Abstract: A check valve includes a body defining a passageway through which fuel flows in a first fuel-flow direction during pump operation. The check valve also includes a seat, a seal member, and a biasing member biasing the seal member toward the seat. The seal member is movable between a first seated position in which the seal member is engaged with the seat and the pressure in the fuel rail is substantially equal to the operating pressure, and a second seated position in which the seal member is engaged with the seat and a residual pressure in the fuel rail is substantially less than the operating pressure. The seal member and the seat define a leak path between the fuel pump and the fuel rail permitting fuel to flow in a second fuel-flow direction opposite the first fuel-flow direction when the seal member is in the second seated position.

Abstract: A fuel pressure relief valve includes a body defining a passageway having an inlet end in communication with a fuel pump and an outlet end in communication with a fuel rail. The valve also includes a seal member moveable between a first position in which the seal member is seated against the outlet end, and a second position in which the seal member is unseated from the outlet end. The valve further includes a biasing member biasing the seal member toward the second position. The seal member moves from the second position to the first position immediately after fuel pump shutoff to maintain pressure in the fuel rail. The seal member moves from the first position to the second position when fuel in the fuel rail drops to a residual pressure substantially less than the operating pressure to provide a leak path between the fuel pump and the fuel rail.

Abstract: A page lifting device for use with loose-leaf binders containing binding rings. The leaves of the page lifter are formed from one or more stiff sheets of material or loops of stiff wire, rotatably affixed at their inner edges to an attaching member that is fixedly attached to the binding-ring base cover. The pivot axis between the leaves and attachment member is located close to the axis of the substantially circular binder rings which, when the binder is closed, causes the page lifter leaves to envelope and lift the loose-leaf pages away from the binder spine. The page lifter leaves can contain slots or holes therein, which allow them to fit over the binder rings on closing. The attaching member is fixedly attached to the binding-ring base using pressure sensitive adhesive, that is either directly on the attaching member or on a surface of foam tape. The pressure sensitive adhesive is protected by a peel-off protective cover.
