Document Type and Number:
WIPO Patent Application WO/2015/096850
Kind Code:
A1
Abstract:
Crankshaft (1) for a reciprocating compressor (2) of a refrigeration appliance, wherein the reciprocating compressor (2) has a variable refrigeration capacity, the crankshaft (1) comprising a shaft (3) which is integrally provided with an overhang portion (4), a pin (5) for pivotably attaching a connecting rod (6) which is coupled to a piston head (7), wherein the pin (5) is formed on the overhang portion (4) eccentrically with respect to a rotation axis (Ax) of the shaft (3) and a main counterweight (8) which is formed by the overhang portion (4), wherein a center-of-mass of the main counterweight (8) is radially opposed to the pin (5) and radially offset from the rotation axis (Ax). A retainer is formed on the main counterweight (8) and an additional counterweight (9) which is slidably seated into the retainer (25) so as to radially move outwards or inwards respectively between an outer position and an inner position, wherein the additional counterweight (9) is resiliently biased towards a rest position.
