Title:
PUMP
Document Type and Number:
Japanese Patent JPH10339279
Kind Code:
A
Abstract:
To reduce number of items while commonly using a shaft which supplies inner rotors rotational motion, even when plural internal gear pump mechanisms are arranged, and facilitate assembling after positioning the internal gear pump mechanisms.
Outer rotors 51a, 51b of two trochoid pump mechanisms are rotatably supported by means of one cylinder 15. Thus the plural outer rotors 51a, 51b are always rotatably supported at the same center. Smooth rotation is obtained even when two inner rotors 52a, 52b are driven by the same shaft 54. It is possible to easuly set the mechanisms at proper positions since side plates 30a, 30b of the two trochoid pump mechanisms and a spacer 40 are arranged with the same cylinder 15 being as a reference.
