Abstract
A fuel pump, including a case, including a first section including a hub and a hole, a second section circumferentially arranged around the first section, wherein a radial space is arranged between the first section and the second section, an inlet in fluid communication with the radial space, a housing chamber arranged adjacent to the first section, and an outlet in fluid communication with the hole, a filter bowl removably connected to the second section, the filter bowl fluidly connecting the radial space with the hole, a valve assembly arranged at least partially in the first section and at least partially in the housing chamber, and a coil operatively arranged to apply a magnetic field to the valve assembly to selectively displace fluid therethrough.
Claims20
A fuel pump, comprising:
- a case, including:
- a first section comprising a hub and a hole;
- a second section circumferentially arranged around the first section, wherein a radial space is arranged between the first section and the second section;
- an inlet in fluid communication with the radial space;
- a housing chamber arranged adjacent to the first section;
- and,
- an outlet in fluid communication with the hole;
- a filter bowl removably connected to the second section, the filter bowl fluidly connecting the radial space with the hole;
- a valve assembly arranged at least partially in the first section and at least partially in the housing chamber;
- and,
- a coil operatively arranged to apply a magnetic field to the valve assembly to selectively displace fluid therethrough.
A fuel pump, comprising:
- a case, including:
- a first section comprising a hub and a hole;
- a second section concentrically arranged around the first section, wherein a radial space is arranged between the first section and the second section;
- an inlet in fluid communication with the radial space;
- a housing chamber arranged adjacent to the first section and the second section;
- and,
- an outlet in fluid communication with the hole;
- a filter bowl removably connected to the second section, the filter bowl fluidly connecting the radial space with the hole;
- a valve assembly arranged at least partially in the first section and at least partially in the housing chamber, the valve assembly including:
- a fuel chamber tube comprising a first end and a second end;
- a check valve assembly arranged in the fuel chamber tube at the first end;
- and,
- a plunger assembly slidingly arranged in the fuel chamber tube at the second end;
- and,
- a solenoid coil concentrically arranged around the plunger assembly, the solenoid coil operatively arranged to produce a magnetic field to displace the plunger assembly in a first axial direction such that fluid is selectively displaced from the inlet to the outlet.

- a case, including:
- a first section comprising a hub and a hole;
- a second section concentrically arranged around the first section, wherein a radial space is arranged between the first section and the second section;
- an inlet in fluid communication with the radial space;
- a housing chamber arranged adjacent to the first section and the second section;
- and,
- an outlet in fluid communication with the hole;
- a filter removably connected to the hub;
- a filter bowl removably connected to the second section and operatively arranged to secure the filter to the case, the filter bowl fluidly connecting the radial space with the hole;
- a valve assembly arranged at least partially in the first section and at least partially in the housing chamber, the valve assembly including:
- a fuel chamber tube comprising a first end and a second end;
- a check valve assembly arranged in the fuel chamber tube at the first end;
- and,
- a plunger assembly slidingly arranged in the fuel chamber tube at the second end;
- and,
- a solenoid coil concentrically arranged around the plunger assembly, the solenoid coil operatively arranged to produce a magnetic field to displace the plunger assembly in a first axial direction such that fluid is selectively displaced from the inlet to the outlet.
