Device for automatic ventilation and de-aeration of pressure fluid supply system

摘要

The device has an automatic valve (14) with a closure body (32) that opens against a de-aerating direction and an actuation unit that is loaded in an opening direction and attached to the closure body. The actuation unit is over-pressured by a pressure fluid that influences on the closure body. The closure body is loaded by a spring unit (36), where interpretation-spring force of the spring unit is larger than counterforce. The counter force is produced by a weight component of the closure body acting in a closure direction and is applied by an exhaust air flow on the closure body.
