Abstract

PURPOSE:To improve the seal function by putting a seal member having an opening hollowed out in a dish shape at the center and with a nearly V block shaped cross section in a cavity between a seal cover and a seal ring so that both ends of the opening of the seal section get into contact by pressure with the seal face. CONSTITUTION:A cone ring 12 which is a seal member having an opening 15 hollowed out in a dish shape at the center and with a nearly V block shaped cross section is put in a cavity formed between a seal cover 2 and a seal ring 3. The cone ring 12 is arranged so that the opening 15 of the nearly V block shaped cross section portion 13 is faced to the acting direction of a of the internal pressure and both ends 16 of the opening 15 get into contact with the seal face 4. Thus, by tightening individual hexagon socket head cap screws 6 during fabrication, even if the work precision of the seal face 4 is inferior, both ends 16 of the opening 15 are pressed easily and for sure to the seal face 4 with a uniform face pressure by means of the elastic force of the nearly V block shaped cross section portion 13 of the cone ring 12, and the seal function can be improved.
