Abstract

PURPOSE: To obtain the low-priced simple constitution of a pump apparatus for lubricating oil etc, by drilling a concavity, holes, and holes, and passages etc inside a rotary shaft and accomodating balls, ball seats etc. in the said holes etc. while, forming the eccentric cylinder part on the outside of the shaft.
CONSTITUTION: A ball 37 is accomodated in the circular concavity 36 on an input shaft 7 so that the ball can make airtight contact with the inner peripheral side wall of the concavity. The seat 41 having a small hole 40 drilled in the center is inserted into a hole 38, and a small ball 42 is accomodated in the hole 38 so as to sit freely inside the small hole 40. An eccentric ring 58 is insetted onto the outer periphery of the input shaft part 7a, at the position of the concavity 36 and the hole 38. When the input shaft 7 rotates, the ball 37 is shifted in the concavity by the eccentric ring 58, accordingly the lubricating oil is sucked from the small ball 42, and discharged from the ball 48.
