Electromagnetic valve for fluid flow control
 A fuel injector valve for use in an internal combustion engine has a spherical valve member which is movable to be biased onto a valve seat by pressure differential between upstream and downstream sides of the valve member. A pressure responsive element is disposed within the electromagnetic valve and located opposite to the valve member in order to bias the valve member against the valve seat to close a fuel outlet when fuel pressure prevailing upstream of the valve member is lower than a predetermined level.
