Patent ID: 8171799

Claim:
A pressure sensor including a body with a pressure chamber for receiving a fluid and a support element around said chamber, a cover secured to the body and provided with a stop strip that has a closed contour in correspondence with the support element of the body, a diaphragm, which is arranged between the body and the cover to seal off the pressure chamber, and which bends under the effect of a pressure difference between the two surfaces thereof, with a peripheral region of the diaphragm arranged between said support element and said stop strip, and transmission means, connected to a central region of the diaphragm for transmitting diaphragm deflection data to measuring or indicating means, wherein the diaphragm has a generally flat shape, in that the peripheral region of the diaphragm pivots on the stop strip when the diaphragm bends under the effect of an increase in fluid pressure in the pressure chamber, in that said support element is a sealing gasket mounted on the body and compressed between the body and the peripheral region of the diaphragm to press said peripheral region permanently against the stop strip, and in that the sealing gasket is located opposite the stop strip.
