is mounted in use on the neck closing it. The cylindrical filter and the annulus around it extend into the neck and the marginal peripheral surface portion of the plate around the annulus overlies the neck closing its opening and is welded thereto to effect a seal. The sealing plate is made of a pierceable material which is pierced, when the cartridge is mounted for use in a system, to provide communication between the opening formed and the closed bore of the cylindrical filter so that a filtered liquidified gas outflow from the filter is established.
