摘要:
A structure and method for holding an electric wire connected to the inside of an electric compressor incorporating a motor. The structure has a holding member for holding an electric wire present between a connection terminal section for connection to the outside and a built-in electric device. The structure and method can reliably eliminate possibility of adverse affection to an input electric wire caused by vibration, etc. while preventing a reduction in efficiency of assembly work and an increase in size of the compressor.
摘要:
A hybrid compressor having a first compression mechanism driven only by an outside drive source; a second compression mechanism driven only by a built-in electric motor; suction paths for sucking a gas to be compressed, into the first compression mechanism; communication paths for sucking the gas from the first compression mechanism side into an electric motor side suction chamber; and suction paths for sucking the gas from an electric motor side suction chamber to the second compression mechanism side. The positions and/or the number of the communication paths and/or the suction paths, and/or the positions and/or the number of communication openings and/or suction openings are limited for at least a portion of the gas sucked into the electric motor side suction chamber via the communication paths, where the communication openings are openings of the communication paths and opened at the electric motor side suction chamber and where the suction openings are openings of the suction paths, opened at the electric motor side suction chamber, and located on the opposite side of the communication openings. As a result, a gas flow is formed from the communication openings to the suction openings. A built-in electric motor section can be appropriately cooled in a wide range by a suction gas, so that a rise in temperature in the motor section can be suppressed.

The present invention provides a hybrid compressor system in which its configuration is simplified, its cost and size are reduced, and its reliability is enhanced. In the hybrid compressor system which selectively transmits a driving force of an engine and a driving force of a motor being mounted on a vehicle to a compressor of a vehicle air conditioning device to drive the compressor, the motor is provided with a one-way clutch which selectively transmits the driving force of the motor to the compressor 1.

A dynamotor capable of operating as either a motor or a generator is used with both the armature portion and the field portion thereof capable of being rotated. In the case where a pulley operatively interlocked with the output shaft of the prime mover is mounted on the rotary shaft of the armature portion, the drive shaft of the compressor is mounted on the rotating field portion. Once the dynamotor is operated in motor mode, the rotational speed of the compressor is increased to the sum of the input rotational speed and the rotational speed of the dynamotor. The compressor is stopped by disconnecting a power feed circuit. When the input rotational speed is too high, the dynamotor is operated in generator mode. In this way, the rotational speed is reduced in accordance with the generated electric energy.
摘要:
An air conditioner for a vehicle uses a hybrid compressor (4) including a first compression mechanism driven by a first drive source (2) and a second compression mechanism driven by a second drive source (5), and a single discharge port connected to the first and the second compression mechanisms. The operation of the hybrid compressor is controlled by a controller (15) in accordance with a control mode. The controller has a first operation mode in which the first compression mechanism alone is driven, a second operation mode in which the second compression mechanism alone is driven, a third operation mode in which the first and the second compression mechanisms are simultaneously driven, and a fourth operation mode in which the first and the second compression mechanisms are simultaneously stopped. Depending upon various conditions, the controller selects, as the control mode, one of the first, the second, the third, and the fourth operation modes.

Die Erfindung betrifft eine Pumpenantriebsanordnung mit einem Pumpenantriebselement (70), das durch eine erste oder eine zweite Antriebseinrichtung angetrieben ist. Die Erfindung zeichnet sich dadurch aus, dass das Pumpenantriebselement (70) durch ein Kopplungselement (84) entweder über eine erste Freilaufeinrichtung (91) mit der ersten Antriebseinrichtung oder über eine zweite Freilaufeinrichtung (92) mit der zweiten Antriebseinrichtung drehfest verbindbar beziehungsweise verbunden ist.
