Attributes
- Allows pressure and vapors to escape from the engine crankcase and prevents pressure buildup
- Distributes loads and reduces stress concentrations to improve overall structural strength.
Applications
The crankcase breather is used to ventilate the crankcase of an internal combustion engine.
