摘要： A scroll-type apparatus having a main journal bearing which journals the drive shaft of the apparatus and is capable of pivoting by small angles with two degrees of freedom. The main journal bearing comprises three or more arcuate pads whose inner surfaces journal the drive shaft and which are pivotably supported by a stationary main bearing housing. In a preferred embodiment, each of the pads has a spherical protrusion and two rotation-preventing pins secured to its back surface. The protrusions contact the inner surface of the main bearing housing and pivotably support the pads, while the rotation-preventing pins are inserted into grooves formed on the inner surface of the main bearing housing. When a load is applied to the drive shaft causing it to tilt, the pads of the main journal bearing can tilt along with the drive shaft by pivoting about the points of contact between the spherical protrusions and the inner surface of the main bearing housing, thereby preventing edge loading of the main journal bearing.

摘要： In a scroll type compressor, the shaft of a driven scroll is rotatably supported in a sealing container so that the axis of rotation of the driven scroll shaft is deviated from the axis of rotation of a driving scroll; the wrap plates of the driving and driven scrolls are mutually combined with each other so that the parts of the side surface of the wrap plates come in contact with each other to form a compression chamber; and the driven scroll is directly driven by the driving scroll in synchronism therewith, whereby the function of compression of a fluid is obtainable during the movement of the compression chamber toward the centers of the driving and driven scrolls.

摘要： An upper housing for rotatably supporting a driving scroll in a sealing container is provided with an annular chamber to be maintained at the atmospheric pressure. The annular chamber is communicated with a compression chamber formed between the driving and driven scrolls through a discharge conduit which is formed in the driving shaft of the driving scroll. The annular chamber is communicated with the inside of the container through a throttling path. An oil stored in the lower part of the container is induced with the compression chamber during the revolution of the both scrolls to be introduced into the annular chamber. Owing to the throttling path, the oil is stored in the annular chamber to separate the inside of the container and the annular chamber kept at the atmospheric pressure.
