A coupling stay includes a support inner peripheral surface extending along a rotational axis and providing radial support to a rotatable shaft portion of a pump unit, which extends along the rotational axis. A support lateral surface extends in a longitudinal direction and provides thrust support to the pump unit. The support inner peripheral surface extends from the support lateral surface in the transverse direction. A lock claw projects from the coupling stay. A lock projection projects from the pump unit and is operable to lock rotation of the pump unit relative to the coupling stay about the rotational axis upon fitting of the lock projection between the support lateral surface and the lock claw. A height of a contact part of the lock projection, which contacts the support lateral surface, is limited to be equal to or lower than the rotational axis.

A vehicle tank having a container and a pair of spaced apart baffle plates directly connected to walls of the container to define a swirl pot. The baffle plates have at least one orifice which lies spatially above the swirl pot, and within the swirl pot, the baffle plates have valves to allow an inflow of fuel into the swirl pot.

The present invention related to a connecting device (1) between a liquid tank made of plastic material (2) and a Liquid Delivery Module (3) on board of a vehicle. According to the invention said connecting device (1) comprises a tubular member (10) It provided to be inserted into the liquid tank (2), said tubular member (10) having a first end portion (100) and a second end portion (101) provided to constitute a swirl pot (4), and a flange (11) located on the external part of the tubular member (10), a surface (110) of the flange (11) being provided to be welded to an external surface of a tank wall (2), the connecting device (1) comprising a connecting means (12) on the first end portion (100) of the tubular member (10), said first end portion (100) being located on the tubular member (10) relative to the flange (11) on the other side of the flange surface (110) provided to be welded to the liquid tank (2), said connecting means (1) being provided for the fixing of the Liquid Delivery Module (3) to the tubular member (10), the second end portion (101) of the tubular member (10) comprising an opening (1010) provided to allow entry of the liquid in the tubular member (10), the first end portion (100) comprising an opening (1000) provided for the insertion of the Liquid Delivery Module (3).

A total dimension of spacing dimensions of a gap provided by a metal rod on a side opposite to a metal housing in a first assembling structure and a second assembling structure is set to be larger than a difference in a thermal expansion amount between a resin lid main body and the metal housing in a reference radial direction when a temperature exceeds a reference temperature. A total dimension of each of a spacing dimension of a gap provided by the metal rod on a side toward the metal housing and a spacing dimension between a resin protrusion and the metal housing in the first assembling structure and the second assembling structure is set to be larger than a difference in a thermal shrinkage amount between the resin lid main body and the metal housing in the reference radial direction when a temperature falls below the reference temperature.

The present disclosure relates to a plastic tank, particularly a plastic fuel tank, with a pot-like installation body arranged on the inside of the tank, as well as a method for producing the same. According to the present disclosure, a ring body is provided which is arranged on an end portion of the installation body (24), wherein the ring body is engaged in an undercut section in the tank wall, and the installation body is engaged in the ring body.

The present disclosure relates to a fuel tank having a module pot, which forms a first separate fuel reservoir for a fuel pump arranged inside the fuel tank. To prevent a gap in delivery of fuel to supply the first fuel reservoir in certain operating conditions, in particular when there is persistent lateral acceleration, according to the invention, a second separate fuel reservoir arranged separately from the first fuel reservoir inside the fuel tank is proposed, such that fuel is transferred from the second fuel reservoir into the first fuel reservoir at least when a predetermined acceleration level acting on the fuel tank is exceeded.

A fuel collection device for a motor vehicle, includes: a splash pot; and a prefilter arranged in a bottom region of the splash pot. The prefilter has first annular part structures and second annular part structures, the first and second annular part structures being arranged so as to lie opposite one another.

A fuel pump system of a hybrid vehicle is provided. The fuel pump system prevents a fuel pump from continuing to operate when fuel is exhausted, whereby the fuel pump may be damaged. The pressure of fuel is measured in response to exhaustion of fuel, and when the pressure of fuel is low, fuel is circulated within the fuel pump instead of being supplied to the engine side, thereby preventing the fuel pump from being stuck due to frictional heat

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.
