Abstract:
A valve control device includes a valve unit disposed in a cooling water circuit, and a control part which controls operation of the valve unit. The control part has a rotation angle instruction part, a duty ratio calculator and a determiner. The rotation angle instruction part calculates an instruction value of a rotation angle in response to an operational status of an internal-combustion engine. The duty ratio calculator calculates a duty ratio representing a ratio of ON period to OFF period regarding a voltage applied to an electric motor based on a difference between a detection value of the rotation angle detected by a detector and the instruction value of the rotation angle, and regulates the duty ratio to be lower than or equal to a predetermined upper limit. The determiner determines whether the duty ratio continues to be the upper limit during a predetermined period.

Claim (Index 1):
A valve control device for a cooling water circuit through which cooling water of an internal-combustion engine circulates to a radiator, and a heater core, the valve control device comprising:\n a valve unit disposed in the cooling water circuit to increase or decrease a flow rate of cooling water to the internal-combustion engine and to start or stop circulation of cooling water to the radiator and the heater core; and a control part which controls operation of the valve unit, wherein the valve unit has\n a valve object, and \n a housing that houses the valve object, \n the housing has\n a first passage defined in the housing to communicate with a first channel connected to the heater core, and a first opening defined at an inner circumference side of the first passage, \n a second passage defined in the housing to communicate with a second channel bypassing the heater core and the radiator, and a second opening defined at an inner circumference side of the second passage, and \n a third passage defined in the housing to communicate with a third channel connected to the radiator, and a third opening defined at an inner circumference side of the third passage, \n the valve object has a plurality of valve holes passing through in a radial direction, and is configured to rotate to start or stop circulation of the cooling water to the first passage, the second passage or the third passage, and when the first opening and one of the valve holes fully overlap with each other, the valve object rotates to cause an overlap ratio between the second opening and another one of the valve holes and an overlap ratio between the third opening and another one of the valve holes to be in inverse proportion.
