Hybrid compressor
View Patent ↗A hybrid compressor includes a first compression mechanism, which is driven by a first drive source, and a second compression mechanism, which is driven by a second drive source, and a second radial axis of a second housing of the second compression mechanism is offset relative to a first radial axis of a first housing of the first compression mechanism, or a second diameter of the second housing of the second compression mechanism is less than a first diameter of the first housing of the first compression mechanism, or both. When a significant external force is applied to the front end of a vehicle containing the compressor, most of the external force may be absorbed by the first compression mechanism portion of the compressor, thereby reducing or avoiding damage to the second compression mechanism. In particular, when the second drive source is an incorporated electric motor, damage to the electric motor may be reduced or avoided.
1. A hybrid compressor comprising:
a first compression mechanism, which is driven by a first drive source for driving a vehicle; and
a second compression mechanism, which is driven by a second drive source, wherein a second radial axis of a second housing of said second compression mechanism is offset relative to a first radial axis of a first housing of said first compression mechanism, and said hybrid compressor is mounted on said vehicle, wherein an offset direction of said second radial axis of said second housing of said second compression mechanism relative to said first radial axis of said first housing of said first compression mechanism is away from a front end of said vehicle.
2. The hybrid compressor of claim 1 , wherein said first compression mechanism is driven exclusively by said drive source for driving said vehicle.
3. The hybrid compressor of claim 1 , wherein said second compression mechanism is driven by an electric motor.
4. The hybrid compressor of claim 1 , wherein said offset direction of said second radial axis of said second housing of said second compression mechanism from said first radial axis of said first housing of said first compression mechanism is in a horizontal direction away from said front end of said vehicle.
5. The hybrid compressor of claim 1 , wherein said offset direction of said second radial axis of said second housing of said second compression mechanism from said first radial axis of said first housing of said first compression mechanism is in a direction different from a horizontal direction and away from said front end of said vehicle.
6. The hybrid compressor of claim 1 , wherein each of said first and second compression mechanisms is a scroll-type compression mechanisms comprising a fixed scroll, and said fixed scrolls of each of said compression mechanisms are disposed to extend in opposite directions from a common valve plate.
7. A hybrid compressor comprising:
a first compression mechanism, which is driven by a first drive source for driving a vehicle; and
a second compression mechanism, which is driven by a second drive source, wherein a second diameter of a second housing of said second compression mechanism is less than a first diameter of a first housing of said first compression mechanism, and said hybrid compressor is mounted on said vehicle, wherein an offset direction of said second radial axis of said second housing of said second compression mechanism relative to said first radial axis of said first housing of said first compression mechanism is away from a front end of said vehicle.
8. The hybrid compressor of claim 7 , wherein said first compression mechanism is driven exclusively by said drive source for driving said vehicle.
9. The hybrid compressor of claim 7 , wherein said second compression mechanism is driven by an electric motor.
10. The hybrid compressor of claim 7 , wherein said first compression mechanism is driven exclusively by said drive source for driving said vehicle, and said second compression mechanism is driven exclusively by an electric motor incorporated into said compressor.
11. The hybrid compressor of claim 7 , wherein a second radial axis of said second housing of said second compression mechanism is offset relative to a first radial axis of said first housing of said first compression mechanism.
12. The hybrid compressor of claim 7 , wherein said offset direction of said second radial axis of said second housing of said second compression mechanism from said first radial axis of said first housing of said first compression mechanism is in a horizontal direction away from said front end of said vehicle.
13. The hybrid compressor of claim 7 , wherein said offset direction of said second radial axis of said second housing of said second compression mechanism from said first radial axis of said first housing of said first compression mechanism is in a direction different from a horizontal direction and away from said front end of said vehicle.
14. The hybrid compressor of claim 7 , wherein each of said first and second compression mechanisms is a scroll-type compression mechanisms comprising a fixed scroll, and said fixed scroll of each of said compression mechanisms are disposed to extend in opposite directions from a common valve plate.
15. A vehicle comprising a hybrid compressor, wherein said hybrid compressor comprises:
a first compression mechanism, which is driven by a first drive source for driving the vehicle; and
a second compression mechanism, which is driven by a second drive source, wherein a second radial axis of a second housing of said second compression mechanism is offset relative to a first radial axis of a first housing of said first compression mechanism, and said hybrid compressor is mounted on said vehicle, wherein an offset direction of said second radial axis of said second housing of said second compression mechanism relative to said first radial axis of said first housing of said first compression mechanism is away from a front end of said vehicle.
16. A vehicle comprising a hybrid compressor, wherein said hybrid compressor comprises:
a first compression mechanism, which is driven by a first drive source for driving a vehicle; and
a second compression mechanism, which is driven by a second drive source, wherein a second diameter of a second housing of said second compression mechanism is less than a first diameter of a first housing of said first compression mechanism, and said hybrid compressor is mounted on said vehicle, wherein an offset direction of said second radial axis of said second housing of said second compression mechanism relative to said first radial axis of said first housing of said first compression mechanism is away from a front end of said vehicle.
