Title:
DISCHARGE MECHANISM OF POSITIVE-DISPLACEMENT COMPRESSOR
Document Type and Number:
Japanese Patent JP2014206173
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a positive-displacement compressor capable of ensuring high efficiency and high reliability by greatly reducing the internal leakage of working gas that causes the degradation in efficiency relating to a compression mechanism part, excessive compression phenomenon, re-compression loss, insufficient compression and the like.SOLUTION: A discharge mechanism of a positive-displacement compressor is configured so that a valve mechanism member that is a combination of a flat gate valve 12 slidably contacting a wall surface of a movable mechanism member, formed of a linear seal part, and including a tip end portion and a sidewall seal surface, a support portion supporting the flat gate valve 12, a partition plate 13 having a sidewall seal surface provided on an opposite side to a side on which a gas passage is provided between the flat gate valve 12 and the support, and an elastic body 15 supporting these components is attached to a valve storage chamber having one end open to a compression chamber 10 provided in a fixed mechanism member.
