摘要： Minimization is allowed while improving the separation efficiency in an oil separator that separates from gas oil in a mist form included in a blow-by gas. The oil separator according to the present invention includes a plurality of separation discs that are provided rotatable together with a spindle and layered in an axis direction of the spindle, a nozzle that is provided to protrude from a lower circumferential face of the spindle and configured to rotate the spindle by injection of an oil, a lower case that is provided with a gas inflow part into which blow-by gas flows and an oil discharge part into which an oil after separation is discharged, an upper case that sections together with the lower case a housing chamber in which the spindle, the separation discs and the nozzle are housed, and a sectioning member that sections the housing chamber into a primary separation chamber configured to primarily separate the oil mist and into a secondary separation chamber that secondarily separates the oil mist included in the gas being the target of treatment after primary separation, and forms between the nozzle and the separation discs a communication opening that guides the gas being the target of treatment.

摘要： An object of the present invention is to increase, in an oil separator, the removal efficiency of the oil contained in target gas. The oil separator 2 according to the present invention includes: a plurality of separation disks that are rotatable together with a spindle and that are laminated in an axial direction of the spindle; a nozzle that is projected from a part of a peripheral surface of the spindle, the part being located below with respect to the separation disks, and that injects oil from an injection hole to rotate the spindle around an axis; and a housing 11 that includes a cylindrical side wall and defines a chamber accommodating the spindle, the separation disks, and the nozzle. The oil separator 2 is characterized in that a plurality of longitudinal ribs 24 extending in the vertical direction are circumferentially formed on the inner surface of a body cover 22 (the side wall).

摘要： The purpose of the present invention is to enhance the efficiency in removing oil contained in target gas in an oil separator that separates oil mist contained in target gas from the gas. The oil separator 2 according to the present invention includes a cylindrical housing 11 that accommodates a rotor and that is provided with a gas discharge portion 24 (first exhaust portion), the oil separator being configured to introduce target gas from a rotation center side of the rotor to condense oil mist and emit condensed oil from an outer peripheral edge of the rotor and further being configured to discharge from the housing 11 through the gas discharge portion 24 the blow-by gas (target gas) after having the oil mist separated. The oil separator 2 is characterized to include a dome portion 61 (sectioning member) that covers from an outside of the housing 11 the gas discharge portion 24 and sections a closed space around the gas discharge portion 24 and an outlet pipe 62 (second exhaust portion) that is provided to the dome portion 61 and that discharges the blow-by gas from the closed space that is sectioned by the dome portion 61.

摘要： The purpose of the present invention is to increase separation efficiency when separating oil mist contained in target gas from the gas. In order to achieve the purpose, the present invention uses a rotor 31 that separates oil mist from target gas (blow-by gas). This rotor 31 includes a separation disk group having separation disks 34 made with a plurality of truncated cone shape plate members layered. The separation disk group includes a first space (hollow part formed with attachment opening 34a) and a second space (gaps between separation disks 34), the first space being formed on a rotation center side of the rotor 31 and the second space being formed between the separation disks that are laid over and being in communication with the first space. The first space has disposed an oil introducing portion (gap between the upper end of the spindle 32 and the upper side sealing member 42) that introduces oil. Oil is introduced from the oil introducing portion and target gas is introduced into the first space, target gas and oil introduced from the oil introducing portion are made to flow from the first space to the second space to be discharged outward from an outer peripheral edge of the separation disk group, while rotating the rotor 31.

摘要： An oil separator configured to separate from gas mist oil contained in target gas of the present invention is aimed to enhance separation efficiency of oil mist contained in target gas while reducing the weight of the separation disks. The oil separator of the present invention includes a rotor. This rotor has a plurality of separation disks 34 (61, 62) layered along the axis line of the spindle. Each of the separation disks 34 are configured with truncated cone shape plate members and have formed concavo-convex ribs 64, 65 extending from the rotational center in the radiation direction on the outer peripheral side parts 61b, 62b corresponding to the inclined surfaces of the truncated cone. The concavo-convex ribs 64, 65 include first convex portions 66 and second convex portions 67 where the first convex portions 66 include on the outer peripheral side parts 61b, 62b a convex on the front surface side and a concave on the back surface side, and the second convex portions 67 include on the outer peripheral side parts 61b, 62b a convex on the back surface side and a concave on the front surface side.
