Abstract
An actuator is provided. The actuator includes: a housing having an interior elongated hole; a rod dimensioned to fit in the elongated hole; a piston dimensioned to fit in and move along the elongated hole while connected to the rod; mating structure located on at least one of the piston and rod, the mating structure configured to allow the rod to attach to the piston in a manner to create clearance between the rod and the piston to allow the rod and piston to move with respect to each other. A method of attaching a piston to a rod in an actuator may also be provided. The method may include: fitting the piston to the rod; providing a clearance between the piston and the rod; fastening the piston to the rod in a loose manner as to preserve the clearance and allow the piston to move with respect to the rod.
