Magnetic coupling pneumatic linear motion actuator

A magnetic coupling pneumatic linear motion actuator comprising:

• a. a tube having a longitudinal end and an oppositely longitudinal end;
• b. a magnetic piston slidably mounted within the tube;
• c. a magnetic sleeve and sleeve passage annulus combination, said combination's magnetic sleeve being slidably mounted over the tube;
• d. longitudinal and oppositely longitudinal shoulders fixedly attached to or formed wholly with the tube, the longitudinal shoulder extending radially inwardly from the tube's longitudinal end, and the oppositely longitudinal shoulder extending radially outwardly from the tube's oppositely longitudinal end;
• e. a longitudinal end cap positioned at the tube's longitudinal end, the longitudinal end cap being adapted for releasable attachment to the longitudinal shoulder;
• f. an oppositely longitudinal end cap positioned at the tube's oppositely longitudinal end, the oppositely longitudinal end cap being adapted for releasable attachment to the oppositely longitudinal shoulder;
• g. a piston passage port;
• and
• h. a push rod passage port, wherein the piston passage port is positioned radially inwardly from the oppositely longitudinal shoulder, wherein the sleeve passage annulus extends radially outwardly from the longitudinal shoulder, and wherein the push rod passage port is positioned radially inwardly from the longitudinal shoulder.
