Method and apparatus for controlling a solenoid actuated inlet valve of a fuel pump

A method and apparatus for controlling a solenoid actuated inlet valve to a pump chamber of a piston pump. A control circuit 112 energizes the solenoid 116 to open the inlet valve 104 in synchronism with the reciprocation of the piston 108 and thereafter de-energize the solenoid 116 to initiate closure of the inlet valve 104. The inlet valve 104 is decelerated following de-energization of the solenoid 116 thus effectively reducing engine noise attributable to the inlet valve 104.
