ABSTRACT:
A fuel injection pump for internal combustion engines with the injection pump including a dual-acting check valve arranged between the pump cylinder and a valve holder of the injection pump. The check valve is constituted by a resilient valve disk which includes a central passage. A base plate, provided with inlet bores and a central throttle acting in a direction opposite a fuel conveying direction of the injection pump, is arranged between the pump cylinder and the valve holder. The base plate forms an abutment for the valve disk when the check valve opens in a direction opposite the fuel conveying direction of the injection pump.
