装置からなる。2. Description of the Related Art Conventionally, a rotary type refrigerant switching device for an air conditioner which is also used for cooling and heating has been disclosed in Japanese Utility Model Laid-Open No. 3-5757.
The device of Japanese Patent No. 1 is known. It is a motor that is a drive source for rotating the valve body and is integrally fixed to a casing that forms a valve chamber that houses the valve body through a gas seal plate, and the output shaft of the motor and the input shaft of the valve body. Each of the drive side magnet and the driven side magnet is attached to and configured so that the rotational movement of the motor can be transmitted to the valve body by the action of both magnets through the gas seal plate shielded between them. Cylindrical valve chamber having four conduits that can be connected to the circuits for sending and suction that are connected to the heat exchanger and the cooling system, respectively, is provided with elasticity that divides the valve chamber into two in the axial direction of the valve chamber. Both sides of the valve body are rotatably slidably mounted on the inner wall of the valve chamber, and when the fluids of different pressures flow through the two formed flow passages, the pressure of the high pressure side moves the valve body to the low pressure side. Press the valve body and valve Rotation in an air conditioner for both air-conditioning and heating, characterized in that the inner wall can be pressed tightly and the flow direction of the fluid can be switched to four flow passages by a rotational motion given to the valve body from the outside. Type refrigerant switching valve device.
