    摘要: A scroll type positive displacement apparatus which can be used as a vacuum pump is disclosed. A pair of interfitting scrolls are housed in a first container which communicates with a vacuum chamber to be evacuated by the pump. The scrolls are rotated in synchrony about parallel, nonaligned axes by a drive motor. The scrolls define a plurality of spiral compression chambers which change in size when the scrolls are rotated, compressing a gas contained in the compression chambers. The shaft of one of the scrolls has a discharge port formed therein which communicates between the centermost compression chamber and the inside of a second container which adjoins the first container. The second container is partially filled with lubricating oil and communicates with the atmosphere. The discharge port is equipped with a check valve which permits compressed gas to enter the second container from the scrolls but prevents gas from flowing in the opposite direction. The pump may be further equipped with one or more oil supply passageways formed in the shaft of the scroll in which the discharge port is formed. Lubricating oil is introduced via the oil supply passageway from the second container into one or more of the compression chambers of the pump.

    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: 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: A scroll-type fluid machine, preferably, a scroll-type compressor, having a small size and improved sealing between scroll members. An orbiting scroll is interleaved with a stationary scroll. A crank mechanism is provided for causing the orbiting scroll to undergo an orbiting motion. The crank mechanism includes a crankshaft and an eccentric ring rotated in an eccentric pattern by the crankshaft. Orbital movement of the orbiting scroll is transmitted from the eccentric ring to a shaft of the orbiting scroll. The distance between the center of rotation of the crankshaft and the center of the orbiting scroll shaft is made substantially equal to the radius of orbit when the center of rotation of the crankshaft, the center of the orbiting scroll shaft, and the center of rotation of the eccentric ring are arranged along a straight line in the stated order.

    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.
