ABSTRACT:
An automatic inflator which inflates gas-inflatable articles by the release of compressed gas from a gas-containing capsule by the piercing of a seal on the capsule. The inflator has an elongated housing having first and second end portions, the housing receiving a compressed gas-containing capsule for longitudinal movement with respect thereto and with the seal on the capsule disposed adjacent the second end portion of the housing. A piercing pin is mounted on the second end portion of the housing to confront the seal of a capsule mounted therein, there being a spring at the first end portion of the housing for constantly urging the capsule longitudinally of the housing toward the second end portion thereof. A releasable blocking device is disposed adjacent the second end portion of the housing and interposed between the seal containing end of the capsule and said second end portion of the housing to hold the seal of the capsule spaced from the piercing pin, the blocking device including a water-sensitive member which when wet releases the blocking device so that the spring moves the capsule toward the piercing pin so that the seal of the capsule is pierced thereby. The inflator is also provided with a selectively withdrawable abutment for the blocking device, whereby the capsule seal may be pierced manually.
