摘要： A fuel pump for a vehicle includes a pump section having a flow channel and a rotatable impeller cooperating with said flow channel to pump fuel therethrough. The fuel pump also includes a motor section disposed adjacent the pump section and having a motor to rotate the impeller. The fuel pump further includes an outlet section disposed adjacent the motor section to allow pumped fuel to exit the fuel pump. The impeller includes a plurality of blades that are generally V shaped and have thinned edges.

摘要： A check valve for a fuel pump of a vehicle includes a valve housing adapted to be disposed in an outlet member of the fuel pump and a valve seat formed on the valve housing. The check valve also includes a valve member disposed in the valve housing and having a closed position to engage the valve seat to prevent fuel from flowing through the outlet member and an open position to allow fuel to flow through the outlet member. The valve housing has a vortex abating geometry located near the valve seat to add turbulence to fluid flow past the valve seat when the valve member is in the open position.

摘要： A pressure regulator assembly for a fluid system includes a housing having at least one cavity therein and a valve seat disposed in the at least one cavity and having an aperture extending therethrough. The pressure regulator assembly also includes a movable valve member disposed in the at least one cavity of the housing. The valve member has a closed position to engage the valve seat to prevent fluid from flowing into the at least one cavity and an open position to disengage the valve seat to allow fluid to flow into the at least one cavity. The pressure regulator assembly further includes a biasing mechanism disposed in the at least one cavity to bias the valve member toward the valve seat to close the aperture. The valve seat and the valve member and the biasing mechanism are aligned linearly along an axis of the valve housing.
