Zusammenfassung:Cylinder cover for reciprocating compressor, the cylinder cover comprising: at least a first expansion chamber (1) and at least a second expansion chamber (2) fluidly connected to each other by means of at least one communication duct (3); the first expansion chamber (1) being defined, at least partially, by the region (4) of the cover and the counter-parts of the compression cylinder; and the second expansion chamber (2) being defined, at least partially, by the region (5) of the cover and the counter-parts of the discharge system. The first expansion chamber (1) comprises a closing interface (11) with the valve plate arranged at the end of the compression cylinder, and the second expansion chamber (2) comprises a closing interface (21) with counter-parts of the discharge system; wherein the closing interface (11) of the first expansion chamber (1) and the closing interface (21) of the second expansion chamber (2) are oriented towards the same face, and wherein the regions (4) and (5) of the cylinder cover comprise at least one contracted section between them, said contracted section being designed to reduce resonances in the excitation frequencies of the reciprocating compressor. La presente invención se refiere a una tapa de cilindro de compresor alternativo y, más particularmente, a una tapa de cilindro provista de al menos una cámara de descarga que comprende un concepto de construcción compacta, capaz de garantizar una aplicación en compresores alternativos de diferentes capacidades, con alojamientos herméticos provistos de diferentes volúmenes internos.
