  • Patent number: 6880733
    Abstract: An aerosol vessel, which can be prevented from deforming and exploding by discharging gas when an excessive pressure occurs in a main body, is provided. The aerosol vessel includes a valve assembly basically including a nozzle body fixed to the main body; a valve stem installed at the nozzle body such that it can move up and down and has a gas inlet and a gas ejection passage; an opening/closing ring installed between the nozzle body and the valve stem such that it contacts and is removably supported by a support sill of the nozzle body in order to open or close the gas inlet; and an elastic unit for restoring the valve stem after operation and elastically supporting the opening/closing ring with respect to the support sill. When an excessive pressure occurs in the main body, the opening/closing ring moves upward and overcompressed gas is discharged through the gas inlet or a gap between the valve stem and a support member.

  • Publication number: 20040079410
    Abstract: Provided is a hydrostat for a portable gas range, which prevents the explosion of a gas container by automatically discharging overcompressed gas from the gas container when the inner pressure of the gas container increases to an explosion pressure. The hydrostat includes a body which is installed below a governor valve of the portable gas range. The body includes a gas outlet, which communicates with a gas inlet of the governor valve, and a sealed room, which communicate with the gas outlet. An opening/closing unit is installed within the sealed room of the body such that it can elastically move up and down in order to discharge overcompressed gas by opening the gas outlet when the inner pressure of the gas container reaches or exceeds a threshold value of deformation. A cap is removable fixed at the bottom of the body using a screw so as to adjust the elasticity of the opening/closing unit and has a discharge hole for discharging overcompressed gas, which escapes the gas container through the gas outlet.
