Centrifugal governor for regulating the rpm of internal combustion engines

Claim 2

In a centrifugal-type rpm regulator connected to the fuel quantity control member of a fuel injection pump associated with an internal combustion engine, the improvement comprising, A. a governor member, B. means for displacing said governor member as a function of the engine rpm, C. a first lever means connecting said governor member with said fuel quantity control member, said first lever means having a path of travel through which it is displaced by said governor member, D. a regulator spring connected to said first lever means for opposing the force exerted on said governor member by the means defined in (B), E. an additional idling spring means for opposing during the starting and idling rpm''s the force exerted on said governor member by the means defined in (B), said additional idling spring means having one end thereof located within a housing within which said governor member is mounted, F. an arbitrarily settable operator lever connected to said regulator spring for varying the bias thereof and G. a second lever means connecting said arbitrarily settable operator lever to said additional idling spring means for varying the moment of activation thereof with respect to the position of said governor member as a function of the position of said operator lever, said additional idling spring means being movable by said second lever means into and out of said path of travel, said operator lever in its positions beyond the idling setting arranged to de-activate at least partially said additional idling spring means.

Claim 3

An improvement as defined in claim 1, wherein said additional idling spring means, when positioned in said path of travel arrives in abutment with said first lever means after a predetermined travel thereof dependent upon the position of said additional idling spring means; said additional idling spring means, when positioned beyond said path of travel, remains ineffectIve for the entire displacement of said first lever means.

Claim 4

In a centrifugal-type rpm regulator connected to the fuel quantity control member of a fuel injection pump associated with an internal combustion engine, the improvement comprising, A. a governor member, B. means for displacing said governor member as a function of the engine rpm, C. a first lever means connecting said governor member with said fuel quantity control member, D. a regulator spring connected to said first lever means for opposing the force exerted on said governor member by the means defined in (B), E. an additional idling spring means for opposing during the starting and idling rpm''s the force exerted on said governor member by the means defined in (B), F. an arbitrarily settable operator lever connected to said regulator spring for varying the bias thereof and G. a second lever means connecting said arbitrarily settable operator lever to said additional idling spring means for varying the moment of activation thereof with respect to the position of said governor member as a function of the position of said operator lever, said second lever means including: a. a swinger lever the position of which is determined by said arbitrarily settable operator lever, b. a pivotally held lever having an end in engagement with said additional idling spring means for shifting the same and c. a drag spring having one end connected to said swinger lever and another end connected to said pivotally held lever; said arbitrarily settable operator lever determines the position of said additional idling spring means through said swinger lever, said drag spring and said pivotally held lever.

Claim 5

In a centrifugal-type rpm regulator connected to the fuel quantity control member of a fuel injection pump associated with an internal combustion engine, the improvement comprising, A. a governor member, B. means for displacing said governor member as a function of the engine rpm, C. a first lever means connecting said governor member with said fuel quantity control member, D. a regulator spring connected to said first lever means for opposing the force exerted on said governor member by the means defined in (B), E. an additional idling spring means for opposing during the starting and idling rpm''s the force exerted on said governor member by the means defined in (B), F. an arbitrarily settable operator lever connected to said regulator spring for varying the bias thereof and G. a second lever means connecting said arbitrarily settable operator lever to said additional idling spring means for varying the moment of activation thereof with respect to the position of said governor member as a function of the position of said operator lever, said second lever means including: a. a swinger lever the position of which is determined by said arbitrarily settable operator lever, b. a pivotally held lever having an end in engagement with said additional idling spring means for shifting the same and c. a drag spring having one end connected to said swinger lever and another end connected to said pivotally held lever; said arbitrarily settable operator lever determines the position of said additional idling spring means through said swinger lever, said drag spring and said pivotally held lever.
