Abstract

An oil feed controller of an inverter compressor controls the quantity of feeding oil to prevent excess oil from being fed to a compression part when rotational speed of a rotation shaft is increased. The oil feed controller includes an installation hole formed in the rotation shaft to communicate with an oil passage of the rotation shaft, a bypass formed in the rotation shaft to communicate with the leading end of the installation hole, and an oil feeding controlling part installed in the installation hole to close the bypass when the rotation shaft rotates at low speed and to open the bypass when the rotation shaft rotates at high speed such that the quantity of oil ascending to the compression part through the oil passage is controlled.

Description

technical field [0001] The present invention relates to an inverter compressor, and more particularly, to an oil supply control device for an inverter compressor, which prevents excessive oil supply to the inverter compressor by controlling an oil supply amount when the rotation speed of a rotating shaft increases. Background technique [0002] figure 1 is a vertical sectional view showing a conventional inverter compressor, figure 2 yes figure 1 An enlarged view of part "A" in . [0003] Such as figure 1 and figure 2 As shown, a conventional variable frequency compressor includes: a casing 100 having a suction pipe 101 and a discharge pipe 102; a main frame 200 and an auxiliary frame 300 fixed to the upper side and the lower side of the casing 100; variable frequency drive components 400, which is installed between the main frame 200 and the auxiliary frame 300; the rotating shaft 500, which is rotated by the variable frequency drive part 400; and the compression par...
