摘要： A fluid pump includes a driving part, a movable part that is movable by power transmitted from the driving part via a transmission part, a fixed part disposed on a side of the movable part, opposite to the transmission part, to form an operating chamber having an outlet from which a fluid flowing into the operating chamber is pressure-fed to an outside in a liquid state by the movable part, and an introduction passage for introducing a part of the fluid in the operating chamber to the transmission part. Accordingly, the liquid fluid can be introduced to the transmission part such as a bearing through the introduction passage.

摘要： In an air conditioner for a vehicle, when a target rotation speed of an electric compressor calculated by a target rotation speed calculating means is higher than an upper limit set by an upper limit setting means and a noise level is reduced from a level equal to or higher than a predetermined noise level to a level lower than the predetermined noise level, an inverter controls the compressor to stop for a predetermined period of time and subsequently increase rotation speed to the upper limit. Since the compressor is stopped for the predetermined period of time, the rotation speed of the compressor is controlled without detecting a rotational position of the compressor. Therefore, when the target rotation speed is higher than the upper limit and the noise level is decreased lower than the predetermined noise level, an actual rotation speed of the compressor is immediately decreased.

摘要： In a vehicle air-conditioning system, an evaporator is disposed in an air-conditioning case to form a bypass passage through which air bypasses the evaporator, and an opening degree of the bypass passage is adjusted by a bypass door. When a vehicle engine operates, the system performs a cold-storing mode where cold quantity stored in condensed water on the evaporator is increased. On the other hand, when operation of the vehicle engine is stopped, the system performs a cold-releasing mode where air passing through the evaporator is cooled by cold released from frozen condensed water. During the cold-storing mode and the cold-releasing mode, temperature of air blown into a passenger compartment can be adjusted by adjusting the opening degree of the bypass passage. Thus, in the vehicle air-conditioning system, cold-storing quantity in the evaporator can be improved while power-saving effect of the vehicle engine is improved.

摘要： In an electric vehicle air conditioner, unpleasant compressor noise is reduced after issuance of an instruction to stop the operation of the air conditioner. An air conditioner controller calculates a delay time T1 from a map stored in a microcomputer in advance when an air conditioning switch or a blower switch is turned off and initializes a built-in timer to start counting. Thereafter, the speed of rotation of the coolant compressor (the speed of rotation of an electric motor) is decreased at the maximum rate of change of the speed of rotation through an inverter until the calculated delay time T1 passes. After the delay time T1 passes (after the counting by the timer terminates), the coolant compressor is stopped. The delay time T1 recorded in the map is set such that it becomes shorter with a decrease in the blower level.

摘要： An automotive air conditioner which is capable of suppressing periodic torque variation in an engine-driven refrigerant compressor while ensuring performance of returning oil thereto to circumvent periodic variation in a rotational speed of an engine, thereby preventing degradation in motor power performance and drivability of an automobile. A value of target blowout temperature is calculated using a set temperature, indoor air temperature, outdoor air temperature and intensity of solar radiation. A value of first target post-evaporation temperature (TEO1) is calculated according to a determined value of target blowout temperature. Then, a value of second target post-evaporation temperature (TEO2) corresponding to a limit level for ensuring oil return performance is calculated according to the outdoor or indoor air temperature. Thereafter, using a value of first target post-evaporation temperature (TEO1) or second target post-evaporation temperature (TEO2), whichever is smaller, as a target post-evaporation temperature (TEO), a discharge capacity of the refrigerant compressor is controlled so that an actual post-evaporation temperature (TE) will meet the target post-evaporation temperature (TEO).

摘要： A centrifugal type separator is disposed on a downstream side of a temperature-operating type expansion valve. Liquid-phase refrigerant separated herein is again pressure-reduced by an aperture resistance and thereafter inducted to an inlet side of the evaporator by means of a liquid-phase refrigerant discharge passage. Meanwhile, gas-phase refrigerant separated by the separator is returned directly from a gas-phase refrigerant discharge passage to an evaporator outlet side passage, and after being united with superheated gas-phase refrigerant evaporated by the evaporator, is taken into a compressor. A temperature-sensing tube of the expansion valve is disposed further on the downstream side of the foregoing union location so as to enable the temperature of the superheated gas-phase refrigerant evaporated by the evaporator to be sensed accurately.

摘要： A compressor is prevented from the problem of seizure at start-up even when return of lubricant to the compressor is delayed. In such a refrigerant cycle, a bypass passage bypasses an expansion member and an evaporator. The bypass passage opens for a predetermined time when the compressor starts. The predetermined time is dependent upon external temperature, the compressor speed, compressor capacity, etc.
