Hermetic compressor

An object of the present invention is to provide a multi-cylinder rotary compressor which can eliminate a number of balancers for preventing vibrations. Assuming that the mass eccentricity in a cylinder is m1 x r1; the mass eccentricity in another cylinder is m2 x r2; the mass eccentricity of a bala...

More Information
Summary:An object of the present invention is to provide a multi-cylinder rotary compressor which can eliminate a number of balancers for preventing vibrations. Assuming that the mass eccentricity in a cylinder is m1 x r1; the mass eccentricity in another cylinder is m2 x r2; the mass eccentricity of a balancer attached to the lower side of a rotator is m3 x r3; the mass eccentricity of another balancer attached to the upper side of the rotator is m4 x r4; respective distances from the cylinder to another cylinder, the lower balancer and another balancer are L2, L3 and L4, when the balancing is attained with the expressions m1 x r1 + m4 x r4 = m2 x r2 + m3 x r3, m4 x r4 x L4 = m2 x r2 x L2 + m3 x r3 x L3, and m1 x r1 = m2 x r2, the lower balancer is eliminated and the mass eccentricity of the balancer is set to be not less than 20% and not more than 80% of m4 x r4.
