Abstract
A method of manufacturing a linear compressor includes measures to account for possible variations in manufacture of the spring connecting between a cylinder part and a piston part. In the method, the piston is located at a predetermined axial position in the bore of the cylinder of the compressor. A spring that is connected with the cylinder part is extended so that a piston connection point of the spring is at a position based on a predetermined displacement of the spring or a position in which the spring exerts a predetermined reaction force. In this position, this piston and the spring connection point are thus separated by a distance that depends on the actual formed dimension of the individual spring. The piston and the piston connection point are subsequently joined to have a rigid axial separation that is fixed according to the separation attained in these steps.
