Valve device

A valve device for controlling a coolant used in an automobile, the valve device comprising:

• a valve member that includes
• a shaft portion rotatable about a rotation axis, and
• a rotor connected to an end of the shaft portion, wherein the end of the shaft portion is an end in a first direction along the rotation axis, and wherein on an outer circumferential surface of the rotor there is a first flow path with a first opening;
• a housing that includes
• an accommodating portion for accommodating the valve member, and
• a second flow path having a second opening communicable with the first opening, the accommodating portion having on its inner circumferential surface the second opening;
• a first seal disposed between an outer circumferential surface of the rotor and an inner circumferential surface of the accommodating portion, wherein the first seal includes a first portion that is located in the first direction relative to the second opening and a second portion that is located in a second direction opposite to the first direction relative to the second opening;
• and
• a second seal that is located in the second direction relative to the second portion, and is disposed between an outer circumferential surface of the valve member and an inner circumferential surface of the accommodating portion,
• wherein the valve member has a communication path that communicates a first space with the first flow path, wherein the first space is surrounded by the outer peripheral surface of the valve member, the inner peripheral surface of the accommodating portion, the second portion, and the second seal.
