Abstract

PURPOSE: To enhance the volume efficiency by furnishing communicating parts to the internal circumference of a roller and grooves formed from a plurality of a seal parts at each end face of a roller on its bearing side, the roller being accommodated rotatably in a crank of a shaft, wherein the grooves with seal parts stretche in the circumferential direction and reduce the section area as going apart from the communication parts.
CONSTITUTION: Grooves 20-24-27 and ones 28-32-35 in the equal number are provided at the end faces 19a, 19b of a roller 19 which contact bearings 7, 8 for a shaft 3, wherein the roller 19 is held rotatably by a crank 3c of the shaft 3. of the shaft 3. These grooves 20-35 are formed from communication parts 20a-35a to the inside circumference of the roller 19 and also seal part 20b-35b, 20c-35c which extend in the circumferential direction from said communication parts 20a-35a and reduce the section area while going apart from the communication parts 20a-35a. Accordingly an oil pressure force is generated by the wedge effect due to the seal parts with rotation in both directions caused by spiral rotating of the roller 19 round its own axis, which ensures high level retention to accomplish enhancement of the volume efficienecy.
