Abstract
A pneumatic actuator includes, but is not limited to a pressurized gas source, a cylinder, and a piston which is moveable between a rest position and an extended position. Together with the cylinder, the piston borders a first working chamber which is connected with the pressurized gas source via a first inlet opening and which can be pressurized with a first portion of the pressurized gas of the pressurized gas source for moving the piston out of the rest position, and a second working chamber which is connected with the pressurized gas source via a second inlet opening for moving the piston into the rest position and which can be pressurized in a delayed manner with a second portion of the pressurized gas.
