    Abstract: A water pump (1) according to the present invention comprises an electromagnetic clutch (60) that switches between a transmission state where a pump pulley (20) and an armature (83) of an armature assy (80) are made to frictionally engage to transmit drive force of the pump pulley (20) to a pump shaft (30) and a cutoff state where frictional engagement of the pump pulley (20) and the armature (83) of the armature assy (80) is released to cut off transmission of drive force from the pump pulley (20) to the pump shaft (30), and a flange member (120) provided on the armature assy (80) to rotate integrally with the pump shaft (30) and is configured such that when in the cutoff state, by magnetic attractive force between a permanent magnet (111) of the pump pulley (20) and a permanent magnet (131) of the flange member (120), the flange member (120) is rotated together with the rotation of the pump pulley (20).

    Abstract: A control device for a dutch, which is provided between an operating machine and a drive shaft of an engine, controls the operation of a valve member for opening and closing an oil supply hole through which an oil reservoir chamber and a torque transmission chamber communicate. The control device refers to a target rotational speed of a rotational solid of the operating machine and to the acquired rotational speed of the rotational solid of the operating machine, calculates a proportional manipulated variable based on the deviation between the angular acceleration of the rotational solid and a target angular acceleration, and controls the operation of the valve member on the basis of this calculated proportional manipulated variable.

    Abstract: A coolant control valve unit includes a wall including a passage disposed at a predetermined position from one surface to another surface, a valve disposed to be inserted into the passage and open and close the passage according to a movement position, and an actuator opening and closing the passage through the valve by pushing or pulling the valve by using a stem connected with the valve, wherein one side and another side of the wall are formed to have a height difference in a movement direction or in an opposite movement direction so that a portion of the passage is opened and a remaining part of the passage is closed by the valve when the valve moves along the passage.

    Abstract: A clutch device for a clutch system has an input member that rotates at a first speed. A friction drive system is disposed between the input member and an output member. The clutch device is selectively movable by a fluid actuator assembly, between an engaged position in which the friction drive system drives the output member to rotate at the first speed, and a disengaged position in which a viscous drive system rotates the output member at a second speed slower than the first speed. A variable viscous fluid supply assembly includes a viscous fluid storage chamber, a valve, and a valve actuator that selectively drives the valve to move between an open position and a closed position to control an amount of viscous fluid available to the viscous drive system, thereby varying the second speed.

    Abstract: An engine cooling fan control strategy includes measuring an engine coolant temperature using a sensor connected to the engine, measuring an engine oil temperature using a sensor connected to the engine, selecting a first value from a maximum engine coolant temperature threshold calibration curve stored in the control system based on the engine oil temperature, selecting a second value from a minimum engine coolant temperature threshold calibration curve stored in the control system based on the engine oil temperature, and placing the engine cooling fan in driven relationship with the engine when the engine coolant temperature exceeds the first value, and placing the engine cooling fan in non-driven relationship with the engine when the engine coolant temperature drops below the second value.
