摘要:
A method for filling a vehicle fuel tank with a gas is provided, in which the vehicle fuel tank (31) is connected to a delivery device (2) by a pressure-tight line (10) and the gas stored under pressure is filled into the vehicle fuel tank (31) from a storage unit (3) by means of the delivery device (2). The method comprises the following steps: the instantaneous value of a parameter, which is representative of the instantaneous level of filling of the vehicle fuel tank (31), is determined during filling with the aid of a sensor apparatus (32, 33) arranged in the vehicle fuel tank (31) the filling is ended when the parameter has reached a pre-settable end value.

A pressure limiting valve includes an inlet and an outlet for a fluid, which includes a valve body which cooperates with a valve seat in such a manner that it opens or closes a flow connection for the fluid between the inlet and the outlet when a limiting pressure is reached. The valve also includes a spring element which acts on the valve body and loads the latter. A container for a liquid is provided which is arranged and designed in such a manner that through its thermal expansion, the liquid varies the loading of the valve body which is caused by the spring element, and thus varies the limiting pressure in dependence on the temperature of the liquid.

The invention embraces a method of tanking or filling of motor vehicles with natural gas and also an apparatus for operating the method of the invention. The motor vehicle includes a tank apparatus (2) with a pressure container (19). A tanking plant (1) includes a storage unit (3) for natural gas, a delivery device (5) and also a connection line (14) which can be connected to the tank device (2). The delivery device (5) includes a control and measuring device (5a), a regulating device (5b) and also an input and output device (5c). The control and measuring device (5a) has a regulating valve (7), a mass throughflow measuring device (8) and also a pressure sensor (9), with these three components being so controlled from the governing regulating device (5b) that the pressure container (19) is filled in a short period of time with natural gas.

The vessel comprises a part having an end portion which is introducible into a second vessel part and which has a cylindrical outside surface formed with an annular recess. The second vessel part has a connecting part having a cylindrical inside surface formed with a recess in the form of an annular groove and having a connecting duct which extends from the outside into the recess tangentially. When the two casing parts are in a connected position the two recesses bound a guide duct for a flexible closure part which is made, for example, of a steel string or cord or the like and which is introduced through the connecting duct into the guide duct to interconnect the two casing parts and withdrawn from the guide duct to release the two casing parts (1, 1a, 2a). The vessel is of use, particularly in association with a facility for filling a gas fuel tank, as a pressure-resistant casing for control and/or switching elements and can be opened with reduced manual intervention for the inspection and servicing of the latter components and closed reliably.

An actuating system for a bobbin tube gripper comprises resilient structure held in compression in order to create a force for urging tube gripping elements into engagement with a tube to be gripped. The resilient structure constitutes a body of a porous elastomer.
