Pressure-release device for a transmission housing |
摘要 |
A venting or pressure release system releases pressure from a transmission housing through which extends a transmission shaft. A lower part of the transmission housing forms a collector in which fluid collect. A conduit communicates the collector with a storage container which is substantially sealed against the transmission housing. An overpressure in the transmission housing forces fluid from the collector through the conduit into the storage container. A pressure-release conduit communicates the transmission housing above the collector to the storage container. A shutoff device closes the pressure-release conduit when the transmission shaft is rotating and opens the pressure-release conduit when the transmission shaft is not rotating. This makes possible a rapid compensation of fluid after the transmission has been turned off so that the fluid level can be reliably determined. The shutoff device may be a pilot-controlled valve or a fluid barrier.
