Abstract: An electric compressor 10 includes a compression mechanism 11, an electric motor 12 driving the compression mechanism 11, and a control portion 13 controlling to drive the electric motor 12, incorporated into a single casing, and further includes a temperature detector 14 detecting a temperature of one or more components constituting one or both of the control portion 13 and the electric motor 12, and a current detector 15 detecting a current flowing through the component. When the temperature detected by the temperature detector 14 is a temperature Td, the current detected by the current detector 15 is 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 portion 13 stops driving the electric motor 12 on the basis of a result of comparison between Ia(Td) and Id.

Abstract: 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.

Abstract: There is provided an electric compressor that can protect a component to be protected from heat damage according to a capability of the component. The electric compressor 10 includes a compression mechanism 11, an electric motor 12 that drives the compression mechanism 11, and a control portion 13 that controls to drive the electric motor 12, incorporated into a single casing, and further includes a temperature detector 14 that detects a temperature of one or more components that constitute one or both of the control portion 13 and the electric motor 12, and a current detector 15 that detects a current flowing through the component.

Abstract: There is provided an intake-air cooling apparatus for an internal combustion engine which can be arranged compactly. The intake-air cooling apparatus for an internal combustion engine is configured such that an intercooler that cools intake air with outside air and an evaporator that cools the intake air with refrigerant circulating through a refrigerant circuit are arranged in this order in an intake-air passage from a supercharger to the internal combustion engine, wherein the intercooler is disposed in a duct through which the outside air passes; the evaporator is disposed in a case through which the intake air passes; and one wall of the case constitutes part of the duct.

Abstract: 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 43A for opening and closing an air introducing face 42a of a heater core 42, and a rotation type lever 48 for an actuator 47 driving the air mixing damper 43A, for adjusting the rotation speed at an initial opening stage X and a final opening stage Z of the air mixing damper 43A, to a speed lower than at an intermediate opening stage Y.

Abstract: 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.
