Filed: 1994-02-03
Abstract: In the production of a tube by means of electrical resistance welding involving the deformation of a steel strip into a tubular form and welding of the edges, a stand or the like has to be changed when the diameter of the tube changes. In this arrangement, a drive-side stand (1) is mounted on a main support (8) and an operating-side stand (2) is mounted on an auxiliary support (7), and the auxiliary support (7) is arranged on the main support (8) in a manner which allows it to be displaced and fixed. To change the stand, the auxiliary support (7) and the operating-side stand (2) are displaced and the roll (4) and the roll shaft (3) are removed together with the operating-side stand (2) and the auxiliary support (7) from the main support (8) and the drive-side stand (1) to allow them to be raised by means of a crane. With the arrangement according to the invention, the number of parts to be changed is reduced by half in comparison with known arrangements, and the investment required is reduced. The amount of work required to change a roll outside the production line is reduced by more than 80% and the roll can be changed on the stand in 10 to 15 minutes. A holding unit for an intermediate shaft (18) serves at the same time as a drive-side stand (1), thereby reducing the number of components. <IMAGE>

Patent DE-4436416-A1 (DE)
Inventor: HABERLAND SIEGFRIED
IPC: F02M41/12
Filed: 1994-10-12
Abstract: The invention concerns a fuel injection pump having an annular slide valve (20) which can be displaced on the pump piston by means of a control device and which has a guiding edge by means of which a pressure-relief duct in the pump working chamber can be opened during the delivery stroke of the pump piston. The pressure relief duct part projecting from the generated surface of the pump piston is in the form of a radial bore (18) and the fuel jet discharged therefrom is deflected by a deflection surface (34) on the annular slide valve or a deflection surface (76) on the pump piston such that the jet is deflected out of the radial plane so avoiding pressure zones acting in an axial direction and different axial loads on the control valve owing to the successive individual intake control processes. In this way fluctuations in the amount of fuel injected from one injection process to the next and the load on the control device parts are also reduced.
