  • Patent number: 10086688
    Abstract: A fuel delivery module is located inside a fuel tank and supplies fuel from the fuel tank to the engine. An in-tank suction fluid filter has a filter body made of combination material layers with porous material and filtration material. An in-tank suction fuel filter functions to filter the fuel and holds a reservoir of fuel for supplying to the fuel pump. The in-tank suction fuel filter acts as the reservoir cavity needed to have a constant supply of filtered fuel available to the fuel pump. The in-tank suction fuel filter has a freeform body that can move upward or downward with thermal expansion of the fuel while maintaining constant contact with the bottom of the fuel tank.

The present depth filtration cartridge functions to remove particulate matter as small as five microns to improve fluid cleanliness level without restricting fluid flow to the pump ensuring its volumetric efficiency. In one embodiment transmission fluid passes through a calibrated orifice in the bypass circuit to regulate flow to the depth filtration cartridge. In an alternate embodiment the depth filter media itself regulates filtration below a predetermined fluid pressure. The internal bypass circuit is installed by accessing a pressurized fluid circuit in the transmission valve body. A hydraulic bypass line interconnects such pressurized fluid circuit with the depth filtration cartridge, which is mounted internally of the transmission housing.

A barrier at one end of the platform in divides the flow of water. The screen intake has a half-cylindrical body and half-cylindrical screens. Transition walls in the screen intake divide the body's hollow and the screens' interiors, and at least one flow modifier communicates the interior with the hollow. These flow modifiers also form a half cylinder with the platform. A manifold in the screens receives a supply of air to clear debris. Forming a half-cylinder, the screen intake on the platform can have a much lower profile for the water source than the normal cylindrical screens, which require half of its diameter in clearance above and below.

  • Patent number: 7455782
    Abstract: A grit removal system for a hollow, completely enclosed emergency water reservoir tank employs a mobile suction head located within the enclosed tank, a flexible suction line coupled between the mobile suction head and the tank outlet, and a particle filtration unit located externally of the tank. The tank has an inlet from a municipal water supply system and an outlet leading to a local water distribution line. The tank is pressurized and maintained at an elevated pressure of preferably sixty to one hundred twenty psi relative to atmospheric ambient pressure. When the local water distribution line is opened, the pressure differential created due to the elevated pressure within the tank drives the mobile suction head so as to move it about the interior surface of the lower portion of the tank. The pressure differential between the interior of the tank and the local water distribution line forces water up through the suction head carrying entrained grit and sand with it.
