Title:
LIQUID FUEL SUPPLY PUMP
Document Type and Number:
WIPO Patent Application WO/1981/003363
Kind Code:
A1
Abstract:
A liquid fuel supply pump which has a stationary member (2) and a rotary member (1) with a shallow spiral groove pattern (14) formed in on at least one of the confronting surfaces thereof so that liquid fuel (17) is fed under pressure through the pattern (14). A fluid bearing for the rotary member (1) is formed by the liquid fuel (17) flowing through the gap between the stationary member (2) and the rotary member (1). The gap formed therebetween is constructed to be less than 20 microns, thereby stably supplying the liquid fuel (17) at an infinitesimal flow rate to a liquid fuel combustion device in the liquid fuel supply pump.
