Inventor: MENNESSON ANDRE LOUIS
IPC: F02D9/00
Filed: 1958-10-30
Abstract: 871,062. Fluid-pressure servomotor control systems. SOC. INDUSTRIELLE DE BREVETO ET D'ETUDES. Oct. 30, 1958 [Dec. 4, 1957], No. 34880/58. Class 135. [Also in Groups XXVI and XXVII] A speed-regulating device for an I.C. engine wherein a restoring spring 24 acts on the conventional throttle valve member 23 for throttling the air or air-fuel mixture admitted to the engine, is responsive to the pressure of a liquid, preferably the engine fuel, which varies in the same sense as the engine speed, the device comprising a variable-volume chamber 13 wherein the liquid is introduced through a first orifice 15 and discharged through a second orifice 18, and a mobile or deformable member e.g. a diaphragm 11 carrying a needle valve 16 in the chamber is displaced by the liquid pressure against the spring 24, the device being characterized in that the mobile or deformable member increases the cross-section of the inlet orifice and/or decrease the cross-section of the outlet orifice, and consequently increases the pressure in the chamber 13, in proportion as the tension of the restoring spring increases, in such manner that regulation commences at substantially the same speed irrespective of the engine load i.e. irrespective of the opening of the throttle member. As further shown, the throttle is carried by a lever 22 abutted in the'.closing direction by a rod 20 carried by the diaphragm 11, the throttle being normally opened against the spring by a lever 27 carrying a pin 26 which abuts the lever 22 in the reverse direction. A feed pump P delivers fuel through a pipe 10 to the eye of an engine driven centrifugal impeller 2 having a closed periphery and adapted to pressurize an annular volume of fuel therein as a function of engine speed, any surplus fuel draining out of the impeller eye being returned to the feed pump via a float device 9. Astationary pick-up member in the impeller leads the pressurized fuel into a conduit 7 whence some is taken through a conduit 7a for delivery to the engine and the remainder through a pipe 14 to the inlet orifice 15 of chamber 13. An open pipe 19.drains this chamber in the event of rupture of the diaphragm. Where it is desired to regulate the engine of a vehicle only when it is engaged in top gear, an isolating cock 29 in the pipe 14 is arranged to remain closed so long as the top gear has not been engaged. Specification 843,427 is referred to in connection with a separate diaphragm pump 36 which may be cam-operated from the impeller shaft 1.

A fuel-injection pump comprises a reciprocating and rotating piston 4 drawing fuel from an inlet chamber 6 via passages 8 and 10, and delivering the fuel to outlet passages 12 via distributer groove 11, delivery being regulated according to engine speed by a by-pass valve 13 in a by-pass 14, 16 valve 13 being actuated by an auxiliary pump piston 5 supplying liquid via a throttle valve 23 which is moved against a spring 29 by the auxiliary pump pressure to open the throttle passage 22 during the right-ward movement of by-pass valve 13, and is moved into its throttling position by the spring during the left-ward movement of valve 13 to brake this movement on the "hydraulic stop" principle. Valve 23 has a helical surface 31 so that rotation of the valve adjusts the throttle crosssection. In the embodiment of Fig. 2 (not shown), the throttle valve (24) is spring-loaded against a stop which is adjustable to vary the throttle cross-section, and an additional fixed adjustable throttle (36b) is provided to prevent racing of the engine if throttle valve (24) jams open. A passage 34 communicating with the fuel tank limits the rightward movement of by-pass valve 13 and withdraws fuel impurities passing beyond throttle 22.
