Reduced heat exchange reciprocating compressor

A reciprocating piston compressor, comprising:

• a crankcase that houses therein a crankshaft, set in rotation by an engine, the crankcase driving, by means of connecting rods, one or more pistons that slide within respective cylinders, above which is a valve carrier plate in which, for each cylinder, there is defined at least one inlet port, closed by an inlet valve, and at least one exhaust port, also closed by its own exhaust valve,
• wherein:
• the upper portion of said crankcase being below said valve carrier plate rises to form a head-holding turret on which said valve carrier plate rests, on the latter being located a head, reversibly connected to the upper portion of said head-holding turret by means of a plurality of clamping screws,
• in said head being defined a delivery chamber and an intake chamber placed, respectively, in correspondence with said exhaust valve and said inlet valve, and
• in the upper portion of said head-holding turret, in correspondence with said delivery chamber, one or more recesses are defined below said valve carrier plate.
