Embodiment Construction
[0014] The type of the connecting rod-piston structure of the present invention working in the reciprocating compressor of the small refrigeration system will be described below.
[0015] As shown in Figure 1, the reciprocating compressor of the motor-compressor assembly usually installed in a closed housing includes: a base 1 on which a stator 2 of an electric motor is installed and a bearing 3 supporting a crankshaft 4 is installed The rotor 5 of the motor is mounted on the lower part of the crankshaft, and an eccentric part 6 is provided on the upper end of the crankshaft.
[0016] The base body 1 also holds a cylinder 7 inside which houses a piston 10 traveling in a direction perpendicular to the axis of the eccentric 6 .
[0017] The connection between the piston 10 and the crankshaft 4 is achieved by articulated connection to the piston 10 of a connecting rod 20 with a rod 21 having an end 22 , the other end of which is mounted to the eccentric 6 , for example in a conve...
