<p>PCT No. PCT/DE90/00173 Sec. 371 Date Feb. 27, 1991 Sec. 102(e) Date Feb. 27, 1991 PCT Filed Mar. 9, 1990 PCT Pub. No. WO91/01445 PCT Pub. Date Feb. 7, 1991.The control device enables an electrically triggered steering wheel key top and, in electronically controlled fuel injection pumps, provides a redundantly acting safety stopping device. For this purpose a 2/2-way valve is used as magnet valve (19), its switching state being determined by the position of the steering wheel key on the one hand and by a switching contact (16) of a diesel engine control device (17) on the other hand. The magnet valve (19) control the flow of engine lubricating oil to an operating piston (28) which can displace a control rod of the fuel injection pump, which controls the quantity of fuel delivered to the internal combustion engine, into its working area. The deflection of the operating piston (28) is influenced by a throttle (42) and a check valve (33), so that the control rod (44), after a stop position "O", automatically arrives in a start position "S" required for restarting the internal combustion engine. This control device is suitable particularly in fuel injection pumps for diesel internal combustion engines.</p> |
