Abstract: A motor driven compressor has a motor and a compressing mechanism connected to the motor through a rotary shaft, which is located within a housing, and an offset of phase is set between a stator and a rotor. The rotor is mounted to the rotary shaft, allowing the rotor to rotate so that it may be magnetized. Further, the motor driven compressor has a driving member driven together with the rotary shaft, a communication gas hole formed within the housing and extending from a suction port to a discharge hole, and a mark positioned along a radial axis on a first end surface of the driving member. The mark is used for setting the offset of phase between the stator and the rotor on the basis of a mark, by positioning the mark opposite the suction port. Accordingly, the motor driven compressor has a structure, which allows the rotor to be readily magnetized and may reliably set the offset of phase between the rotor and stator for magnetizing the rotor.

Abstract: An air conditioning system includes a refrigerant circuit. The refrigerant circuit includes a compressor for receiving a refrigerant gas and for compressing the refrigerant gas, and a condenser for condensing a portion of the compressed refrigerant gas into a liquid refrigerant. The refrigerant circuit also includes an expansion valve for reducing a pressure of the condensed liquid refrigerant, and an evaporator for evaporating the condensed liquid refrigerant. Moreover, the compressor is driven by an electric motor which controls a rotational speed of the compressor via an inverter, and a temperature of the inverter is decreased by the refrigerant circuit. The system also includes an electric circuit for determining whether a temperature of the inverter is greater than a first predetermined temperature, and an electric circuit for controlling a rotational speed of the compressor. Specifically, when the temperature of the inverter is greater than the first predetermined temperature, the electric circuit decreases the rotational speed of the compressor.

Abstract: In a scroll type compressor in which a compression mechanism compresses a gaseous fluid with moving the gaseous fluid along a spiral path to produce a compressed gas, an escaping path is provided for escaping the compressed gas from the compression mechanism at an intermediate portion of the spiral path. A pressure transmission path transmits pressure of the compressed gas to a valve mechanism which is for controlling an open and an close of the escaping path. The pressure transmission path has a delay mechanism for delaying transmission of a change of the pressure to the valve mechanism.

Abstract: A scroll-type variable displacement compressor for use in an air conditioning system of a vehicle has a fixed scroll and an orbiting scroll with a lowered minimum operating capacity. A cylinder is formed within an end plate of the fixed scroll and accommodates a capacity control mechanism and a plurality of pairs of bypass holes which penetrate the end plate of the fixed scroll and the cylinder perpendicularly. Via one of a pair of bypass holes, the cylinder communicates with a compression chamber enclosed by the orbiting scroll and the fixed scroll, and via the other of the pair of bypass holes, the cylinder communicates with a low pressure chamber provided within rear portions of a compressor housing. One portion of the low pressure chamber is always open to the suction chamber. The communication between the cylinder and the low pressure chamber is controlled by the position of a piston slidably accommodated within the cylinder. When the thermal load for the air conditioning system is low, the piston retreats to the recessed position of the cylinder, opening the pairs of bypass holes. By providing the low pressure chamber, an extra branch path for returning refrigerant gas is formed, in addition to the conventional returning path. Thus, pressure loss from the compression chamber through the suction chamber is effectively reduced. As a result, the capacity control mechanism of the present invention increases the feed back of refrigerant gas from the compression chamber to the suction chamber. Thus, the capacity control mechanism of the present invention lowers the minimum operating capacity more than that of a conventional device, without any undesired increase in the size or weight of the compressor.
