Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
128 words
A PRESSURE TRANSDUCER FOR ACCURATELY MEASURING THE PRESSURES ENCOUNTERED IN COMBUSTION CHAMBERS, SAID TRANSDUCER COMPRISING: A CLAMPED DIAPHRAGM; APPARATUS FOR MOUNTING SAID CLAMPED DIAPHRAGM SO THAT ONE SURFACE THEREOF IS EXPOSED TO THE COMBUSTION CHAMBER; A PLURALITY OF FOUR STRAIN GAUGE ELEMENTS INTERCONNECTED TO FORM A BRIDGE NETWORK MOUNTED ON THE OTHER SURFACE OF SAID DIAPHRAGM; AN ANNULAR-SHAPED CAP DEVICE FITTED OVER SAID DIAPHARGM; AND CONTIGUOUS THERETO, SAID DEVICE BEING FORMED TO PROVIDE A NARROW AIR GAP BETWEEN IT AND SAID DIAPHRAGM NEAR THE EDGE THEREOF; AND MEANS FOR PROPELLING A SPIRALLING COOLANT LIQUID INTO THE SPACE AROUND SAID DIAPHRAGM AND FORWARD THROUGH SAID AIR GAP, WHEREBY SAID COOLANT LIQUID IS VAPORIZED TO FORM AN ATOMIZED FILM COOLANT ZONE INSIDE THE COMBUSTION CHAMBER THAT PROTECTS THE TRANSDUCER COMPONENTS.
