Title:
VANE-TYPE COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2017/094639
Kind Code:
A1
Abstract:
[Problem] To restrain a drive shaft from moving axially relative to a rotor with a simple configuration, even when liquid compression has caused the drive shaft and the rotor mounted thereon to slip in a circumferential direction relative to one another. [Solution] A movement-restraining member, which restrains a drive shaft 2 from moving axially relative to a rotor 3, is provided to an outer peripheral surface on the side opposite of the side where the drive shaft 2 protrudes out of a housing. This movement-restraining member, which is configured from a ring-shaped member 50 and fixed by pressure-fitting to the outer peripheral surface of the drive shaft 2, is preferably accommodated in an annular recessed section 3b provided in the peripheral edge of an open end of an insertion hole 3a of the rotor 3, through which the drive shaft 2 is inserted.
