English term or phrase: loaded / unloaded condition or operation of a compressor
Hallo,

noch eine Frage zu diesem Patent: Sollte man dafür "belastet/unbelastet" oder besser "Lastzustand/lastfreier Zustand" benutzen, oder evtl. ganz etwas anderes?

Hier das gesamte Patent zwecks Kontext:
http://worldwide.espacenet.com/publicationDetails/descriptio... (US2013294938)
Der Text stimmt wie gesagt nicht genau mit meiner Version überein, deshalb hier noch ein paar weitere Sätze mit dem gesuchten Begriff, die in der Online-Version evtl. nicht zu finden sind:

The term "loaded" as used herein can be defined as a compressor system mode where air is being compressed into the reservoir. The term "loaded start" as used herein can be defined as a compressor system mode in a loaded condition during a starting phase of the compressor. The term "unloaded" as used herein can be defined as a compressor system mode where air is not being compressed into the reservoir.

In another embodiment, the piston is actuated by cycling the piston within the cylinder with the compressor in an unloaded condition.

During normal or loaded operation of the compressor, on each compression stroke (j) of the high pressure cylinder 210, the measured pressure 342 in the reservoir 180 increases as an additional mass of compressed air is forced through the exhaust port 215 and into the reservoir 180. During each suction stroke (t), the exhaust port 215 is closed and the measured pressure 340 within the reservoir 180 is expected to remain constant. As such, the measured reservoir pressure is expected to increase in a generally step-wise fashion once per revolution of the piston 218. Thus, during loaded operation of the compressor a change in the monitored pressure, or lack of change, correlated with each compression stroke may indicate faulty operation of the compressor.

In another embodiment, the piston is actuated by cycling the piston within the cylinder with the compressor in an unloaded condition. The unloaded condition is maintained by opening one or more of the unloader valves to vent the cylinders and intermediate stage reservoir, if present, to the atmosphere. In an unloaded condition, the crankshaft 250 of the compressor rotates causing the pistons 218, 228, 238 to move within their respective cylinders, however, air flows into and out of the cylinders through the open unloader valves.

During unloaded operations, the exhaust port 215 and exhaust valve 214 of the cylinder 210 are expected to remain closed to maintain a closed volume and constant pressure within the reservoir, provided air is not currently being supplied from the reservoir 180 to pneumatic devices. If the exhaust port 215 and/ or exhaust valve 214 are degraded, such as by corrosion or wear, the exhaust valve may not maintain an air tight seal during unloaded operations and compressed air may leak from the reservoir back through the exhaust port 215 into the cylinder 210. Depending upon the pressure within the reservoir and the nature of the degradation of the exhaust value or exhaust port, a leak may be intermittent or difficult to identify.

Explanation:
Belastete bzw. unbelastete Bedingung oder belasteter bzw. unbelasteter Betrieb eines Kompressors.

Etwas komplizierte Situation. Unter unbelastet verstehe ich hier den Fall, dass (am Anfang) in den drucklosen Behälter gepumpt wird und somit noch kein Gegendruck besteht.
