Abstract
A refrigerant suction guide structure of a reciprocating compressor is provided. The refrigerant suction guide structure includes a cylinder having an accommodating space inside, a piston having suction channels through which refrigerant is inhaled inside and inserted into the cylinder to be in a linear reciprocating motion, a suction valve included in the end of the piston to open and close the suction channels, and a valve fixing member for combining the suction valve with the piston. The suction channels of the piston include inclined surfaces for guiding refrigerant to the outside in which the suction valve is first opened. The suction channels are formed so as to be inclined to reduce flow resistance of inhaled refrigerant such that the amount of the inhaled refrigerant is increased. Therefore, it is possible to improve the efficiency of a compressor.
