Abstract
A reversible fluid unit which may be used as a motor, pump, brake or clutch. The unit has a plurality of sequentially inflatable diaphragms, to impart a rotative force to a plurality of roller members. When used as a motor, brake or clutch, air under pressure is sequentially fed to the plurality of diaphragms which inflate against roller members connected to a driven output shaft. As the diaphragms inflate, the roller members are contacted by the inflated diaphragms to impart or brake rotary motion thereto. When used as a pump, the rollers are rotated to pump air out through the diaphragm members.
