  • Pump for supplying liquid fuel
    Patent number: 4470752
    Abstract: 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.
