PRESSURE SENSING MEANS AND METHOD FOR A PRESSURIZED CONTAINER MEANS AND SYSTEM UTILIZING THE SAME

A container having a pressurized fluid therein and a pressure sensing fluid operated device carried by the container for sensing pressure changes within the container. The sensing device is initially charged to same pressure level as the container and is disposed within the container so as to be substantially surrounded by the fluid therein and is thereby temperature compensated whereby pressure changes of the fluid in the container caused by temperature changes thereof are ineffective to cause sensing thereof by the sensing device as the fluid of the sensing device is at the same temperature as the fluid in the container. Such container can be utilized as the fluid pressure supply means for a vehicular air bag safety device.
