    Abstract: Die Erfindung nutzt die neue Erkenntnis, daß bei Störungen, insbesondere Undichtigkeiten an einer Pumpe mit mehreren Verdrängern, an der Druckseite charakteristische Änderungen der Pulsationen des Förderstroms bzw. des Drucks auftreten. Durch entsprechende Meßorgane werden diese Änderungen erfaßt und für eine Störungsanzeige ausgewertet.

    Abstract: PROBLEM TO BE SOLVED: To provide an air compressor capable of enhancing safety by coping even with a case where a replacing object is not a recommended item. SOLUTION: This air compressor has a compressor body 1 for compressing air, and the replacing object (in detail, for example, a belt 2, a suction filter 5, a separator element 8 and an oil filter 13) changing in response to use together with operation of this compressor body 1, and has a control device 17 for computing a service time of the replacing object, from an operation time of the compressor body 1, discriminating whether the replacing object is a recommended item or not, determining whether or not the service time of the replacing object, which is discriminated as a recommended item, exceeds a preset first reference time, but determining whether the service time of the replacing object, which is discriminated as the one which is not the recommended item, exceeds a second reference time which has been preset so as to be shorter than the first reference time, and notifying if the reference time is exceeded.

    Abstract: PROBLEM TO BE SOLVED: To eliminate necessity of an independent reaction agent level sensor. SOLUTION: A fluid delivery system for delivering a metered dose of fluid from a supply tank 28 to a downstream chamber or vessel 10, comprises a pump apparatus 20 comprising a pump plunger 32 which is operable to perform a pumping stroke under control of an electromagnetic actuator 36, including a solenoid 36a, to effect delivery of the fluid and a control unit 24 for supplying an input signal 58 to the solenoid to initiate a current flow to the solenoid and thereby initiate movement of the pump plunger. An electronic device 54 provides an output signal to indicate that movement of the pump plunger has stopped at an end of the pumping stroke of a pump plunger, and a timer determines a time difference between the input signal 58 being supplied to the solenoid and the output signal being output by the electronic device 54. A processor 26 compares the time difference with a predetermined time difference and determines, as a result of the comparison, whether or not the pump plunger has performed a valid pumping stroke in which an intended volume of fluid is displaced, whether or not the stroke can be used for total flow quantity calculation.

    Abstract: The device (1) for counting the strokes of a piston (3) sliding within a cylinder (2) comprises a support (5) housing a magnet (6) which generates a magnetic field (7). The support (5) also houses a sensor (9) arranged to sense the magnetic field (7), such that the passage of the piston (3) into a position corresponding with the magnet (6) causes a disturbance in the magnetic field (7), which is sensed by the sensor (9), to indicate a stroke of the piston (3).
