<P>PROBLEM TO BE SOLVED: To provide a highly reliable safety valve of a compressor, maintaining the valve function over a long period, by surely preventing intrusion of foreign matters into a delivery hole. <P>SOLUTION: This safety valve 30 of the compressor releases abnormal pressure to an external part via the delivery hole 32 when pressure in the compressor 1 abnormally increases, and includes: a cap 35 having an integrally bent-formed locking part 35B and detachably installed in a head part 34 of a valve body 31 via the locking part 35B; and an elastic body 36 interposed between the cap 35 and the head part 34 of the valve body 31 in a compressed state and brought into close contact with the head part 34 of the valve body 31. The elastic body 36 is interposed so as to cover the whole peripheral surface of the delivery hole 32, and the cap 35 is locked on the head part 34 of the valve body 31 by elastic resiliency of the elastic body 36, and the delivery hole 32 is closed via the elastic body 36 and the cap 35. <P>COPYRIGHT: (C)2010,JPO&INPIT |
