摘要： PURPOSE:To enhance the corrosion resistance of the inner wall of an outlet chamber at a coolant inlet and outlet guide unit for a liquid-cooled rotor type rotary electric machine and eliminate noise thereat by so mounting an L-shaped cross sectional exhaust ring at the exhaust portion of coolant as to cover the opening of an outflowing tube and forming an exhaust hole in parallel with an axial line at the end of the ring to exhaust the coolant. CONSTITUTION:An L-shaped cross sectional exhaust ring 11 is so mounted at the exhaust portion for dicharging coolant into the outlet chamber 612 from the exhaust passage 31b of a coolant supply and exhaust tube 41 as to form a container 11c around the opening of the exhaust passage 31b. A plurality of axial exhaust holes 12 are further formed at the end face 11b of the ring 11 at the opposite side to the outer wall of the outflowing tube 31 to discharge the coolant into the outlet chamber 612. In this manner, this configuration can decelerate the speed of the coolant in radially outward direction when the coolant is discharged into the outlet chamber, eliminate the collision of the coolant with the inner wall of the outlet chamber 612, and prevent the corrosion and noise at the inner wall of the outlet chamber.

摘要： PURPOSE:To increase the sealing effect of a coolant inlet and outlet guide unit for a rotary electric machine and shorten the length of a coolant supply and exhaust tube by providing a sealing plate at the end of an outlet chamber and forming threads on the surface of the tube confronting the sealing plate so that air may flow into the outlet chamber. CONSTITUTION:An outlet chamber 63 for receiving leaked coolant is provided in the neighborhood of the outlet chamber receiving the coolant discharged from an exhaust passage of a coolant supply and exhaust tube, and a sealing plate 11 is provided at the end of the outlet chamber. Threads 10 are formed in an atmospheric air inflowing direction into the outlet chamber 63 on the outer surface of the tube 4 confronting the sealing plate 11 to form a thread seal thereon. In this manner, since the coolant to be leaked through the gap between the tube 4 and the sealing plate 11 is interrupted to leak by the air flow inflowing against the coolant, it increases its sealing effect to make it possible to shorten the length of the tube 4 upon shortening of the sealing portion so as to prevent the axial vibration of the tube.

摘要： PURPOSE:To simplify the sealing structure for preventing the leakage of cooling liquid by supplying shielding gas into an outlet chamber, providing a temperature sensing element in an exhausting pipe, and controlling the amount of the shielding gas to be supplied depending on the temperature of the cooling liquid. CONSTITUTION:Shielding gas in supplied to an outlet chamber 62 which exhausts the cooling liquid discharged from a flowing pipe 3b from a gas source 11 to the stator side via a control valve 10. A temperature sensing element 13 for the cooling liquid is provided in an exhausting pipe 71, and is connected to the control valve 10 via an actuator 12. When the temperature of the cooling liquid has risen, the amount of the gas supply is decreased; and when the temperature has decreased, the amount of the gas supply is increased; thereby the pressure in the outlet chamber 62 is compensated. In this constitution, the leakage of the cooling liquid to the outlet chamber 63 in which atmospheric air is introduced can be decreased. The sealing between the outlet chambers 62 and 63 can be sufficed by a labyrinth seal 83.
