A device for detection of a defined relative position of a first, movable means, relatively a second, fixed means and including a sensor (1) arranged at least at one of the first and second means which sensor is provided with a pressure sensing means (CC.sub.M). The sensor (1) gives rise to an electric detector signal, which indicates whether the defined relative position has been taken. The sensor (1) is also provided with a closed cavity (13) which communicates with a pressure sensing means (C.sub.M) and with means (14/36/45) to momentarily limit the volume of the cavity and thereby create a pressure pulse adapted to activate the pressure sensing means of the sensor. The detector device includes means to convert the pressure pulse to a detection signal to detect the defined relative position.

Fuel meter for vehicles

A device in a fuel tank for motor vehicles which, if the fuel level is low when driving on an inclined surface, retains a required amount of fuel around the fuel line opening to prevent air intake. Around a container on the tank bottom, into which the fuel line opens, is a larger container, and the two containers have inlets for fuel from the surrounding tank. One container has the inlet in its front side wall and the other container in its rear side wall, as viewed in the longitudinal direction of the vehicle.
