Abstract: An actuator includes a rod, an electric motor to generate a rotational driving force on supply of electricity, an output shaft to output the rotational driving force of the electric motor to the rod, a feed screw mechanism, and a rotation prevention mechanism. The feed screw mechanism includes a female screw portion formed on one of the output shaft and the rod, and a male screw portion formed on the other to mesh with the female screw portion. The rotation prevention mechanism is configured to regulate rotation of the rod caused by the rotational driving force of the electric motor.

Abstract: In a heat pump cycle device, a flow passage switching portion includes a flow passage switching valve body configured to open and close a cooling side flow passage. A refrigerant circulation circuit includes a low-pressure flow passage through which a low-pressure refrigerant decompressed by a first decompressor flows toward a compressor in a heating mode, and a pre-evaporator flow passage provided between the flow passage switching valve body and a refrigerant inlet of an evaporator. The flow passage switching portion causes a pre-evaporator flow passage to communicate with the low-pressure flow passage while bypassing the evaporator when a refrigerant pressure in the low-pressure flow passage is lower than a refrigerant pressure in the pre-evaporator flow passage, in the heating mode.

Abstract: An integrated valve includes a body portion, a flow rate adjustment valve body, a flow passage switching valve body, and a shaft member. The body portion has formed therein a plurality of passages. The flow rate adjustment valve body is provided inside the body portion that adjusts a flow rate of fluid. The flow passage switching valve body is provided inside the body portion configured to switch a flow path of the predetermined fluid in the fluid circulation circuit, the flow passage switching valve body being switchable between distinct communication states. The shaft member is provided inside the body portion that interlocks the flow rate adjustment valve body and the flow passage switching valve body.
