One common type of oil seal is the lip seal, which features a flexible lip that makes contact with the rotating shaft to create a tight seal. Lip seals are often used in automotive engines, gearboxes, and industrial pumps due to their effectiveness in preventing oil leaks. Another popular option is the mechanical seal, which uses a rotating element to maintain constant contact with the shaft, ensuring a reliable seal even at high speeds and pressures.
On the other hand, if the pressure drops below the set point, the spring's tension pushes the diaphragm down, opening the valve and allowing more gas to flow through, thus increasing the pressure. This continuous adjustment allows for a consistent and stable outlet pressure, essential for many applications.
