Document Type and Number:
Japanese Patent JP6380073
Kind Code:
B2
Abstract:
Provided is a refrigerant control valve apparatus configured such that a contact pressure of a seal body relative to a valve body does not fluctuate. The valve body is accommodated inside a valve housing 10 so as to be rotatable about a rotational axis, the valve housing 10 being formed with an inlet port and a discharge port, and a seal mechanism is provided between the discharge port and a valve surface of the valve body. The seal mechanism includes a seal body and a biasing mechanism. The seal mechanism is provided with a first pressure receiving surface receiving pressure of the refrigerant, which acts in a direction same as a biasing direction of the biasing mechanism, and a second pressure receiving surface receiving pressure of the refrigerant, which acts in a direction opposite to the biasing direction of the biasing mechanism. The first pressure receiving surface and the second first pressure receiving surface are formed to include an equal area to each other, and the seal mechanism is accommodated within a seal accommodation space such that pressure of the refrigerant from the inlet port acts on the first pressure receiving surface and the second pressure receiving surface.
