INFLATOR WITH VARYING MECHANICAL ADVANTAGE

摘要

An inflator comprises a body, a first drive member, and a second drive member. The body defines a reservoir that is configured to hold fluid and includes an outlet. The first drive member is operable to move through the reservoir to drive fluid from the reservoir through the outlet. The second drive member is engaged with the first drive member. The second drive member is movable relative to the body through a first range of motion to actuate the first drive member to drive fluid through the outlet at a first rate. The second drive member is movable relative to the body through a second range of motion following the second range of motion. The first drive member is configured to either drive fluid through the outlet at a second rate or not drive fluid through the outlet as the second drive member moves through the second range of motion.

主权项

1. An inflator, comprising:
(a) a body defining a reservoir, wherein the reservoir is configured to hold a fluid, wherein the reservoir includes a fluid outlet; (b) a first drive member movably engaged with the body, wherein the first drive member is operable to move through the reservoir to selectively drive fluid from the reservoir through the outlet; and (c) a second drive member engaged with the first drive member, wherein the second drive member is movable relative to the body through a first range of motion to actuate the first drive member to drive fluid through the outlet at a first rate, wherein the second drive member is movable relative to the body through a second range of motion following the second range of motion, wherein the first drive member is configured to either drive fluid through the outlet at a second rate or not drive fluid through the outlet as the second drive member moves through the second range of motion.
