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 9):
A valve control device comprising:\n a valve unit disposed in a cooling water circuit to increase or decrease a flow rate of cooling water to an internal-combustion engine and to start or stop circulation of cooling water to a radiator and a heater core, wherein the valve unit having\n a valve object and \n a housing that houses the valve object, \n the housing has\n a heater passage to communicate with the heater core, \n a bypass passage to communicate with a channel bypassing the heater core and the radiator, and \n a radiator passage to communicate with the radiator, \n the valve object is configured to rotate to start or stop circulation of the cooling water to the heater passage, the bypass passage and the radiator passage, and the valve object is configured to change an open degree of the bypass opening and an open degree of the radiator passage to be in inverse proportion in a state where the heater passage is fully opened by the valve object.
