PCT No. PCT/JP81/00110 Sec. 371 Date Jan. 11, 1982 Sec. 102(e) Date Jan. 11, 1982 PCT Filed May 14, 1981 PCT Pub. No. WO81/03363 PCT Pub. Date Nov. 26, 1981.This invention relates to a liquid fuel supply pump which has a pattern of shallow grooves 14 formed on at least one of the opposed surfaces of a stationary member 2 and a rotary member 1 to forcibly send liquid fuel 17 forward by the groove pattern 14. A fluid bearing is formed for the rotary member 1 by the liquid fuel 17 flowing through a clearance between the stationary member 2 and the rotary member 1, and the clearance is made not larger than 20 microns, whereby the liquid fuel supply pump is adapted to supply the liquid fuel 17 to a liquid fuel combustion apparatus stably at an exceedingly low flow rate.
