摘要:
A hydrodynamic coupling device is provided including a housing, a lock up clutch, a friction surface mechanism, a fluid duct and three connecting ducts. The lock up clutch has a clutch element arranged in the housing and may be pressed against the housing. The friction surface mechanism is arranged between the clutch element and the housing. The clutch element and the friction surface mechanism separate an interior of the hydrodynamic coupling device into a first fluid space and a second fluid space. The fluid duct means is in the friction surface mechanism and permits the working fluid to flow into and out of the first fluid space while preventing the working fluid from flowing out of the first fluid space into the second fluid space. The connecting ducts are in the fluid duct, with the first connecting duct is capable of permitting flow of the working fluid to the first fluid space, the second connecting duct is capable of permitting flow of the working fluid into and out of the second fluid space. The third connecting duct is capable of circulating the working fluid within the first fluid space before permitting the working fluid to flow out of the first fluid space, at least when the clutch element is pressed up to the housing with the friction surface arrangement interposed between them.
