Abstract
One or more examples of the gas boosters described herein aim to provide a light weight gas booster configured to produce high output pressure levels at high volumes. Generally described, one or more examples of the gas boosters reduce the dead volume in a piston assembly, thereby increasing the ratio of the output pressure to the input pressure. In that regard, several examples of the gas boosters disclosed herein have a first check valve as a disk-type check valve or the like and a second check valve as a ball-type check valve or the like. Furthermore, one or more examples include an inwardly acting cam configured to convert rotary motion to reciprocating motion by an inner surface thereof.
