摘要： A miniaturized cost-saving intermittent short circuit determining device located between a power source and an electric load in a vehicle electric circuit. The determining device includes detecting means for detecting current flowing through the electric circuit, determining means for determining whether the current detected by the detecting means is an intermittent short circuit, and disconnecting means for disconnecting the electric circuit when the determining means judges that there is an abnormality. The determining means is connected to an external switch circuit, which selectively supplies and stops current to the electric load of the electric circuit. The determining means determines whether the external switch circuit is switched on or off, and switches the disconnecting means on or off according to the determination.

摘要： A four-way change-over valve for an air conditioner has first to fourth piping holes sequentially arranged on a concentric circle at a predetermined pitch in a planar portion of a valve seat formed in a thick disk shape as one portion of a valve case. The change-over valve also has a rotary valve rotatably arranged on an upper face of this valve seat and having at least one communicating groove for independently connecting two adjacent piping holes of the four piping holes to each other. Cooling and heating operations of the air conditioner are switched by rotating the rotary valve. A service valve with a four-way change-over valve for an air conditioner is characterized in that both service valves on liquid and gas sides of a refrigerant circuit are integrated with each other and are further integrated with the four-way change-over valve as one valve unit with one valve seat as a common valve seat. In accordance with such valve structures, the four-way change-over valve has a simplified structure and is made compact. Further, the service valve is also made compact and operability of the service valve is improved.
