Abstract: A single V-shaped tube (1) is bent in a plane and has an inlet section (11), an outlet section (12), an inlet bend (13), an outlet bend (14); a vertex bend (15) and a respective tube section (16, 17) between the inlet bend and the outlet bend. The distance between the vertex of the vertex bend and the inlet/outlet axis can be great. Two clamping bodies (2, 3) are clamped onto the tube sections defining a tube section. Flat bodies (31, 32) are fixed onto the clamping bodies (2, 3). Fixed to the flat bodies is an opposed-action body (41) which extends along the axis of symmetry (I—I) up to the vertex bend, where it supports a first portion of an exciter assembly (50) or a seismic exciter (50′) which excites the tube section in a third mode of vibration at an associated natural frequency f3. A sensor support (61) and a sensor support (62) are fixed to the flat body (31). A velocity or displacement sensor (71, 72) is fixed to the tube section and the sensor supports.

Abstract: A fuel injection system has a low-pressure pump for withdrawing fuel from a tank and a high-pressure pump, which is supplied by the low-pressure pump and has camshaft-actuated pump elements. An on-off valve is connected on the inlet side to the pressure side of the low-pressure pump and on the outlet side, is connected on the one hand to a camshaft chamber of the high-pressure pump and on the other hand, is connected to the suction side of the low-pressure pump. At a first pressure threshold, a spring-loaded valve piston of the on-off valve opens a connection between the low-pressure pump and the camshaft chamber and at a relatively higher second pressure threshold, opens a connection between the pressure side and the suction side of the low-pressure pump. A throttle bore in the bottom of the valve piston serves to ventilate the low-pressure system.

The exterior surface of the titanium cylindrical end forms a joint with the unplated interior surface of the stainless steel sleeve.

Abstract: Surprisingly, silver-copper-palladium brazing alloys, which have hitherto been used only for the brazing of components of the same material, are also very well suited for brazing directly titanium to stainless steel if, the latter component clasps the titanium component tightly, so that the cold joint is under constant compressive stress. In a method for forming the titanium-steel compound the titanium component is provided with a cylindrical end which has a smaller outside diameter than an adjacent main portion whose external surface is a first surface to be brazed. The cylindrical steel component is a sleeve whose inside diameter is equal to the outside diameter of the main portion and whose internal surface is a second surface to be brazed. A silver-copper-palladium brazing alloy is placed around the end of the titanium component. The steel sleeve is slipped thereover.
