(57) Abstract:
Dual capacity compressor including a power generating part (20)
having a reversible motor (21, 22) and a crank shaft (23) inserted in
the motor (21, 23), a compression part (30) having a cylinder (32), a
piston (31), and a connecting rod (33), a crank pin (110) in an upper
part of the crank shaft (23) eccentric to an axis of the crank shaft, an
eccentric sleeve (120) rotatably fitted to the crank pin (110), and the
connecting rod (33) respectively, a key member (130) for positive
fastening of the eccentric sleeve (120) to the crank pin (110) in all
rotation directions of the motor, and an eccentric mass (200) provided
to the eccentric sleeve (120) for rotating the eccentric sleeve (120)
around the crank pin (110), thereby preventing relative motion
between components that sustain the eccentricity, and permitting a
smooth motion between the components.
