ABSTRACT:
The present invention relates to the field of devices for withdrawing fuel for motor vehicle tanks.
Numerous types of device have already been proposed for this purpose.
The present invention is now aimed at proposing a new type of fuel-drawing device with better properties than the known devices.
This aim is achieved according to the present invention by virtue of a fuel-drawing device for a motor vehicle tank, of the type comprising a housing which bears a withdrawing pump and a filter placed on the pump outlet, characterized in that the filter is annular in shape, that it is arranged in a chamber radially external to the housing, that the pump is associated with a vibration damper, and the pump and the vibration damper are arranged in the central space of the filter, and the housing has a nozzle which communicates with the inlet to the filter and which controls a jet pump designed to fill a reserve bowl associated with the pump.
This arrangement in particular allows a very large filter to be fitted, offering the device a long life.
