Claim 15:
16. The refrigeration apparatus according to claim 12, wherein said reciprocating compressor comprises an additional piston integrally constrained to said rod and translatable within said cylinder, wherein said cylinder is provided with an additional first chamber comprising an additional first port for the inflow of the coolant coming from said evaporator and an additional second port for the outflow of the compressed coolant contained in said additional first chamber to reach said main compressor, said cylinder further comprising an additional second chamber fluidically separated from said additional first chamber by said additional piston and being provided with an additional third port for the inflow of an additional portion (X2′) of said fraction (X1) of coolant in order to displace said additional piston and compress said coolant contained in said additional first chamber and allow the simultaneous suction of coolant from said evaporator into said first chamber, and with an additional fourth port for the outflow of said additional portion (X2′) of said fraction of coolant (X1) at the end of the compression of the coolant contained in said additional first chamber and the simultaneous compression of coolant contained in said first chamber by said piston.
