COMPRESSOR FOR A REFRIGERATING PLANT AND REFRIGERATING PLANT COMPRISING SAID COMPRESSOR

摘要

A compressor for a refrigerating plant comprising at least one cylinder (12); at least one piston (13), which slides alternately inside the cylinder (12); at least one head (18a) provided with a suction chamber (19), connected to a suction line (9) of the plant (1) and to the cylinder (12) to supply the cylinder (12) with a refrigerating fluid, and with a suction valve (25a), configured to regulate the flow rate of refrigerating fluid; the suction valve (25a) is movable between a first position, wherein is defined a first flow area which allows the suction of a first flow rate of refrigerating fluid, and a second position wherein is defined a second flow area smaller than the first flow area which allows the suction of a second flow rate of refrigerating fluid lower than the first flow rate.
