摘要： Um einen Rezipienten im Hochvakuum zu betreiben, wird in der Regel ein zweistufiges Vakuumsystem mit einer Endvakuumpumpe und einer Vorvakuumpumpe eingesetzt. Bei einem Stromausfall werden die Vakuumpumpen langsam belüftet. Es können störende Rückdiffusionen, insbesondere von nasslaufenden, speziell ölgedichteten Vorvakuumpumpen, auftreten, außerdem wird der Rezipient belüftet. Säuberungsarbeiten und erneutes Aufbauen des Hochvakuums sind aber zeit- und kostenaufwändig. Erfindungsgemäß wird zwischen Endvakuumpumpe (03) und Vorvakuumpumpe (05) ein erstes Ventil (09) vorgesehen, das bei einem Stromausfall schlagartig geschlossen wird und das Hochvakuum (P vac ) und die Endvakuumpumpe (03) über Stunden sichert. Nach Stromrückkehr wird das erste Ventil (03), bei dem es sich um ein elektropneumatisches Magnetventil (13) handeln kann, erst nach einer an einer Verzögerungseinrichtung (10) einstellbaren Zeitverzögerung (T VZ1 ) wieder geöffnet, sodass dann ein sicherer Pumpenbetrieb gewährleistet ist, der Rückdiffusionen und Belüftungen verhindert. Als Modifikation kann analog an der Vorvakuumpumpe (05) ein zweites Ventil (14) vorgesehen sein. Derartige Rezipienten (01) werden beispielsweise in der Massenspektrometrie zur Materialanalyse im Zusammenhang mit Klimaforschung eingesetzt.

摘要： 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.

摘要： It is an object of the present invention to improve the reliability of a compressor by appropriately measuring the temperature inside the compressor. A compressor pertaining to the present invention is equipped with a casing (10), a compression mechanism (15), a drive shaft (17), a main frame (23), a motor (16), a flow path forming member (91), and a temperature measuring mechanism (76). The casing stores lubricating oil in its bottom portion. The compression mechanism compresses refrigerant. The drive shaft drives the compression mechanism. The main frame has the compression mechanism placed on it and supports the drive shaft in such a way that the drive shaft may freely rotate. The motor drives the drive shaft. The flow path forming member forms an oil flow path (92). The oil flow path is a space located in the neighborhood of an inner peripheral surface of the casing and through which lubricating oil that lubricates sliding portions including the compression mechanism and the drive shaft flows. The temperature measuring mechanism is disposed outside the casing. The temperature measuring mechanism measures the temperature of a section of an outer peripheral surface of the casing positioned in the neighborhood of the oil flow path.

摘要： A coil (252) of an electric motor (M) is cooled by refrigerant. A controller for the electric motor (M) controls a current supplied to the coil (252) within a range less than or equal to a predetermined maximum value (Imax). A temperature detection section (27) detects either a temperature of the coil (252) or a temperature about the coil (252). When a detection temperature (Θx) that is detected by the temperature detection section (27) prior to activation of the electric motor (M) reaches a predetermined reference temperature (Θo), a limiting section (C) executes a limiting control to limit an upper limit value of the current supplied to the coil (252) to a limiting value that is less than the maximum value (Imax). Accordingly, the coil of the electric motor is protected without stopping the operation of the electric compressor immediately after activation (Fig. 1A).
