To provide a reciprocating type compressor of a refrigerating circuit capable of reducing a heat load, while easily realizing high pressure of a delivery refrigerant.

This reciprocating type compressor of the refrigerating circuit has a plurality of compression cells arranged in a housing 16 and having a cylinder bore 30 and a piston 32, an intermediate chamber 66 connecting respective groups in a cascade shape in two stages by classifying the compression cells into two groups, and an introducing port 76 introducing the refrigerant of a gaseous phase from a gas-liquid separator in the refrigerating circuit to the intermediate chamber 66.
