Electrically operated valve

An electrically operated valve comprising:

• a valve main body which has a first valve chamber and a second valve chamber in an inner part thereof;
• a first valve body which has a first valve body inner space in an inner part thereof and switches a flow passage for fluid by being rotationally driven within the first valve chamber;
• a second valve body which has a second valve body inner space in an inner part thereof and switches a flow passage for fluid by being rotationally driven within the second valve chamber;
• and
• a transmission mechanism which transmits a drive force for rotating the first valve body and the second valve body to the first valve body and the second valve body,
• wherein the valve main body comprises:
• a first flow passage hole which allows a communication state with the first valve body inner space to be changed by a rotational displacement position of the first valve body, and communicates with the first valve body inner space at a first rotational displacement position of the first valve body;
• a second flow passage hole which allows a communication state with the first valve body inner space to be changed by the rotational displacement position of the first valve body, and communicates with the first valve body inner space at a second rotational displacement position of the first valve body;
• a communication flow passage which communicates with the first valve body inner space, allows a communication state with the second valve body inner space to be changed by a rotational displacement position of the second valve body, communicates with the second valve body inner space at each of the first rotational displacement position and the second rotational displacement position of the second valve body, and allows the fluid to pass through between the first valve body inner space and the second valve body inner space;
• a third flow passage hole which allows a communication state with the second valve body inner space to be changed by the rotational displacement position of the second valve body, and communicates with the second valve body inner space at a third rotational displacement position of the second valve body;
• and
• a fourth flow passage hole which communicates with the second valve body inner space.
