Fig. 3.7: Symbol for diaphragm compressor |The diaphragm compressor belongs to the family of displacement compressors.|
An elastic diaphragm causes the compression. Instead of a piston moving linear between two end positions, the diaphragm is moved in non-linear vibrations. The diaphragm is attached to the side and is moved by a con-rod. The stroke of the con-rod depends on the elasticity of the diaphragm.
