Abstract (en)

[origin: WO2016092514A1] Reciprocating compressor (100) for a cooling device (200) provided with a closed circuit (C) having a main branch (M), in which a first flow rate (X) of circulating coolant enters in said compressor, and at least one first economizer branch, or secondary branch (E), in which a second flow rate (XI) of coolant circulates under a pressure different from the pressure of said first flow rate (X) of coolant, said compressor being provided with at least one cylinder (110) and at least one piston (111) reciprocatingly moving in said at least one cylinder, between a top dead centre (S) and a bottom dead centre (I), and comprising at least one suction duct for the entrance of said first flow rate of coolant, and at least one port (107) obtained in the wall of said cylinder for the entrance of said second flow rate of coolant, in such a way that said piston exposes at least in part said at least one first inlet port (107), at least during its inlet stroke, and covers said at least one port at least during its compression stroke, characterized in that said at least one first inlet port (107) has a slit shape with the main dimension substantially transverse to the axis (A) of said cylinder.
