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.
Claims2
In a governor for an engine having
- a. a housing,
- b. fuel feed means in the housing for regulating the fuel fed to the engine,
- c. a ballhead in the housing with
- (i) flyweights pivoted thereto,
- (ii) means for rotating the ballhead at a speed directly related to the engine speed,
- (iii) a thrust bearing contacting the flyweights, and
- (iv) a speeder rod attached to said thrust bearing,
- (v) said speeder rod forming a part of the fuel feed means,
- d. a speeder spring biasing the thrust bearing against the flyweights, and
- e. a speeder plug bearing against the speeder spring;
- the improved structure for positioning the speeder plug comprising:
- f. a diaphragm attached to the housing,
- g. a diaphragm plate attached to the diaphragm, and
- h. a diaphragm case forming a fluid chamber on one side of the diaphragm plate,
- j. an actuator rod securely attached to the diaphragm plate, on the side of the plate opposite the chamber,
- k. the speeder plug securely attached to the actuator rod,
- m. so that the speeder plug is directly connected to the diaphragm plate,
- n. low speed compression springs bearing against the same side of the diaphragm plate as the actuator rod is attached to,
- o. a stud attached to the diaphragm plate and extending through the diaphragm case,
- p. a nut on the stud above the diaphragm case,
- q. at least one normal speed spring attached to the top of the diaphragm case,
- r. a crosshead assembly on top of the spring,
- s. space between the top of the crosshead assembly and the nut when the diaphragm is in the position nearest the diaphragm case whereby only the low speed compression spring biases the diaphragm plate until the diaphragm plate moves downward and the nut contacts the crosshead assembly.

In a system having
- a. an engine supplying power to
- b. a load,
- c. a sensor and transmitter operatively associated with the load for producing a fluid pressure related to the load speed requirements,
- d. a governor for the engine, said governor including
- e. a housing,
- f. fuel feed means in the housing for regulating the fuel fed to the engine,
- g. a ballhead in the housing with
- (i) flyweights pivoted thereto,
- (ii) means for rotating the ballhead at a speed directly related to the engine speed,
- (iii) a thrust bearing contacting the flyweights, and
- (iv) a speeder rod attached to said thrust bearing,
- (v) said speeder rod forming a part of the fuel feed means,
- h. a speeder spring biasing the thrust bearing against the flyweights, and
- j. a speeder plug bearing against the speeder spring;
- the improved structure for positioning the speeder plug comprising:
- k. a diaphragm attached to the housing,
- m. a diaphragm plate attached to the diaphragm,
- n. an actuator rod securely attached to the diaphragm plate,
- o. the speeder plug connected to the actuator rod so that movement of the actuator rod changes the position of the speeder plug,
- p. said diaphragm plate having a first range of positions so that the actuator rod is in a low speed position,
- q. said diaphragm plate having a second range of positions so that the actuator rod is in a normal speed position,
- r. low speed compression springs bearing against the diaphragm plate at all times, and
- s. normal speed springs biasing the diaphragm plate when the diaphragm plate moves to the normal speed position.
