ABSTRACT:
A fluid actuator comprises a rigid housing having a reciprocating member, a tubular hose section having a straight length bearing against one face of the reciprocating member and connectible to a first port for introducing pressurized fluid to cause it to inflate and thereby to drive the reciprocating member rectilinearly in one direction, and a return member, e.g., a second tubular hose section, having a straight length bearing against the opposite face of the reciprocating member and connectible to a second port for introducing pressurized fluid to cause it to inflate and thereby to drive the reciprocating member rectilinearly in the opposite direction.
