Abstract
PURPOSE: To secure sure sealing and to allow simple and precise fastening of a diaphragm by forming the rim of the diaphragm thinner than the inner part of the diaphragm and forming in a bonnet a step of a height corresponding to the difference between the thicker part and the thinner part of the diaphragm.
CONSTITUTION: The head of a diaphragm 2 is fitted in a compressor 6. The bolt holes of the diaphragm 2 are aligned with the corresponding bolt holes of a bonnet 4, then the thin part 2c of the diaphragm 2 fits in the inner stepped part 4c formed on the bonnet 4 and the sealing surfaces 2b and 4b of the diaphragm 2 and the bonnet 4 lie one upon another. The bolt holes of the diaphragm 2 and the bonnet 4 are aligned with the bolt holes of the body 1, then bolts 3 are inserted through the holes from under and the bonnet 4, diaphragm 2 and body 1 are fastened together by nuts 5 screwed on the respective bolts 3 from a above by an appropriate torque. This constitution not only closely joins the respective sealing effect by the close adhesion between the inner thicker part 2c of the diaphragm 2 and the stepped part 4c of the bonnet 4.
