ROTARY ELECTRIC COMPRESSOR OF CLOSE VERTICAL TYPE

摘要

PURPOSE:To prevent the occurrence of a fall impact sound by providing an ever-compressed elongation spring between the lower part of a delivery pipe and the upper end of a crank-shaft. CONSTITUTION:The upper end of a crank-shaft 4 is projected upward from a rotor 3 and the lower part of an elongation spring 13 is made in contact with the top of the projected crank-shaft and the upper part of the said spring 13 is hooked to the lower end of a delivery pipe 12 for a refrigerant gas. And, the elongation spring 13 is so set as to be ever-compressed between the upper end of the crank-shaft 4 and the lower part of the delivery pipe 12. By this arrangement, the rotor 3 is not pushed upward by a refrigerant gas delivered from a muffler and it is possible to prevent the occurrence of a fall impact sound due to the lateral force of an electric motor and the weight of the rotor 3 and the crank-shaft 4.
