  • Speed adjust
    Patent number: 4214437
    Abstract: A governor is adjusted as to speed by having a fluid diaphragm directly connected to a speeder spring which acts against a thrust bearing which bears against the flyweight toes. The fluid diaphragm is resisted by a set of low speed springs at all times. A lost motion arrangement brings a set of normal speed springs into use at larger diaphragm movement so that the response to the speed adjustment varies for different values of pressure acting upon the diaphragm.
