HEAT CONTROLLED FUEL SUPPLY SYSTEM FOR DIESEL Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: system has fuel tank 1, pumping pump 2, fuel filter 3, pipe lines 4,5,6, high pressure fuel pump 7 with pickup-temperature-sensitive- resistor 8 mounted at the inlet, electromagnet 13 with armature 15 and amplifier 12 built-in under cover 14 of electromagnet 13, and housing 16 of a switch with three- linear valve of by-passing fuel constructed as cylindric collar 29 with four by-pass openings and rod 28 which is screwed in armature 15 spring-loaded by spring 25. Two radial and central openings are made in housing 16. The distance between axes of two radial openings is equal to the height of collar 29 and is 1.5 times grater than the diameter of the working openings. The total area of cross-section of the by-pass openings are equal to the area of the working opening. EFFECT: enhanced reliability. 2 cl, 4 dwg
