Lobe design for fuel pump actuation
A fuel system may include a fuel pump and a drive shaft. The fuel pump may include a reciprocating member and the drive shaft may include a lobe member engaged with the reciprocating member. The lobe member may linearly displace the reciprocating member and drive the fuel pump. The lobe member may i...

| Zusammenfassung: | A fuel system may include a fuel pump and a drive shaft. The fuel pump may include a reciprocating member and the drive shaft may include a lobe member engaged with the reciprocating member. The lobe member may linearly displace the reciprocating member and drive the fuel pump. The lobe member may include a first lobe having a first opening flank driving a first compression stroke of the fuel pump through engagement with the reciprocating member. The first lobe may have a profile providing a constant velocity for the linear displacement of the reciprocating member for a portion of the first compression stroke. |
