  • Fuel pump
    Patent number: 10859049
    Abstract: A fuel pump includes a pump head defining a barrel in which a plunger is slidable to pressurise fuel in a pumping chamber, and a fluid-inlet path through which fuel flows in to the pumping chamber under control of an inlet valve during a plunger return stroke. The plunger causes pressurisation of the fuel in the fluid-inlet path. The fuel pump may also include a fluid-outlet path through which fuel flows out of the pumping chamber, preferably under control of an outlet valve, during a plunger pumping stroke.

  • High pressure pump with pump spring sealing sleeve
    Patent number: 10473076
    Abstract: A high pressure fuel pump has a piston extending outside a pump head toward an end provided with a spring seat cooperating with a cam follower. A pump spring compressed between the pump head and the cam follower maintains the follower in contact with a revolving cam. The pump is further provided with a flexible tubular sealing sleeve engaged around the piston and extending between the pump head and the cam follower so that the internal space of the sleeve is sealingly isolated from the outer space.
