Valve arrangement for internal combustion engine of vehicle has second valve which is set coaxial with first pressure and opens to direction opposite feed direction if outlet pressure is more than feed pressure

摘要

A first valve (50) has a movable valve head (51) to seal an outlet (56) from an inlet (53) in a valve housing (511). The valve is in a closed position when there is no feed pressure from a feed pump provided in a feed line. A second valve (60) arranged coaxial with the first valve, opens to a direction opposite to a feed direction when the pressure in the outlet is larger than the feed pressure. Independent claims are also included for the following: (a) a feed system for internal combustion engine; (b) and a vehicle.
