Title: Pressure operated fuel injector nozzle - has two injector needle valves to give stratified charge
IPC: F02M45/08
Filed: 1976-09-10
Abstract: The fuel nozzle contains two injector needle valves (17, 18) actuated by fuel pressure (19). The needle is raised when the fuel pressure is sufficient to overcome the spring pressure (24) which holds the needle valve on to its seat (14, 15). The opposite ends from the valve seats are of reduced diameter it project through holes in the valve body. The ends are ball-shaped to engage with a compensator lever (21). The opposite side of the compensator has a recess for the spherical end of a push rod (22) against which the valve return spring (24) presses. The injector heedles are of unequal diameter. Fuel pressure consequently acts first upon the needle (17) having the greater diameter. The compensator level allows the needle to rise independently to the second needle. Alternatively the needle valves could have equal cross sections. The longitudinal push rod axis (x, y) is different to permit one valve to lift before the second valve.

Title: Motor servo control system - uses integration decision circuit which produces blocking signals for saturation of high and low positive and negative difference signals
Inventor: GAUTHIER ALAIN
IPC: G05D3/14
Filed: 1977-02-18
Abstract: The servo control system has an integral channel for controlling an operation element (8) for regulating a process (8, 4) of which a variable "final" state is represented by a signal (M, I). A "limited variation" variable state must not exceed a "permitted" interval between a high and a low limit. The servo system controls the operation element (8) by using an actuating signal (A) so that the measuring signal (M, I) approaches as closely as possible a level signal (C), (R) furnished by the element (8). The control system has a blocking signal producing circuit. This circuit includes an integration blocking decision circuit. The latter receives high and low level saturation signals and a difference signal (EC). The decision circuit produces the integration blocking signal in two cases. The first (second) cases respectively are when the decision circuit simultaneously receives a high (low) saturation signal and a positive (negative) difference signal.
