The governor includes a torque-control capsule actuated by a governor member that adjusts in accordance with rpm and disposed in a force-transmitting member subject to the force of a governor spring, by means of which torque-control capsule both the onset and control stroke (b) of torque control are adjustable or settable in an infinitely graduated manner without affecting one another. The torque-control capsule has a stop bolt inserted in a stepped longitudinal bore of a stop housing, a torque-control spring and an adjusting screw, which forms an abutment for the torque-control spring. The adjusting screw is adjustable in an infinitely graduated manner and is secured in a positionally fixed manner inside the stop housing in the vicinity of an internal thread. By turning the adjusting screw, an infinitely graduated variation of the initial stress of the torque-control spring can be performed, even in the installed state, without affecting the previously set torque-control stroke (b), and by varying the depth of threaded insertion of the torque-control capsule inside the force-transmitting member, the protruding dimension (b) corresponding to the torque-control stroke is adjustable without affecting the initial stress of the torque-control spring.

Centrifugal rpm governor for internal combustion engines

A correction spring capsule which has a stop bolt inserted in a stepped longitudinal bore of a housing embodied as a screw sheath, a correction spring and an adjusting screw, which forms the abutment for the correction spring. This adjusting screw has the form of a cup-shaped adjusting ring provided with a continuous external thread and having a bottom and a sheath-like wall. The sheath-like wall is deformed into an oval shape in order to attain positional fixation of the adjusting screw and has its greatest deformation in the vicinity of one end section that is open toward the outside. As a result, the adjusting screw is infinitely adjustable and is secured in a positionally fixed manner in any position inside the housing in the vicinity of an internal thread.

Correction spring capsule for injection devices of internal combustion

Centrifugal speed governor of fuel injection pumps

A pneumatic diaphragm control element for a fuel injection apparatus for internal combustion engines, in particular for supercharged diesel engines, has a thrust rod that is axially displaceable between two end stop counter to the force of a restoring spring, which thrust rod acts upon a control member of the fuel injection apparatus and is connected to a pressure-actuated diaphragm. One end stop determines the position assumed by the thrust rod when there is no pressure and is embodied as a stop screw for the thrust rod. The second end stop defines the position assumed by the thrust rod with maximal pressure being exerted on the diaphragm, and to this end cooperates with a counterpart stop that is adjustably coupled with the thrust rod. For better adaptation of the regulating characteristic, the counterpart stop is embodied as a pre-stressed spring assembly with two stop positions, such that when the first stop position is attained, after the spring pre-stressing is overcome, a further displacement travel (S.sub.2) of the thrust rod until the second stop position is attained is available.

A speed governor for fuel injection pumps is proposed having a guide shaft guided in a cam plate to serve as the pivot shaft for a governor lever connecting an adjusting member and a supply quantity control member. The guide shaft is adjustable and guided appropriately by means of an adjusting lever so far as to form a variable-speed governor adapted to varying the full-load and maximum rpm. The cam plate is adjustable by a device by means of an operating parameter acting independently of the speed governor, for instance, the engagement of a cruising or overdrive gear in a manual transmission. Upon rotation of the cam plate, the guide shaft is displaced by a movement-coupling member into a position in which a minimum idling rpm is assured.

Speed governor for fuel injection pumps

The governor includes a force transmission lever subject to the prestressing force of a main governor spring, which lever the governor sleeve comes into operative contact after traversing an idling sleeve path a, and a leaf spring acting as the idling spring. The leaf spring is supported between its two ends on a curved rolloff path, determining its effective spring length, of a support bearing, the operative position of which is adjustable toward the leaf spring in accordance with the pivot angle (.beta.) of an adjusting member by means of an adjusting cam actuable by the adjusting member such as to increase the prestressing force of the leaf spring. The adjusting cam is supported on the force transmission lever in order to prevent influencing the maximum engine speed. With the adjusting member shifted from the idling position toward the full-load position, the corresponding governor characteristic curve is shifted, simultaneously with an increased supply quantity controlled by the governor, toward a higher partial-load engine speed, and by means of the spring rate of the leaf spring which changes as the engine runs up to maximum speed, governor characteristic curves are produced which continuously drop exponentially.

Minimum-maximum speed governor for fuel-injected engines

A centrigural rpm governor for fuel injected internal combustion engines is proposed in which an adaptor assembly located inside the governor can be used over the entire range of practical applications of such a governor. The governor includes parallel coextensive arms, a governor lever and a cooperative governor rod which has a counterstop provided with a sliding block that is movably disposed between the parallel coextensive arms against the initial stressing force of a spring member with the counterstop being arranged to cooperate with a stop means pivotally associated with the housing. The spring member is arranged to load the sliding block and adjustable for the purpose of varying the initial stress and setting the onset of adjustment.

Centrifugal RPM governor for fuel injected internal combustion engines

A centrifugal rpm governor for internal combustion engines in which the initial stressing of an adaptation spring is adjustable in a continuously variable manner in the installed state and without changing the spring stroke (b) determining the adaptation path. The governor includes an adaptation device disposed in the force transmitting path between a control member which adjusts in accordance with rpm and a force transmitting member subject to the force of the governor spring, which adaptation device includes in a recessed longitudinal bore, a stop bolt and an adaptation spring supported at one end by a ring screwed onto a threaded portion of the stop bolt, the ring being guided for axial displacement and provided with rotational securing means in the longitudinal bore so that by rotating the stop bolt a variation of the initial stressing of the adaptation spring in a continuously variable manner is possible without affecting the preset spring stroke (b).
