Abstract
An artificial respirator employs rotating chambers to modulate pressure from a unidirectional fluid source. The chambers are defined by a core rotating in a shell. The core includes an internal divider and a back wall. The core also includes a shaft coupled to a motor. The motor is mounted on the shell via screws.
