Abstract: A fuel tank for receiving a fluid in a motor vehicle. The fuel tank includes an outer wall forming an internal space for receiving the fluid. At least one volume element is arranged in the internal space for receiving air, and an opening that is a gas-guiding line between the volume element and the environment of the tank is for changing the volume of the volume element. The at least one volume element is formed at least partially as bellows.

Abstract: The invention relates to a device (6) for pressure-dependent opening of a suction intake (10), comprising a suction jet pump (11), comprising a feed line (12), an outlet line (13) and the suction intake (10); a valve body (15), displaceably arranged inside the feed line (12) in the delivery direction (14) of the suction jet pump (11) and having an effective area (16) exposed to the feed pressure of the suction jet pump (11); and a spring element (17), arranged between the feed line (12) and the valve body (15), for applying a force in opposition to the feed pressure inside the feed line (12); wherein the effective area (16) of the valve body (15), and the spring element (17) are designed so that the valve body (15) closes the suction intake (10) so that it is fluid-tight below a predefined pressure inside the feed line (12) and opens said intake when the predefined pressure inside the feed line (12) is exceeded.

Abstract: The invention relates to an earthing element for the filler pipe of a motor vehicle, and also to a mouthpiece on a filler pipe of a motor vehicle. The earthing element is in the form of an earthing strap (7) which is composed of an electrically conductive polymer.

Abstract: A device for fixing a functional component within a fuel tank that makes use of an opening in the tank wall of the fuel tank. The device comprises at least one connecting element for receiving the functional component, with the connecting element being latched in an opening in the tank body wall, in a position of passing therethrough. The opening is sealingly closed at the outside of the tank by a closure member or a cover cap or a connection portion can be fitted to the opening for the connection thereto of a device intended to communicate with the tank interior.
