Abstract

1,200,041. Fluid-pressure servomotor systems. ROBERT BOSCH G.m.b.H. Jan.2, 1969 [Jan.5, 1968], No.179/69. Heading G3P. [Also in Division F1] In an I.C. engine fuel injection system (see Division F1) changes in the static pressure at a variable flow cross section 17 act in chamber 31a and the pressure downstream of the section 17 acts in chamber 31b. The resultant pressure differential acting on a spring-loaded diaphragm 30 moves a valve spool 29 to admit pressure fuel to a chamber 23. The spring-loaded piston 16 and regulating member 2 are moved upstream to reduce section 17. Simultaneously cam 18 moves the pin 19 to reduce the fuel supply to nozzles 12. Similarly when the static pressure at 17 decreases the regulating member 2 is moved to increase section 17 and the fuel supply to nozzles 12.
