ABSTRACT:
The pneumatic actuator comprises at least one double-acting cylinder having a tubular body and two closure heads which define a piston chamber for a reciprocable piston; the body of the cylinder consists of an extruded tubular section provided with at least one longitudinal conduit for the air flow, which extends in a wall between the two end portions of the tubular body. One of the closure heads at an end side of the tubular body is provided with air-flow passage for connecting one end of the piston chamber via said longitudinal conduit to an air inlet/outlet opening close to the other end side of the body. The second closure head of the cylinder is in turn provided with an air inlet/outlet opening connected to the end of the piston chamber which is opposite the previous one. The actuator is made in the form of a single cylinder or of a telescopically extending cylinder having several stages.
