Abstract

1500291 Fuel injection apparatus for IC engines WISSENSCHAFTLICH-TECHNISCHES ZENTRUM AUTOMOBILBAK KARL-MARX-STADT VEB 3 July 1975 [8 July 1974] 27999/75 Heading F1B An arrangement for injecting fuel comprises a fuel injection valve 4 having a needle 202 displaceable between closed and open positions and being biased towards its closed position when a pressure fluid is applied to a piston element 21 from a source 1 via an electromagnetic control valve 3 and a control conduit 211 and being biased towards its open position when the control conduit 211 is placed in communication with a pressure relief duct R 2 by the valve 3. The pressure fluid (fuel) is supplied from source 1 to a pressure store 14 by a pump 12. In Fig. 2 (not shown) is a detail of the control valve 3 with a control member (312), the frusto-conical part of which includes an angle α in the range 60 degrees to 180 degrees but excluding the value 90 degrees.
