PURPOSE:To compensate uneven characteristic of injection amount simply by providing adjustment elements for the compensation of the characteristic of injection amount in the first connector unit and connecting them to a control unit via the second connector. CONSTITUTION:One ends of variable resistances 16 and 17 are connected with each other in a connector 12, and connected to an earthing line 15a in a cable 15 via a connector 13. Their other ends are respectively connected to one ends of resistances 18 and 19 respectively connected in other ends to an electric source +V via wires 15b and 15c, and voltages V1 and V2 on both ends of resistances 16 and 17 are respectively added to a control circuit 20 in a control unit 3. In this construction, wirings of variable resistances 16 and 17 of adjustment elements are arranged independently of other wirings in cables 14 and 15. The adjustment of their resistance values allows to compensate the control characteristic of injection amount in accordance with values of voltages V1 and V2 added to the circuit 20. |
