Japanese Patent JPS5198427
Kind Code:
A
Abstract:
A fuel injection pump for internal combustion engines has a simultaneously reciprocating and rotating pump piston which aspirates fuel from a fuel compartment and then delivers it under pressure to engine fuel lines. An electromagnetic valve can obturate the conduit between the fuel compartment and the pressure chamber of the pump, thereby shutting off fuel delivery. To permit manual override of this shut-off, the electromagnetic valve may be partially unscrewed from the pump housing, thereby lifting the valve closing member from its seat and permitting fuel flow. In another version, an externally accessible central valve bolt partially lifts the valve-closing member from its seat.
