Product Description

Most pressurized lubrication systems

incorporate an overpressure relief valve to allow

oil to bypass the filter if its flow restriction is

excessive, to protect the engine from oil

starvation. Filter bypass may occur if the filter is

clogged or the oil is thickened by cold weather.

The overpressure relief valve is frequently

incorporated into the oil filter. Filters mounted

such that oil tends to drain from them usually

incorporate an anti-drainback valve to hold oil in

the filter after the engine (or other lubrication

system) is shut down. This is done to avoid a

delay in oil pressure buildup once the system is

restarted; without an anti-drainback valve,

pressurized oil would have to fill the filter before

travelling onward to the engine's working parts.

This situation can cause premature wear of

moving parts due to initial lack of oil.
