Abstract
The electromagnetic valve for use in a high pressure fuel supply apparatus includes an electromagnetic valve main body including a fuel passage to be connected between the high and low pressure sides of the fuel supply apparatus, a valve seat disposed in the fuel passage, a valve member disposed within the electromagnetic valve main body in such a manner that it is detached from and contacted with the valve seat to thereby open and close the fuel passage, and a solenoid coil for moving the valve member with respect to the valve seat. The electromagnetic valve is capable of maintaining the jet-out quantity of the fuel from the high pressure fuel supply apparatus at a given value.
Claims4
An electromagnetic valve for a high pressure fuel supply apparatus, comprising:
- an electromagnetic valve main body including a fuel passage to be connected between a high and a low pressure sides of said high pressure fuel supply apparatus;
- a valve seat disposed in said fuel passage;
- a valve member disposed within said electromagnetic valve main body so as to be detached from and contacted with said valve seat to open and close said fuel passage;
- and
- a solenoid coil for moving said valve member with respect to said valve seat in such a manner that a jet-out quantity of the fuel from said high pressure fuel supply apparatus is maintained at a given value, wherein
- said valve seat includes an inclined surface having a given angle with respect to the moving direction of said valve member, and
- said valve member has an R shape in the portion thereof which, when said valve member is closed, is capable to be contacted with said inclined surface of said valve seat.
