Reference numeral 11 in the figure is the frame, and a cylinder member 12 is integrally formed on this frame 11 by a manufacturing method described later. Further, a suction side muffler 15 and a discharge side muffler 16 are integrally cast into the left and right wall portions 13 and 14 of the cylinder member 12 separately. In other words,
Hollow object 1 consisting of a short cylindrical body with both ends closed
7, 17, 18, 18, and the hollow 1
By drilling holes 19 and 20 through holes 7, 17, 18, and 18, each muffler 15, 16
That is. Further, each muffler 15, 16 communicates with a cylinder chamber 23 via a valve cover 21 and a valve plate 22.
24 is a piston, and 25 is a driving head thereof. The driving head 25 is connected to a rotating shaft (not shown) of a motor supported in a shaft hole 26 formed in the frame 11.

As explained above, according to the present invention, it is possible to easily and accurately manufacture an integrated cylinder and muffler. Moreover, since the muffler can be formed without using brazing, bolts, etc., a highly accurate and reliable muffler can be obtained at low cost, and productivity can be improved. Furthermore, since the muffler chamber is completely sealed, a noise reduction effect is ensured, and no sound leaks. In addition, when casting the cylinder member of a compressor, the muffler is formed by the internal space of the hollow material buried within the casting.
The hollow material buried within the casting provides an exceptional effect of improving the strength of the structure.
