A HYDRAULIC PUMP ASSEMBLY

A hydraulic pump assembly comprises a rotatable piston drum (20) with at least one centrifugal lever (23) pivotally attached thereto for radial movements between radial flanges (20′) under the action of centrifugal force at rotation of the piston drum. The centrifugal lever (23) is arranged to contr...

More Information
Summary:A hydraulic pump assembly comprises a rotatable piston drum (20) with at least one centrifugal lever (23) pivotally attached thereto for radial movements between radial flanges (20′) under the action of centrifugal force at rotation of the piston drum. The centrifugal lever (23) is arranged to control the position of a valve member, preferably a ball (22), at the opening end of a bore (21) in the piston drum (20). There is a defined friction surface (28; 32) between the lever (23) and one of the radial flanges (20′), and there are spring means (29-31; 25, 33) for resiliently biasing the lever against said one of the flanges.
