Abstract

1292219 Fluid-pressure servomotor systems ROBERT BOSCH GmbH 26 Feb 1970 [27 Feb 1969] 9217/70 Heading G3P A hydraulic governor for an I.C. engine fuel injection pump comprises an engine driven pump 1 whose delivery pressure acts on an element 10 which influences the quantity of fuel injected. A valve 5 in series with an adjustable throttle valve 19 inter-connects the two sides of the pump and the piston 13 normally allows an approximately linear increase in pump output pressure with speed while the throttle valve superimposes a quadradic variation to reduce to speed droop. A maximum pressure valve 6 is in parallel with the valve 5 and throttle valve 19 and a second piston valve 22 controls the position of an element 25 which influences the commencement of injection.
