Document Type and Number:
WIPO Patent Application WO/2023/048048
Kind Code:
A1
Abstract:
Provided is a compressing mechanism in which wear and seizure can be suppressed. The compressing mechanism is provided with a bush 60 having a first sliding surface 61 that slides along an inner surface 45a of a bush hole 45, and a second sliding surface 63 that slides along a side surface 52a of a blade of a piston. The compressing mechanism has at least one of: a first bulging portion 62 formed on one of the first sliding surface 61 and the inner surface 45a such that a gap X between the first sliding surface 61 and the inner surface 45a becomes gradually smaller in the direction in which lubricating oil Y is drawn in between the first sliding surface 61 and the inner surface 45a concomitant with rocking of the bush 60; and a second bulging portion 64 formed on the second sliding surface 63 such that a gap X between the second sliding surface 63 and the side surface 52a becomes gradually smaller in the direction in which the lubricating oil Y is drawn in between the second sliding surface 63 and the side surface 52a concomitant with advancing and retreating of the blade.
