摘要： A viscous fluid coupling device comprises a housing; a partition board dividing an internal space in the housing into a storage chamber and an operation chamber, the partition board having first communicating holes to communicate the storage chamber with the operation chamber; a rotor which is provided in the operation chamber and is secured to one end portion of a drive shaft so as to rotate together with the drive shaft; a valve provided in the storage chamber to open and close the first communicating holes; and a rod having one end secured to the valve and the other end secured to the inner peripheral portion of a spiral bimetal. The rod is rotatably supported by the housing and the housing and the rotor have labyrinth grooves in the surfaces which are confronted with each other. The viscous fluid coupling device further comprises a second communicating hole which is located radially inwardly of the labyrinth grooves to discharge the viscous fluid from the operation chamber into an internal space of the operation chamber when the viscous fluid is raised high in temperature; and a temperature responding member connected to a seal member to open and close the second communicating hole.

摘要： A viscous fluid coupling has a rotor including peripheral teeth with distal ends closely facing an inside surface of an output member. The distal ends of the teeth form flat surfaces parallel with the output member to form a rotary seal therewith, which reduces variations in the rotational speed of the output member.

摘要： A viscous fluid coupling device includes a drive shaft, a housing rotatably supported by the drive shaft, a partition wall dividing an interior space of the housing into an operation chamber and a storage chamber having a circular arc portion, a rotor accommodated in the operation chamber and fixed to the drive shaft, a supply passage for supplying operating fluid from the storage chamber to the operation chamber, a return passage for returning the operating fluid in the operation chamber to the storage chamber, and a first valve disposed in the supply passage and the return passage respectively. The first valve is closed when the drive shaft rotates at a speed lower than a predetermined rotation speed and opened when the drive shaft rotates at the predetermined rotation speed. The viscous coupling device further includes an opening of the supply passage and a second valve for opening and closing the opening.

摘要： An externally-controlled fluid coupling includes a driving disk fixed to a driving rotational shaft, a case member and a cover member rotatably supported by the rotational shaft, a separating plate for forming an operation chamber and a storage chamber between the case member and the cover member, a supply passage for supplying the fluid to the operation chamber, a return passage for returning the fluid to the storage chamber, a supply/return valve for opening or closing the supply/return passage and an electromagnetic actuating apparatus including an electromagnet for actuating the supply/return valves. The electromagnet generates a first power of magnetism for actuating the supply valve and a second power of magnetism for actuating the return valve. The values of the first and second powers of magnetism are different from each other so that the supply valve and the return valve open/close nonsynchronously.
