1. , a kind of pressure unit that is used to measure from the next hydraulic pressure of pressure source, it comprises:

  • A seat cover has a seat cover outer rim of surrounding seat cover inner edge, and this seat cover inner edge limits the perforate of a seat cover;

    The mechanism that sensed pressure is used is provided with in the present cover, sensor output is provided and is coupled to seat to cover in the perforate;

    Ring flange mechanism, be used for hydraulic pressure is coupled to the mechanism that sensed pressure is used, has a ring flange outer rim near corresponding seat cover outer rim, this ring flange mechanism has a ring flange inner edge, this inner edge surface is to a corresponding seat cover inner edge and a qualification recess therebetween, this ring flange mechanism has a passage, this passage is communicated to the first ring flange perforate of hydraulic pressure from be defined in ring flange mechanism in the second ring flange perforate that is limited by the ring flange inner edge, and this second ring flange perforate is coupled to hydraulic pressure in the mechanism that sensed pressure uses;

    Sealing mechanism is arranged in the recess, is used for that seat is covered inner edge and is sealed in the ring flange inner edge;

    Retention mechanism is connected in the ring flange mechanism, is used for ring flange outer rim and seat cover outer rim are tightened together, and make seat cover outer rim accept a fastening force from the ring flange outer rim, and seat cover inner edge is accepted a sealing force by sealing mechanism from the ring flange inner edge;

    AndBending mechanism is limited by at least one groove between seat cover inner edge and seat cover outer rim in the seat cover, is used to reduce fastening force transmission with mechanism from seat cover outer rim to sensed pressure.
