Altitude compensation valve assembly |
摘要 |
An altitude compensation valve assembly comprising a housing structure having a bellows and a check valve unit. The check valve unit is supported for movement between a closed position, where communication between a fluid under pressure introduced into an inlet port of the valve assembly is discommunicated from the atmosphere, and an opened position where such communication is established. The check valve unit is normally biased towards the closed position and is moved towards the opened position when the pressure introduced through the inlet port exceeds a predetermined value determined in consideration with change in a altitude in which the valve assembly is operated to compensate for reduction in pressure resulting from change in altitude. |
