復動型圧縮機における騒音低減構造。 Multiple pairs of cylinder bores are drilled parallel to the rotation axis in the cylinder block, facing each other on the front and rear sides, with a cam chamber in between, and a double-headed piston is installed in each cylinder bore. A mooring recess is provided at the rear of the double-headed piston, and a roller is moored in the mooring recess, while a disk cam curved in the shape of a corrugated plate is installed in the cam chamber. The shaft is rotatably mounted on the rotating shaft with a small gap between the shaft and the shaft, and
In a disc cam type reciprocating compressor in which a double-headed piston is provided so as to be able to reciprocate via the same disc cam,
A first engaging portion and a second engaging portion having a smaller diameter are provided opposite to each other on the roller and the mooring recess so as to correspond to the center of rotation of the roller, and the first engaging portion and the second engaging portion are provided oppositely to each other. The roller is provided to freely rotate with a certain amount of play with respect to its center of rotation through engagement with the disc cam, and the play of the roller is provided to be smaller than the minute gap formed between the roller and the disk cam. A noise reduction structure for a disc cam type reciprocating compressor.
