Abstract: A fuel tank that includes a fuel container, a filler pipe, a connecting piece member, and an annular locking element. The connecting piece member is configured to connect the filler pipe to the fuel container, and is a substantially cylindrical sheet metal shaped cross-section having a first connecting end for fastening to a first component to be connected, and a second connecting end for receipt in a second component to be connected. The second connecting end has a first portion with a first groove shaped therein. The annular locking element extends at least partially through openings of the second component to be connected at a connection point into an interior of the second component to be connected, and at the connection point, axially secures the second component to be connected relative to the connecting piece member by a positive connection on the first groove.

Abstract: A ventilation device for ventilating a motor vehicle tank. The ventilation device includes a filler pipe, a ventilation line, a degassing line, and a guide arc member. The ventilation line is to be fluidically connected at a first ventilation line end to the motor vehicle tank, and at a second ventilation line end to the filler pipe via a ventilation inlet. The degassing line is to be fluidically connected at a first degassing line end to the filler pipe via a degassing outlet. The guide arc member is arranged in the filler pipe to define a guide path for incoming vapor passing through the ventilation inlet into the filler pipe. The guide arc member is to facilitate flow of the incoming vapor between an inner wall of the filler pipe and the guide arc member along a periphery of the filler pipe along a periphery of the filler pipe such that a gaseous component of the incoming vapor escapes through the degassing outlet and a liquid component of the incoming vapor flows off through the filler pipe.

Abstract: A venting device for venting a motor vehicle tank that includes a filling pipe, a venting line, a degassing line, and a connection nipple. The venting line is for fluidic connection at a first venting line end to the motor vehicle tank, and at a second venting line end opposite the first venting line end to the filling pipe via a venting inlet. The degassing line is for fluidic connection at a first degassing line end to the filling pipe via a degassing outlet, and at a second degassing line end opposite the first degassing line end to a liquid separator. The connection nipple is arranged on the filling pipe upon which the venting inlet and the degassing outlet are constructed.

Abstract: A separation nipple to separate a liquid from a vent inlet line into a filler pipe of a motor vehicle. The separation nipple has an inlet for connection to the vent inlet line, an outlet for connection to a vent outlet line, an opening for connection to an interior of the filler pipe, and a flap to close the opening. The flap has a main flap surface and a reflector flap surface which slopes relative to the main flap surface. The reflector flap surface is configured to form a reflector with the main flap surface when the flap is in an open position, the reflector being configured to deflect liquid passing through the opening in a direction of an end of the tank of the filler pipe. The opening is configured for closing by the main flap surface when the flap is in a closed position.

Abstract: A siphoning-off guard for a motor vehicle tank system that includes a filler pipe head, a tube and a motor vehicle tank, the motor vehicle tank system contains components which form an end region, the siphoning-off guard being fastened to the end region on the outside surface of the component.

Abstract: A filler head for a fuel filler pipe that includes a housing and a flow guide configured in one piece from metal.

Abstract: A device for protection against incorrect refuelling, the device including a housing having housing tabs, a separating element to be opened to permit refuelling, and a closing element arranged in, and axially moveable axially relative to the housing. The closing element has at a periphery thereof closing tabs assigned to the housing tabs to form a catch connection which is reversibly released by insertion of a suitable filler nozzle to open the separating element.

Abstract: A tank system which prevents problems caused by electrostatic charging during a fueling sequence. The tank system includes a filling pipe, a filling hose which leads to a fuel tank, and a support sleeve, composed of an electrically conductive plastic material, in abutment with the filling pipe and the filling hose to thereby connect the filling pipe to the filling hose in an electrically conductive manner.

Abstract: A filling device for a metal tank, the filling device including a filler pipe composed of a polymer, and a coupling element composed of a metal to connect the filler pipe to the metal tank, the coupling element having a first connection portion upon which the filler pipe is shrink-fitted and a second connection portion to fasten the coupling element to the metal tank.

Abstract: A filler neck for the fuel tank of a motor vehicle has a funnel insert having a lockable flap with a lock, which is held by two elements which can each be pivoted about a pin. The flap is released only when both elements are pivoted to one side simultaneously by the filler tube of a gas pump nozzle. In order to open the flap with minimal actuating forces, the first element can be pivoted about a first pin and holds the hinge pin for the flap on its end far from the first pin, and the second element can be pivoted about a second pin and forms a locking hook. The two pins have a spatial distance from one another in the transverse direction and the two elements are loaded with respect to one another by at least one spring.
