摘要

PURPOSE: To provide an aerosol valve which can also be used as a fixed volume blowoff valve and reduce the number of parts and assembling man-hour by mounting a fixed volume chamber closing insertion pin of a fixed volume chamber closing member detachably to a valve stem. ;CONSTITUTION: A fixed volume chamber closing insertion pin 8 of a fixed volume chamber closing member 7 is detachably mounted to a valve stem 2. And for use as a general aerosol valve, the pin 8 is removed from the valve stem 2. On the other hand, for use as a fixed volume blowoff valve, the pin 8 is mounted to a proper point of the stem 2 to effect fixed volume blowoff. And a wide groove having a desired length is formed downwardly from the upper end of the outer side of a housing 6 serving as a base of a plurality of elastic rising pieces 12 provided integrally upwardly for supporting a block 5 at the lower part of the stem 2 to effect pressurization for a short time utilizing the groove.;COPYRIGHT: (C)1996,JPO
