Antidrainbackventtiili
Antidrainbackventtiili, also known as an anti-drainback valve, is a component used in certain lubrication systems, particularly in automotive engines and other machinery. Its primary function is to prevent lubricating oil from draining out of the system, such as the oil filter and oil passages, when the engine or machine is shut off. This is crucial for ensuring that the engine or machine receives immediate lubrication upon startup, minimizing wear and tear during the critical moments before oil pressure is fully established.
The valve typically consists of a spring-loaded flap or diaphragm that remains closed when the system is
This feature is especially important in applications where the oil filter is mounted above the oil sump,
