摘要： A fluid brake device has a case defining a fluid chamber. Magneto-rheological fluid is contained in the fluid chamber. A brake member is rotatably supported on the case and receives a braking torque according to the viscosity of the magneto-rheological fluid. The device has a movable member driven by a thermo-sensitive wax so that a volume of the fluid chamber is increased as the temperature in the fluid chamber is increased. The movable member is driven to maintain a pressure in the fluid chamber within an allowable range when the temperature in the fluid chamber is changed.

摘要： A fluid brake device has a brake shaft which penetrates a case. The case provides a fluid chamber for a magneto-rheological fluid. A magnetic seal has a magnetic seal sleeve which holds a small amount of the magneto-rheological fluid by magnetic flux. In addition to the magnetic seal, an axially pumping element is provided on an axial outside of the magnetic seal. The axially pumping element is provided by a shaft helical groove formed on an opposing wall of the brake shaft and/or a case helical groove formed on a surrounding wall. As the brake shaft rotates, the helical groove pushes the magneto-rheological fluid back to the magnetic seal. A combination of the magnetic seal and the axially pumping element may reduce leakage of the magneto-rheological fluid.

摘要： A phase adjusting mechanism is engaged with a brake shaft, and adjusts a rotation phase between a crankshaft and a camshaft according to a braking torque acting on a rotor. The rotation phase is adjusted in a predetermined direction when the braking torque is increased. A torque input mechanism inputs a return torque into the phase adjusting mechanism to return the rotation phase in an opposite direction opposite from the predetermined direction. The torque input mechanism increases the return torque corresponding to the rotation phase as an environmental temperature of the variable valve timing apparatus is lowered.

摘要： A valve timing controller has a case which defines a fluid chamber therein. A magnetic viscosity fluid is enclosed in the fluid chamber. The magnetic viscosity fluid including magnetic particles and its viscosity varies according to a magnetic field applied thereto. A coil and a control circuit applies magnetic field to the magnetic viscosity fluid to variably control a viscosity thereof. A brake rotor is rotatably accommodated in the fluid chamber and receives a brake torque from the magnetic viscosity fluid according to the viscosity thereof. A phase adjusting mechanism is connected to the brake rotor for adjusting a relative rotational phase between the crankshaft and the camshaft according to the brake torque. When it is estimated that the engine will be started, the coil is energized to generated heat in the magnetic viscosity fluid.
