Refrigerant control valve device

A refrigerant control valve device comprising:

• a spherical rotor having an opening opened in a direction of a rotation axis, and configured to rotate about the rotation axis;
• a housing which includes at least one circumferential port configured to be formed around an axis passing through a spherical center of the rotor, and an axial port formed at a side of the opening in the direction of the rotation axis, the housing being configured to allow a refrigerant to flow therein and the rotor being accommodated in the housing;
• at least one hole formed in the rotor and configured to allow the internal space of the rotor and the circumferential port to communicate with each other when the rotor rotates;
• a ring-shaped seal member installed coaxially with the circumferential port, and accommodated in the housing to be abutted on an outer surface of the rotor;
• a biasing member configured to apply a biasing force to the seal member in a direction toward the spherical center of the rotor;
• a packing body provided between the housing and an outer diameter portion of the seal member, and formed to be slidably abutted on the outer diameter portion of the seal member;
• and
• a fixing member configured to hold the packing body with the housing in a direction in which the circumferential port extends,
• wherein the seal member includes a first pressure receiving surface configured to receive a pressure applied from the refrigerant in a direction identical to a biasing direction of the biasing member, and a second pressure receiving surface having an area that is substantially equal to that of the first pressure receiving surface, and configured to receive a pressure applied by the refrigerant in a direction opposite to the biasing direction with respect to the seal member, at a side of the seal member which is filled with the refrigerant when the rotor is in a state in which the internal space of the rotor and the circumferential port do not communicate with each other.
