An engine cooling system compromises a main channel connecting an engine and a radiator, and a coolant control valve apparatus controlling a flow rate of coolant water in the main channel having a main rotary valve. The main valve includes a rotor and a casing that has an inner peripheral surface facing an outer peripheral surface of this rotor, and a gap is provided between the outer peripheral surface of the rotor and the inner peripheral surface of the casing. The inner peripheral surface of the casing has a main opening part that is connected to the main channel, and this main opening part is provided with a sealing member that protrudes to the outer peripheral surface of the rotor. This sealing member composes a channel that connects an opening part of the rotor and an opening part of the casing.

Coolant control valve apparatus

A rotary valve that includes a rotor and a casing which rotatably accommodates the rotor. The casing includes an inflow side opening through which a fluid flows in from the outside to the rotor accommodating space and two outflow side openings through which the fluid flows out from the rotor accommodating space to the outside, at a position opposite to an outer circumferential surface of the rotor. The rotor is formed in a cylindrical shape having an internal space. An end surface of the rotor is provided with an end surface side opening which communicates with the internal space. The outer circumferential surface of the rotor is provided with a rotor outer circumferential opening and a rotor outer circumferential blocking surface which are configured to open and close the outflow side openings of the casing.

Rotary valve

A cooling water control valve apparatus capable of independently controlling flow rates of cooling water in two lines with a single apparatus for cooling water control and capable of achieving cost reduction. A cooling water control valve apparatus which adjusts a flow rate of cooling water for cooling an object to be cooled includes two inlet ports through which cooling water is introduced, an electrical control valve which is arranged at a first passage communicated with one of the inlet ports and which adjusts a flow rate of cooling water flowing through the first passage with electronic control, and a thermosensitive valve which is arranged at a second passage communicated with the other of inlet ports and which adjusts a flow rate of cooing water flowing through the second passage owing to displacement of a temperature detecting medium with temperature.

Cooling water control valve apparatus

A coolant control valve apparatusincludes a main valvewhich adjusts a flow rate of a coolant in a main channelto control the flow rate of the coolant in the main channel. Further, the coolant control valve apparatusincludes a detour channelprovided being diverged from the main channelso as to detour the main valve. The coolant control valve apparatusincludes a valve main bodywhich opens and closes the detour channeland a temperature detection mediumwhich can open and close the valve main bodyaccording to a temperature of the coolant. The temperature detection mediumis disposed in the diverging part between the detour channeland the bypass channel
