Title (EN) CENTRIFUGAL-FORCE SPEED REGULATOR FOR INTERNAL COMBUSTION ENGINES
(FR) REGULATEUR DE VITESSE CENTRIFUGE POUR MOTEURS A COMBUSTION INTERNE
Abstract:
(EN) Idling and final speed regulator for internal combustion engines with a centrifugal-weight regulator (4) serving to adjust the idling and final-speed and producing, against the force of adjuster springs (8), a setting power corresponding to the rotation speed of the engine, provided with a coupling (9) located between an adjuster rod (3) serving to control the quantity and the centrifugal weight regulator (4), with a regulating sleeve (7) having a drag-link, and with a shackle (13) between an intermediate lever (12) belonging to the coupling (9) and the adjuster rod (3). The shackle (13) is provided with a slide (26) which can be slid in a quantity-adjusting direction, said slide (26) being loaded by a starting spring (27) in the direction of an increase in injection quantity and working in co-operation with a total load stop (32), which is per se stationary, but can be varied as a function of characteristic operating values, for example, by a loading pressure adjuster (33), this variation of the stop position signifying a change in the adjustment travel, which is compensated by a deviation travel (A) of the drag-link (14) in the regulating sleeve (7).
(FR) Régulateur de vitesse finale et au ralenti pour moteurs à combustion interne, pourvu d'un régulateur à boule (4) servant à régler la vitesse finale et la vitesse au ralenti et produisant, contre la force de ressort de réglage (8), une puissance de réglage correspondant à la vitesse de rotation du moteur, pourvu également d'un accouplement (9) situé entre une tige de réglage (3) servant à réguler la quantité et le régulateur à boule (4), et comportant un manchon de régulateur (7) muni d'un organe de liaison et une barette (13) entre un levier intermédiaire (12) appartenant à l'accouplement (9) et la tige de réglage (3). La barette (13) possède un coulisseau (26) qui peut être déplacé dans le sens de régulation de la quantité, ledit coulisseau (26) étant chargé par un ressort de lancement (27) dans le sens de l'augmentation de la quantité d'injection et coopérant avec une butée de pleine charge (32), laquelle est fixe en soi mais peut être modifiée en fonction de grandeurs caractéristiques de fonctionnement, par exemple par un régulateur d'admission (33), cette variation de la position de la butée signifiant une modification de la course de réglage, laquelle est compensée par une course de déviation (A) de l'organe de liaison (14) dans le manchon de régulateur (7).
