Abstract

PURPOSE:To provide a suction inlet for the center of guide block of internal gear pump and provide a discharge outlet for both ends in forward and backward rotation conditions to have unchangeable inlet and outlet even the rotation direction is changed, and to reduce numbers of parts of suction pipe system for simplifying the structure. CONSTITUTION:With a valve 16 closed, a valve 17 opened and a pump shaft 4 rotated as shown by arrow B, pinion 3 and ring gear 2 start also to rotate. Accordingly, part of left side outlet 7 of guide block 5 develops negative pressure owing to closing valve 16, negative pressure thereof sucks oil contained in inlet 6 and oil tank 8 to discharge from the right outlet 7. Further, with the valve 17 closed, the valve 16 opened and the shaft 4 rotated as shown by arrow C, the oil sucked from the inlet 6 allows to discharge from the left outlet 7. With such forward and backward rotation conditions, this enables to suck from the same inlet and discharge from either of right or left outlet 7 where an outlet may not be an inlet.
