Abstract
A vacuum breaker having a supporting rib and a skirted section is disclosed. The supporting rib is configured to be axially aligned with air slots in an outlet tube and provide a more robust vacuum breaker sleeve under extreme operating conditions. The skirted section can prevent leakage through air slots during high back pressure operating conditions.
