Technical Field

The present application relates to filter elements for filtering fluid in internal combustion engine systems or the like.

Background

A thermal recirculation valve ("TRV") is a valve configured for high resolution temperature control of fuel. The TRV is designed to control the return flow of heated fuel back into the module to increase the temperature of the fuel before it exits the module to provide precise temperature control of the feed fuel that is delivered downstream to the high pressure pump and/or other downstream components. The TRV provides improved performance due to its unique positioning and internal sealing that allows temperature control. For example, the TRV may facilitate delivery of a hot fuel return flow to the filter during cold conditions and drain back to the tank during normal operating modes.

Priming operation (priming operation) is used to remove all air from the system and this is achieved by various pump mechanisms (e.g. manual or electric). During priming, dirty fuel is drawn from the canister (pull) by the suction created by the priming pump (priming pump), which then travels through the media and to the outlet side, and removes all air during this stage. Since the TRV channel is connected to the canister, there is a risk that air will be sucked out of the canister by the suction force generated by the pump if the TRV channel is not blocked during priming. This additional air increases the strength of the priming, greatly increasing the number and force of pumping strokes to remove all of the air.
