Claims

[Claims for Utility Model Registration] A motor 9 is fitted and fixed to the cylindrical wall portion 3a of a frame 3 installed in a casing 1 serving as a low-pressure dome, and is installed concentrically with this cylindrical wall portion 3a and at the center of the frame 3. The motor rotor shaft section 10 is rotatably supported by a bearing section 12 and is connected to each piston 20 of a plurality of gas compression cylinders 18, 19... provided in the frame 3. The motor 9 and the gas compression engine IJ7 are connected by a shaft consisting of a multiple crankshaft section 13.
DalB. 19..., while opening two grooves 22 and 23 partitioned by a partition wall 24 around the bearing part 12 and in the finished surface 3b of the frame 3 perpendicular to the axis 10, thereby forming the frame. 3, and a suction shielding plate 30 which surrounds the bearing part 12 and is press-fitted into the cylindrical wall part 3a is joined to the finished surface 3b, thereby forming one groove 22 into a first suction chamber. 22, the other groove 23 is formed in the second suction chamber 23, and the first suction chamber 22 communicates with the inside of the casing 1, and the gas compression cylinders 18 are divided into two groups.
．． The second suction chamber 23 also communicates with each suction port of the first group of gas compression cylinders 18 among the gas compression cylinders 19 .
is connected to the first suction chamber 22 via an unloading valve 33 that closes during unloading, and is also connected to each suction port of the second group of gas compression cylinders 19... In the capacity-controllable multi-cylinder fully closed compressor of this type, the suction shielding plate 30 has a peripheral edge that is in pressure contact with the inner surface of the cylindrical wall portion 3a of the frame 3, so that one plate The cylindrical wall portion is a plate formed with a tapered surface that intersects at an acute angle on one surface and at an obtuse angle on the other plate surface, and the plate surface that intersects the peripheral edge at an obtuse angle is in contact with the finished surface 3b. A multi-cylinder fully closed compressor characterized in that the compressor is press-fitted into the compressor.
