Abstract: Reciprocating-type compressor for refrigeration and/or conditioning and/or heat pump systems, comprising—a casing in which there is defined at least one compression section comprising at least one cylinder and a corresponding compression piston, —a head provided on said casing, defining a delivery chamber immediately down-stream of said compression section, and adapted to receive the compressed fluid from said compression section, —an intake zone from where the fluid to be compressed in the at least one cylinder of said compression section is introduced, —a delivery tap at the operational outlet of said compression chamber, characterized in that it comprises a check valve placed between said operational outlet of said compression chamber and said delivery tap, adapted to prevent the return of fluid into the compression chamber from said delivery tap.
