摘要： The invention relates to a method and apparatus for determining the switching pressure of a safety appliance which is adapted to safeguard an installation against exceeding or falling below a gas pressure, wherein an increasing pressure is applied to the safety appliance (1), wherein the supplied increasing pressure rises in accordance with an exponential function. Owing to the constant relative increase in the pressure supplied to the safety appliance, it is no longer necessary beforehand to take into account settings of the safety appliance. Errors resulting from incorrect settings by the user are hereby prevented.

摘要： A sampling and rejection device for a boiler or steam generating system is described. The sampling and rejection device receives the condensate or fluid and allows a volume of the condensate to liquefy or the fluid to build up in the interior of the sampling and rejection device. One or more conductivity, pH, and temperature sensors or probes are positioned in the sampling and rejection device to measure the condensate. The sampling and rejection device includes a collection vessel to hold and temporarily store the condensate. The sampling and rejection device includes an outlet or a return line (to a central boiler) and a drain line. If the sensor measures undesirable conductivity, pH, or temperature in the condensate in the collection vessel, then a valve to the drain line is opened and the condensate is rejected.

摘要： A valve assembly senses the cumulative volume of hydraulic fluid that has passed to an actuator and senses and subtracts from that cumulative volume the volume of return fluid that has passed from the actuator. When the difference between the volumes exceeds a preset value, the system shuts off the flow to the actuator to prevent further loss of fluid from a leak. The assembly may employ separate sensors in separate pressure and return lines or a common line with a common sensor which reverses signal polarity when flow reverses. Target flowmeters with signal adding and subtracting circuits may provide the differential volume information.

摘要： A method of combining a first fluid from a first source (1) with a second fluid from a second source (16) in a desired ratio, by measuring the flow rate and pressure of the first fluid (at 12 and 14) prior to combining (at 10), and determining from this the desired flow rate and pressure at which the second fluid should be added to achieve the desired ratio. The pressure and flow rate of the second fluid is measured (at 6 and 8) and provides a feedback loop to ensure that the second fluid is being added at the desired flow rate and pressure to achieve the desired ratio. The pressure and flow rate of the second fluid may be controlled by multiple pumps 2 of different power.

摘要： Die vorliegende Erfindung betrifft ein Druckregelungsventil zur Regelung des Öldrucks in einem Ölversorgungssystem vorzugsweise einer Brennkraftmaschine mit innerer Verbrennung, mit einem ersten Arbeitsraum (6), der mit einer Ölleitung in Verbindung steht, mit einem zweiten Arbeitsraum (7), der mit einer Ölversorgungsleitung in Verbindung steht, und mit einem Steuerschieber (3), der im wesentlichen durch den Öldruck im ersten Arbeitsraum (6) bewegbar ist, um bei Überschreiten eines ersten vorbestimmten Öldrucks eine Absteueröffnung 10 frei zugegeben, über die Öl aus dem zweiten Arbeitsraum (7) in ein Rücklaufsystem abgesteuert wird.
Eine bauliche Vereinfachung wird dadurch erreicht, daß der Steuerschieber (3) ein Steuerelement aufweist, das durch den Öldruck im zweiten Arbeitsraum (7) relativ zu einem Hauptkörper (4) des Steuerschiebers (3) bewegbar ist und das bei Überschreiten eines zweiten vorbestimmten Öldrucks im zweiten Arbeitsraum (7) die Absteueröffnung (10) freigibt, über die Öl aus dein zweiten Arbeitsraum (7) in das Rücklautfsystem abgesteuert wird.
