且つ軽量の圧縮機を提供することを目的とする。A cylinder 2 and a piston 3 are arranged on the upper part of the frame, and an electric motor 4 is arranged below the frame. The rotational movement of the electric motor is transmitted to the crankshaft pin part 6 through the crankshaft 5 inserted into the bearing part of the frame.
and a slider 7 that slides in a cross-shape with the reciprocating direction of the piston 3, and a sliding tube 8 that is integrally joined to the piston 3.
This is converted into a reciprocating motion of the piston 3 through this process. These compressor bodies are connected to a closed container 1 by hanging springs 9, etc.
It is elastically suspended and supported at 0. Suction and exhaust silencer 1
1 and 12 are cast integrally with the cylinder 2 so as to fit into the cylinder bore 13, and an intake pipe 14 and an exhaust saddle pipe 15 are connected to the ends thereof. The silencer partition wall is provided with holes 16 through which intake and exhaust gases flow, and furthermore, as shown in FIG. It is something that allows you to demonstrate your abilities. The valve seat cover 19 is also formed by casting and is fixed to the top of the cylinder via the valve 22 and valve seat 23. A suction chamber 20 and a discharge chamber 21 are provided on the surface of the valve seat cover 19 that is joined to the valve 22. Silencers 11, 12 and valve seat cover 19 of such a compressor
Since they are manufactured by casting, precision is required in the shaping and combination of the cores, and they also require considerable wall thickness, which is an obstacle to making them lighter and smaller. Also, it requires machining,
Particularly, the machining of this type of cylinder requires complicated three-dimensional processes, has poor productivity, and is contrary to resource conservation because it involves removal machining. [Object of the Invention] The present invention has been made in view of the above points, and an object of the present invention is to provide a compact and lightweight compressor.

合部を銅ろう付して固着封室する。The intake silencer 11 is constructed by layering an appropriate number of members formed by drawing a steel plate. This intake silencer 11 has an intake pipe 14 made of an iron pipe connected to one end thereof, and a protruding closing portion 25 formed by burring at the end thereof. The exhaust silencer 12 is constructed by laminating several drawing-formed steel plates. This exhaust silencer 12 has a discharge support pipe 15 made of an iron pipe connected to one end, and a protruding closing portion 25 formed with burring at the other end. On the other hand, the valve seat cover 19
is constructed by joining a substrate 19a and an external force bar 19b.
The substrate 19a is manufactured by punching a steel plate and punching gas circulation holes 24 therein. Further, the external force bar 19b is manufactured by drawing a steel plate. By joining the substrate 19a and the external force bar 19b, an intake chamber 20 and an exhaust chamber 21, which pass through the gas circulation hole 24, are formed. Then,
The protrusions 25 of the intake silencer 11 and the exhaust silencer 12 are combined so as to protrude in the same direction into the gas flow holes 24 formed on both sides of the substrate 19a, and the joints of each member are copper soldered to securely seal them. room.
