| 1. | Expansion valves were used for stationary engines and marine engines.
|
| 2. | FSDs may utilize one of several technologies : expansion valves.
|
| 3. | Once again these engines were used to experiment with a short boiler and Meyer expansion valve gear.
|
| 4. | As it passes through an expansion valve, it is cooled and then vaporises into a gaseous state.
|
| 5. | It was usual for expansion valves to be fitted only to the HP ( high-pressure ) cylinder.
|
| 6. | Between points 4 and 5, the saturated liquid refrigerant passes through the expansion valve and undergoes an abrupt decrease of pressure.
|
| 7. | They were not used for locomotives, although expansive working was achieved by the use of the later variable expansion valve gears.
|
| 8. | The condensed and pressurized liquid refrigerant is next routed through a thermal expansion valve where it undergoes an abrupt reduction in pressure.
|
| 9. | The high pressure liquid then enters the expansion valve where the TX valve allows a portion of the refrigerant to enter the evaporator.
|
| 10. | A thermal expansion valve is a key element to a heat pump; the cycle that makes air conditioning, or air cooling, possible.
