Abstract
Official abstract text for this publication.
A pumping system includes s pump, a mechanical coupling device, and a cam shaft. The pump is effective to transfer fuel into an engine. The mechanical coupling device is coupled to the pump. The cam shaft couples to the mechanical coupling device. The cam shaft has an axis extending there through and rotates about the axis. The rotating of the cam shaft is effective to engage the mechanical coupling device and transfer a mechanical force created by the rotating to the mechanical coupling device. The mechanical coupling device is engaged to allow the mechanical force to be transferred to the fuel pump and activate the fuel pump when fuel is to be moved by the pump. The mechanical coupling device is disengaged to disallow the mechanical force from being transferred to the fuel pump and prevent the operation of the fuel pump.
First claim
Opening claim text (preview).
What is claimed is: 1. A pumping system for use in a vehicle, the system comprising: a pump, the pump being effective to transfer fuel into a fuel injection system of an engine; a mechanical coupling device coupled to the pump; a controller; a cam shaft that couples to the mechanical coupling device, the cam shaft having an axis extending there through, the cam shaft rotating about the axis, the rotating of the cam shaft being effective to engage the mechanical coupling devi…
