core 28 is provided with an axial through-hole as a fuel
passage 25. A compression spring 26 is inserted into the
front portion of the axial through-hole so as to normally bias
against the rear end of the valve body 31 and hold the valve
body 31 in a closed position. The compression spring 26 abuts
against the front end of a sleeve 25a which is carried in the
axial through-hole of the fixed magnet core 28. As shown in
Figure 4, the valve body 31 is constituted of a valve member
32 having a spherical surface 32a, hollow cylindrical slide
member 33 and an armature 34 fixed on the rear end of the
slide member 33. The interior of the slide member 33 serves
as a fuel passage 33a and fuel outlets 33b are provided at the
front side wall of the slide member 33. With this
arrangement, liquid fuel flowing through an opening 34a of the
armature 34 is supplied through the fuel passage 33a and the
fuel outputs 33b to the fuel chamber 24a. In order to reduce
the weight of the valve body 31, the valve member 32 and/or
the slide member 33 are preferably formed of titanium or
titanium alloy having specific gravity of about 4.5 as well as
stainless steel SUS 440C having specific gravity of about 8.0
