Abstract

PURPOSE: To lubricate and seal a lap section without any pump and/or a cooler by introducing an oil from a low positioned oil reservoir into a compression room through utilization of a pressure difference between a container and the compression room, while providing an oil feeding hole piercing through a fixed scroll flat plate.
CONSTITUTION: An oil feed hole 21 is provided piercing through a fixed scroll flat plate 5a with its lower end opening in an oil reservoir 10 and its upper end opening at a position where a compression room 23 is just closed. By this mechanism, from the time on when a compression stroke just has begun, while a rotary scroll 4 is making a rotation counterclockwise within a range of 180°, the opening in the compression room is either closed with a tip of a lap portion 4b of the rotary scroll 4 or only opened into one of the closed inner compression rooms for the oil never to be poured into the outermost compression room 23. That is, only when a status entered which is shown in the figure on the right, the oil feeding hole 21 begins to communicates with the compression room 23 for the oil to pour thereinto due to a pressure difference therebetween and the lubrication and the sealing of the lap section can be conducted without any pump and/or a cooler.
