An electric compressorincludes a compression mechanism, an electric motordriving the compression mechanism, and a control portioncontrolling to drive the electric motor, incorporated into a single casing, and further includes a temperature detectordetecting a temperature of one or more components constituting one or both of the control portionand the electric motor, and a current detectordetecting a current flowing through the component. When the temperature detected by the temperature detectoris a temperature Td, the current detected by the current detectoris a current Id, and a current corresponding to the temperature Td at a temperature characteristic relating to the current specific to the component is a current Ia(Td), the control portionstops driving the electric motoron the basis of a result of comparison between Ia(Td) and Id.

Electric compressor

The invention provides an intake-air cooling device for an internal combustion engine that can be installed compactly. The invention provides an intake-air cooling device for a gasoline engine equipped with an intercooler that cool intake air with outside air and an evaporator that cools intake air with refrigerant circulating in a bypass refrigeration circuit, disposed in this sequence in an intake-air channel from a supercharger to the gasoline engine. The intercooler is disposed in an outside-air duct through which outside air passes, the evaporator is disposed inside a case through which the intake air passes, and a bottom plate of the case forms part of the outside-air duct.

Intake-air cooling device for internal combustion engine and automobile using the same

The invention provides an air mixing damper apparatus and an air conditioning apparatus for vehicles where the temperature of discharged air can be changed linearly with respect to the operation of an actuator lever. A rotation speed adjustment mechanism is disposed between a plate door type air mixing damper A for opening and closing an air introducing face of a heater core , and a rotation type lever for an actuator driving the air mixing damper A, for adjusting the rotation speed at an initial opening stage X and a final opening stage Z of the air mixing damper A, to a speed lower than at an intermediate opening stage Y.

Air mix damper device and vehicle air conditioner

The air regulator for vehicles is provided with, within a casing, an evaporator which cools air, a heater which reheats the air cooled by the evaporator, and an air mix damper which is disposed on the downstream side of the evaporator and on the upstream side of the heater and in close proximity thereto, and which regulates the amount of air passing through the heater; a heat reflecting surface is formed on the heater side of the air mix damper. By means of this, it is possible to prevent the thermal deformation of the air mix damper by reflecting the radiation from the heater side using the heat reflecting surface. Accordingly, the sliding problems of the air mix damper can be prevented.
