Embodiment
Compressor (1) includes housing (2), and housing (2) is supported on component therein, and places the movable structure of lubrication wherein
The oil of part, motor (3), it carries rotor and stator, piston (4), and it is by using mobile from the actuating that motor (3) is received
Suck and pump out refrigerant, bent axle (5), it causes the rotary motion of rotor to pass to piston (4) in the form of linear movement, and
At least one axle journal (11), bent axle (5) is connected to piston (4) (Fig. 1) by it.
The hermetic compressor of the present invention includes at least one depression (9), and depression is located on bent axle (5), and relative to
The rotation axis of bent axle (5) is maintained at the same side with axle journal (11).In perpendicular, whole depression (9) and axle journal (11) position
In the same side.Depression (9) is using the method formation such as milling, brill on bent axle (5).Depression (9) is formed in the form of otch
On bent axle (5).By the volume of the reduction of bent axle (5), the weight of the bent axle (5) on the direction of axle journal (11) is also reduced.
