Abstract
592,833. Fluid-pressure servomotorcontrol systems. LUCAS, Ltd., J., and WATT, J. L. June 1, 1945, No. 13824. [Class 135] The output of a liquid fuel pump, e.g. of the swash. plate type, is controlled by a spring-loaded piston q subject on both sides through a restricted passage tc the outlet pressure of the pump and disposed in a cylinder having an outlet u to a sump or the pump inlet controlled by a pivoted closure v disposed in a chamber 6 having an outlet 7, Fig. 2, to the sump controlled by a pivoted closure 8. By this arrangement, if closure of the outlet u is obstructed, the outlet 7 can be closed to permit functioning of the control. The closure v is carried by an arm 9 fast on a spindle 10 projecting through a wall of the chamber 6 and carrying a second arm 11, while the closure 8 is mounted on a lever 12 supported on pivots 13 coaxial with the spindle 10, the arm 11 and the lever being spring-loaded to hold the closures against their seats. Opening of the closures 8 is effected by a stop 2 on a spring-loaded diaphragm z subject on its outer side to, e.g. the oil pressure in the pump casing b, and on its inner side to the pressure in the oil inlet duct i. The pressure in the casing b is built up by a centrifugal pump formed by the axial and radial passages m, o respectively in the pump body a.
