A STRUCTURED CONTAINER FOR A SEALED MOTOR COMPRESSOR UNIT WHICH REDUCES THE TRANSMNISSION OF THE NOISE CREATED BY THE WORKING OF THE COMPRESSOR

摘要

A structured container for a sealed motor compressor unit which reduces the transmission of the noise created by the working of the compressor which comprises a housing of substantially ovoid form within which said motor compressor is located, said housing being composed of an upper concave portion and a lower concave portion each of varying radius of curvature, said portions being hermetically sealed to each other to provide said housing having in longitudinal section an asymmetrical configuration and in transverse section an elliptical configuration, characterized in that the top of said upper portion is provided with a spherical-cup-shaped depression of a predetermined depth, the centre of the circle describing said depression being offset from the centre of the ellipse seen in transverse section of said housing, the axis of rotation of motor lying along the vertical axis passing through the centre of said ellipse and hence offset from the centre of said circle describing said depression.
