  • Patent number: 9447786
    Abstract: A compressor includes a compression mechanism and a drive shaft having an oil supply hole opened through an outer peripheral surface of the drive shaft to supply oil to a bearing surface of the drive shaft. An oil discharge passage communicating with the oil supply hole is formed by a flat surface or a recessed surface at a portion of the outer peripheral surface of the drive shaft. A trailing edge of the oil discharge passage is displaced behind a trailing edge of the oil supply hole with respect to a rotation direction of the drive shaft. A leading edge of the oil discharge passage is displaced behind a leading edge of the oil supply hole with respect to the rotation direction of the drive shaft. The oil discharge passage has a width that is no larger than a diameter of the oil supply hole.

  • Patent number: 8397921
    Abstract: A spraying means is arranged on the scum-flowing wall surface side of wall surfaces forming a scum inlet of a scum discharging mechanism. The spraying means sprays pressured water upward along the wall surface on the scum-flowing side from when a part of the scum inlet is submerged in water until the scum begins to flow into the scum inlet. As a result, even large lumps of scum exceeding 10 cm in thickness (diameter) may be lead smoothly into a pipe by the pressured water, and the amount of discharged water accompanying scum discharge may be reduced to 1/20 to 1/30 than by a conventional scum removing apparatus.
