| A motor-driven compressor includes an electric motor driven by a motor driver, which includes a switching element that converts DC voltage from a battery to AC voltage. A temperature detector detects the temperature of the switching element. A voltage detector detects DC voltage applied to the switching element from the battery. A control unit suspends the switching operation of the switching element when the detected temperature rises to a temperature threshold. The control unit reduces counter electromotive force generated by the electric motor. The controller changes the temperature threshold such that the temperature threshold gradually increases from when the detected DC voltage is the highest voltage in the applicable voltage range of the battery to when the detected DC voltage is the lowest voltage in the applicable voltage range. | ||||||

| An oil supply groove 12 in communication with a pump room 2A is formed above a bearing 2B of a housing 2, and an open air groove 14 in communication with an atmospheric air is formed at a position rotated around the bearing 2B by 90° from the oil supply groove. In a shank 3B of a rotor 3, a branch passage 11a branching from an oil passage 11 formed in its axial direction to the diametrical direction of the shank, and an open air passage 13 formed in the direction perpendicular to the branch passage are formed.Then, the branch passage and the oil supply groove communicate with each other, at the same time, the open air passage and the open air groove are arranged to also communicate with each other, and when the oil passage and the oil supply groove communicate with each other as the rotor stops, then an atmospheric air flowing in from the open air passage eliminates a negative pressure in the pump room, thereby the lubricating oil is prevented from flowing into the pump room in large quantities.An amount of the lubricating oil flowing into pump room at stop of the rotor can be reduced to prevent the vane from being damaged and an amount of the lubricating oil consumed due to rotation of the rotor can be controlled. | ||||||
| 48 | Scroll compressor protector | US700289 | 1991-05-15 | US5118260A | 1992-06-02 | Howard H. Fraser, Jr. |
| The motor protector for a motor is located so as to be responsive to the discharge temperature of a compressor. The protector is thereby responsive to motor current and compressor discharge temperature. Additionally, by conduction, the protector is responsive to the motor temperature. For scroll compressors, specifically, this provides protection from excess heating of the scroll wraps without requiring an additional sensor. | ||||||
| 49 | Temperature sensitive solenoid valve in a scroll compressor | US133576 | 1987-12-14 | US4820130A | 1989-04-11 | David H. Eber; Peter A. Kotlarek; Ronald W. Okoren |
| Inside the hermetic shell of a scroll compressor, a normally closed solenoid valve seats against the back side of a stationary scroll plate to close a discharge opening through the plate. A coil circuit that actuates the valve has an electrical resistance that increases with temperature. The temperature dependent resistance allows the coil circuit to also function as a discharge temperature sensor. Should the discharge gas over-heat, the compressor motor and the valve are de-energized in response to the resistance exceeding a predetermined limit. The closed valve prevents backflow from rapidly reversing the rotational direction of the compressor, which can be extremely noisy and damaging to the compressor. Both the valve and the compressor motor are energized at the same time, regardless of the compressor's direction of rotation. Should the compressor motor be inadvertently wired to operate in reverse, the solenoid valve still opens to prevent destructively low pressure from developing between the scroll plates. | ||||||
