A delivery device for the fuel of an internal combustion engine has a fuel tank () from which at least one fuel pump () delivers fuel via a fuel supply line () and via at least one fuel filter () to a fuel consumer (). The consumer () is connected to the fuel tank () via a fuel return line (). A control device () is connected between the supply line () and the return line (). The control device establishes a fuel-conveying connection () between the return line () and the supply line () when the temperature in the fuel tank () falls below a predeterminable threshold temperature and at a predeterminable threshold pressure in the return line ().

Delivery device for the fuel of an internal combustion engine

A filter device usable with diesel fuels, includes a filter element () exchangeably accommodated in a filter housing. A fluid pump device () having two pump chambers () is part of the filter device. The pump chambers, by a pump piston () guided in the chambers in a longitudinally movable manner, are separated from each other fluid-tight at least in one of the two directions of movement of the pump piston. Each pump chamber () is assigned a valve () opening or closing oppositely to the other valve () when the pump device () is actuated.

Filter device having a pump

A filter device has at least one filter element () accommodated in a filter housing fluid-connected to a fluid tank (). The filter housing has at least one connection fitting () forming a fluid connection to the filter element (). The filter housing is formed by a filter bowl () molded into the tank (). The bowl bottom () has the connection fitting () associated with the element receiver.

Filter device

A filter device, in particular for fluids contaminated with water admixtures, such as diesel oil, has a filter housing () holding at least one filter element (). The filter medium of the filter element separates an untreated side () from a treated side () during the filtration process in the filter housing (). A water collecting unit () is provided and holds separated water on the untreated side. Water separated on the untreated side () also reaches the collecting unit (). Mutually separated collecting chambers () are present in the collecting unit () for the water discharged at the treated side () and at the untreated side ().
