ABSTRACT:
A lateral rotary compressor comprises a compressing mechanism including a blade chamber for filling the lubricating oil, and a blade contained in the blade chamber and reciprocatingly movably between the first position where the blade chamber is increased to the maximum volume and the second position where the blade chamber is decreased to the minimum volume, and a supply tube for communicating the blade chamber with bearings and having an opening formed at the position located in a lubricating oil reservoir. The blade chamber is not communicated with the lubricating oil reservoir except via the supply tube, whereby when the blade is moved to the first position, the lubricating oil in the supply tube and the lubricating oil from the reservoir through the opening formed at the supply tube are sucked into the blade chamber, and when the blade is moved to the second position, the lubricating oil in the blade chamber and the lubricating oil from the reservoir through the opening formed at the supply tube are delivered to the bearings.
