Title: Supporting bow for a folding top of a vehicle
Inventor: GUCKEL MARTIN DIPL ING
IPC: B60J7/12
Filed: 1993-07-21
Abstract: The invention relates to a supporting bow for a folding top (soft top) of a vehicle, in particular a corner strut which, for the purpose of tensioning a folding-top cloth secured on the front and rear edge, can be moved up into a tensioning position acting upon the folding-top cloth, the supporting bow, which is mounted on its lateral limbs, being transferable into its tensioning position by means of two operating elements which can be changed in length axially, and the operating elements, which are arranged mirror-symmetrically on opposite sides of the vehicle, cooperating with that limb of the supporting bow which is assigned to them. In order for it to be possible for the operating elements to be arranged relatively flexibly and for problem-free, safe operation of the corner strut to be possible, hydraulic cylinders which operate synchronously are provided as operating elements.
Patent DE-4328989-A1 (DE)
Title: Diaphragm carburettor
Inventor: BENHOLZ MARTIN DIPL ING
IPC: F02M17/04
Filed: 1993-08-28
Abstract: Diaphragm carburettor for varying the air/fuel ratio. In devices of this type hitherto known the engine speed, on attainment of a certain limit, is indirectly controlled by enrichment of the mixture in that action is exerted on a control diaphragm by means of excess pressure or by a solenoid, so that a valve needle is opened by a lever mechanism allowing increased enrichment of the air/fuel mixture. With the device according to the invention the same result is obtained by a simpler and more compact design with less sensitivity to wear and faults and improved controllability. In the carburettor, a coil is arranged around a valve needle so that the coil together with the valve needle forms a solenoid, the valve needle being the armature of the magnet. On attainment of an engine speed limit the coil is activated by a current and the armature also raised, thereby permitting an increased fuel feed flow. The enrichment of the air/fuel mixture thereby achieved limits the engine speed. Diaphragm carburettor with variation of the air/fuel ratio for an internal combustion engine of a power tool, especially power saws, hedge shears and the like.
