    Abstract: Bei einem Verfahren zur Steuerung des Betriebs eines Kompressors wird der Kompressor von einem Steuergerät zur Vermeidung thermischer Schäden dann abgeschaltet, wenn ein von dem Steuergerät berechneter Temperatur-Schätzwert einen oberen Schwellenwert überschreitet. Hierbei berechnet das Steuergerät unter Heranziehung des Temperatur-Schätzwertes als Zustandsgröße eine Abkühlfunktion, die den zeitlichen Verlauf der Abkühlung des Kompressors repräsentiert. Erfindungsgemäß ermittelt das Steuergerät die Abkühlfunktion ausgehend von wenigstens einem ersten und einem zweiten Temperatur-Schätzwert, die räumlich zueinander beabstandeten Stellen des Kompressors zugeordnet sind, derart, dass die Abkühlfunktion ausgehend von der Temperaturdifferenz zwischen dem ersten und dem zweiten Temperatur-Schätzwert ermittelt wird.

    Abstract: Disclosed is a method for controlling operation of a compressor, according to which the compressor is shut off by a control device in order to prevent thermal damages when an estimated temperature value Ts calculated by said control device exceeds an upper threshold value Tmax while the compressor remains on or is allowed to be turned on when there is a need for compression and a lower threshold value Tmin is not reached. In order to be able to more accurately estimate the estimated temperature and increase the thermal availability of the compressor, the estimated temperature value Ts is indirectly and cyclically determined by means of a mathematical-physical model that characterizes the cooling and heating properties of the compressor.

    Abstract: A method and apparatus for diagnosing components in high-pressure pumps to indicate when a component of the pump head is malfunctioning and to identify the malfunctioning component. In one embodiment, a high-pressure pump head incorporating a diagnostic system in accordance with the invention has a pressurization chamber and a pressurizing member at least partially received in the pressurization chamber. The pressurizing member moves within the pressurization chamber along an intake action to draw fluid into the pressurization chamber and along a pressurizing action to compress fluid in the pressurization chamber. An inlet fluid control assembly is coupled to the pressurization chamber to allow fluid to enter the pressurization chamber during the intake action, and a pressurized fluid control assembly is coupled between the pressurization chamber and an outlet chamber to selectively allow pressurized fluid into the outlet chamber during the pressurizing action. The pump head may also include a diagnostic system to indicate the operational status of each of the inlet fluid control assembly, the pressurized fluid control assembly and other components of the pump head upstream from the inlet fluid control assembly with respect to a fluid flow through the pump head during the pressurizing action.

    Abstract: Provided is an electric compressor whose manufacturing cost is reduced and in which a motor driving circuit can be positively protected. A temperature sensor is provided in the vicinity of a power semiconductor element whose temperature becomes highest among a plurality of power semiconductor elements and control of the number of revolutions of a motor is performed on the basis of temperatures detected by the temperature sensor, whereby it is possible to change the number of revolutions of the motor by using a temperature in the vicinity of a power semiconductor element in a position under the worst temperature conditions as a reference, and it becomes possible to positively protect an inverter circuit without the need for a plurality of temperature sensors.
