| Zusammenfassung: | An apparatus for electrically simulating a reciprocating gas pump or compressor includes unidirectional devices for simulating intake and discharge valves. The volume of the reciprocating cylinder is modeled by a fixed capacitor coupled in a feedback arrangement with a variable gain amplifier. The gain of the amplifier is preferably controlled by the contents of a digital memory device, which varies the gain to simulate the pumping action of a compressor. The device provides voltage outputs representing the pressure and volume readings obtained in the compressor being simulated. |
