DEFINITION

Classification: 123/384

Floating piston-type governor (e.g., Bessiere):

(under subclass 379) Subject matter in which the injection pump governor includes a freely floating piston whose position within the pumping cylinder is determined by (a) the amount of fluid trapped between said floating piston and a second driving piston, and (b) the position of the driving piston, and in which the effective pumping stroke may be controlled by varying the amount of trapped fluid during part or all of the pumping cycle.
