Abstract

PURPOSE:To remove the stagnation of refrigerant near a retaining ring by preparing a ventilation spacer having an inclined plane along the flow of refrigerant and a ventilation hole between the endcoils with an inserted intercoil spacer. CONSTITUTION:Between the endcoils 1 with an inserted intercoil spacer 5 a ventilation spacer 6 having an inclined plane along the flow of the refrigerant when rotating as well as a ventilation hole thereon is to be inserted. Thereby the refrigerant is forced to flow thus to improve a refrigerating effect of the endcoil with an increased quantity of refrigerant.
