Abstract:
The invention relates to a plastic fuel tank (1) for motor vehicles having at least one tank wall (2) surrounding at least one fuel volume, wherein the tank wall (2) is provided at least in a certain area or certain areas with means for increasing flexural rigidity in the form of two-dimensionally extended reinforcing layers (3) connected materially and/or positively thereto (FIG. 1).
Abstract:
The invention relates to a device for forming moulded bodies from a mouldable mass comprising a matrix grid (19) in which at least one receiving chamber (21) is accommodated, and at least one tool (17, 18) with which the mouldable mass can be pressed into the receiving chamber (21). Said claimed device is characterised in that the tool (17, 18) can be displaced along a guide path (3A, 3B) that comprises a moulding section (A), in which a constant pressure is exerted upon portions of the mouldable mass on the strip by the tools (17, 18), said mass being disposed in the receiving chamber (21). The invention further relates to a method for forming moulded bodies, in which a mouldable mass is formed and is guided to at least one receiving chamber of a matrix grid (1). At least one tool (17, 18) then presses one portion of the mouldable mass into the receiving chamber (21), in which the tool (17, 18) is displaced along a guide path (3) that comprises a moulding section (A), wherein a constant pressure is exerted upon the portions of the mouldable mass on the strip by the tools (17, 18), said portions being disposed in the receiving chamber (21).
Abstract:
The invention relates to a motor vehicle fuel tank (1) of thermoplastics having at least one filler neck (4) not moulded on in one piece, the latter being connected in a fluid-tight manner to the fuel tank (4), wherein the filler neck (5) is inserted into an opening (5) in the fuel tank (1) and is sealed by sealing means (11) at its outer circumference relative to the fuel tank (1) in the opening (5). The filler neck (4) is clamped axially against the tank wall (2), with the seal acting radially.
Abstract:
The invention relates to a thermoplastic fuel tank (1) for motor vehicles, with at least on stiffening element within the fuel tank (1), wherein the stiffening element extends between two opposite tank walls (4) in such a manner that it counteracts deformation caused by internal pressure of the fuel tank (1). According to the invention, two ends of the stiffening element arranged within the fuel tank (1) engage behind the tank wall (4) from the outside.
Abstract:
The invention concerns a process for the production of an article enclosing built-in fitment components in the form of a hollow body of thermoplastic material. The hollow body is preferably in the form of a fuel tank. The process includes the extrusion of one or more preforms in web or tube form of plasticized material between the opened portions of a mold tool forming a cavity, wherein at least one built-in fitment component to be enclosed by the finished article is placed between the portions of the mold tool and the tool is closed around the preforms and the built-in fitment component, wherein the preforms within the cavity enclosed by the tool acquire the external configuration of the article. The built-in fitment component is pressed during or directly after the shaping operation against the inside wall of the article while still plastic so that the plastic material of the hollow body penetrates through at least one recess or opening of the built-in fitment component and flows therebehind.
Abstract:
The invention concerns a fuel tank (1) of thermoplastic material, comprising functional installation fitments for air intake and venting, for fuel take-off or the like, which is distinguished in that at least one functional installation fitment is connected to the inside wall (3) of the container in material-bonded relationship in such a way that the functional installation fitment defines with the container wall a volume separated from the filling volume of the container in such a way that the inside wall (3) of the container serves directly as a boundary wall of said volume.

Abstract:
The invention concerns a fuel tank for a motor vehicle, comprising at least one venting device which is connected to a fuel vapor filter, wherein the venting device includes at least one collecting container (4) for receiving liquid fuel (21). The fuel tank is distinguished in that disposed within the collecting container (4) is a delivery pump (8) for emptying it into the delivery volume (23) of the fuel tank (1).
Abstract:
A locating device for vehicles with a carrier to be mounted in the vehicle in which a gyro-sensor is located to detect the movement of moving components for the purpose of determining the location. As gyro-sensors must be oriented a certain way in order to fulfill their function, and as this orientation is not possible in all installation locations, the invention is the result of the task of specifying a gyro-sensor that can be used regardless of the corresponding mounting situation, where the corresponding sensor (gyro-sensor) can be oriented at the installation location and manufactured using automated manufacturing processes and where special securing devices are not required to secure the unit in the aligned position. This task is accomplished in that there are complementary tabs and notches located on the gyro-sensor and on the housing in which the gyro-sensor is inserted that permit the gyro-sensor to be mounted in the housing in at least two different positions, and/or that the housing with its casing shell surface is installed in a holding device, where the housing can be installed in the holding device in at least one prescribed position.
