Abstract
300,189. Landis Tool Co., (Assignees of Balsiger, H. E.). Nov. 8, 1927, [Convention date] . Fixed - abutment type; governing pumps. - The vaned rotor 15 works in a chamber formed by one cylindrical surface 11 in a fixed part 10 and another 14 in a movable block 13. The capacity of the pump is varied by moving the block 13 by means of pressure fluid from the delivery side of the pump under, the control of a manuallyoperated device 45. A piston 21 is secured to the block 13 and fluid from the delivery 20 is admitted above the piston by way of passages 25, 27. The lower piston of a valve 31 normally closes a passage 38 leading to the space above the block 13. When the part 45 is moved downwards, the passage 38 is opened and under the influence of the additional pressure above it the block 13 moves downwards until by the tilting of the floating lever 40 the passage 38 is again closed. Upward movement of the valve 31 allows the pressure fluid above the block 13 to escape by a port 36. The part 45 may be operated by a hand-wheel and screwed spindle.
