Abstract

The invention discloses a laminated restrictor. The laminated restrictor comprises baffle plates (1), oil retaining plates (2), a wall plate (4), a vent pipe (5) and a box inner wall (6). According to the laminated restrictor, the integral structure is simple, manufacturability is good, and cost is relatively low; the laminated restrictor can be properly improved according to different requirements of a ventilating system on the laminated restrictor; and the laminated restrictor can be independently utilized and arranged in a vent pipeline, and can be integrated in other lubricating oil accessories like a lubricating oil tank, so that the laminated restrictor is quite wide in application range and has relatively high utilization value.

Description

technical field [0001] The invention relates to a throttling device, in particular to a layered throttling device used in the ventilation sub-system of the lubricating system of a small aviation gas turbine engine. Background technique [0002] In the aviation gas turbine engine lubrication system, the size of the ventilation flow is an important factor affecting the oil consumption. If the ventilation flow is large, the oil consumption will be greater. Therefore, from the perspective of reducing the oil consumption, the Methods of reducing ventilation flow. Although the existing centrifugal ventilator can separate the oil mist in the ventilation air, the best centrifugal ventilator can only separate the oil droplets larger than 2-3μm, and the ventilation flow still contains a certain amount of unseparated tiny oil droplets. In order to reduce lubricating oil consumption, appropriate measures should be taken in the design of the lubrication system to reduce the ventilation...
