The present invention relates to a freezing cycle apparatus. More specifically, the present invention relates to a freezing cycle apparatus having a pulsation reduction function which includes a multi-step pressure chamber and a choke to reduce pulsation discharge caused by pressure disequilibrium and noise due to the pulsation discharge when compressing a refrigerant using a single cylinder reciprocating piston-type compressor. The freezing cycle apparatus includes a compressor, a condenser, a capillary tube, and an evaporator. The freezing cycle apparatus having a pulsation reduction function includes a reciprocating piston-type compressor to compress a refrigerant; a refrigerant storage device to store and supply the refrigerant; a first refrigerant flow channel connecting the compressor to the refrigerant storage device; a second refrigerant flow channel connected to the first refrigerant flow channel at a first connection point and a second connection point; a suction valve formed on the first refrigerant flow channel between the first connection point and the second connection point; a first choke, a first pressure chamber, a second choke, a second pressure chamber, a third choke, a third pressure chamber, and a delivery valve sequentially formed on the second refrigerant flow channel between the first connection point and the second connection point; a fourth chamber formed on the first refrigerant flow channel between the compressor and the second connection point; and a condenser, a capillary tube, and an evaporator connected to the first refrigerant flow channel.
