ACTUATOR HAVING DUAL PISTON SURFACES

摘要

A pressurized-fluid-operated actuator (10) includes a tubular outer cylinder (32) defining an inner cylindrical surface and a piston (30) slidably carrie d within the outer cylinder. A rod (28) is affixed to the piston (30), the rod extending from an end of the piston in an axial direction relative to the outer cylinder. The piston (30) is divided into two inner chambers (110, 112 ) by a stationary inner dividing wall (64) that is rigidly connected with a cylinder end wall.
