The present invention has the advantage that:

Efficient Oil-gas Separation can be carried out to engine blow-by gas using the present invention, automotive emission is made to reach the requirement of state six Discharge standard.The present invention can efficiently separate out the lubricating oil in gas blowby and back into the oil sump of engine crankcase, subtract Few lubricating oil scatters and disappears.Structure overall flow resistance of the invention is lower；The present invention can be realized automatically and stably to be run for a long time, oil Gas good separating effect and non-maintaining has good market application prospect.

The setting of bending section extends the length of centrifugation access, increases oil mist particles in gas blowby and sends out in centrifugation access The probability of raw collision, to increase the separative efficiency of oil-gas separation mechanism, while in the centrifugation for realizing same length Oil-gas separation mechanism the space occupied size is reduced under the premise of access, enables the invention to adapt to the limited machine in inner space Motor-car.

The thickness of the tilting section of radial rib is greater than the thickness of bending section, and this makes it possible in two neighbouring middle parts Gap is generated between the bending section between disk, to collect the lubricating oil in gas blowby using horizontal segment and tilting section, is utilized Gap between bending section throws away the lubricating oil being attached on tilting section outward upwards, improves oil-gas separation efficiency.H1≥ 0.5H, during Oil-gas Separation, the path (length of radial rib tilting section) for collecting lubricating oil is longer, the collection of lubricating oil Efficiency is preferable.Angle between tilting section and bending section is α, and the too small then oil gas separation of α is promoted unobvious；α is excessive, moistens Part cannot be thrown away lubricating oil from being easy to be blocked generation rebound at the bending section of disk in the upper layer, can reduce oil gas point instead From efficiency.5 °≤α≤45 °, oil gas separation can either be promoted, and lubricating oil is avoided to spring back.α is preferably 10 °.

Way to cycle oil includes step and lower bearing, can self-lubricate lower bearing, for the long-term non-maintaining fortune of the present invention Row provides safeguard.

The present invention drives oil using the higher lubricating oil of the pressure in motor vehicle as power, by impeller-driven central axis Gas separating mechanism rotary work, without other setting power device and control device, structure is simple, provides guarantor for non-maintaining operation Barrier.

The vertical cross-section and jet of nozzle opening are oval, can increase the lubricating oil of ejection and connecing for primary blades Contacting surface product (area of stress surface), oil spout is more preferable to the acting effect of primary blades, improves the kinetic energy of oil spout to the rotation of central axis The transformation efficiency of energy.Impeller and primary blades contact lubricating oil for a long time in rotary work, if without locking measures, impeller It is easy to occur to loosen even obscission on center shaft in long-term use.

Primary blades because pressure direction suffered by spray bar oil spout be impeller on center shaft screw direction, can be in length The operational process of phase is automatic and constantly realizes the technical effect of impeller anti-loose, provides basis for non-maintaining operation of the invention.

If impeller and central axis use the conventional connection type of optical axis transition fit, because being merely by frictional force Torque is transmitted, when torque is greater than frictional force, just will appear does not have relative rotation or asynchronous rotation between impeller and axis Phenomenon, such impeller and axis are easy for wearing.In the present invention, impeller is connect with central axle threads, avoids impeller and axis The phenomenon that asynchronous rotation.

Opening on step side wall is located in the negative pressuren zone, can be by the oil in step and lower bearing outward Suction casing inner cavity keeps way to cycle oil more unobstructed, avoids occurring choking phenomenon at step and lower bearing, prevents simultaneously The lubricating oil that only jet sprays enters lower bearing, is the important leverage that the present invention is capable of long-term non-maintaining operation.

The inner ring of the upward bearing of upper spring transmits torque, to avoid opposite between upper bearing (metal) inner ring and central axis upper end It slides and wears central axis upper end and bearing inner race, and then extend upper bearing (metal) knot related to central axis matching part The service life of structure ensures the long-term non-maintaining stable operation of the present invention.

When work, under the differential pressure action that center axis rotation generates, the lubricant mist of housing cavity bottom is by oil-through-hole quilt The inner hole of central axis is sucked, then mist of oil is downwardly into the axial passageway passed through for oil gas through return flow line.

The setting of inner hole and return flow line has the function of three aspects: 1. mist of oil passes through return flow line, flows through upper bearing (metal) When lubricating action is generated to upper bearing (metal), ensure that upper bearing (metal) being capable of long-term non-maintaining normal operation.After 2. mist of oil passes through return flow line Into the axial passageway passed through for oil gas, when by each middle part separation disk, the glue on middle part separation disk can be cleaned Matter and impurity avoid the gap blocking between adjacent middle part separation disk, ensure long-term non-maintaining operation.3. passing through each middle part When separating disk, the oil film of flowing is formed after being thrown in inner walls under the influence of centrifugal force, prevents from isolating in gas blowby Colloid and impurity bonding on the inner wall of the housing, ensure that the present invention being capable of long-term non-maintaining operation.

The arc groove of lower end opening is formed between the adjacent primary blade of impeller, the lubricating oil convenient for being injected in primary blades exists Smooth outflow impeller under the action of gravity, and then can be flowed out by oil return opening.

In short, the present invention can automatically begin to work after motor vehicle igniting, it is automatically stopped work after motor vehicle is flame-out, Whole work process need not be automatically controlled, without additional power device, can carry out efficient Oil-gas Separation to engine blow-by gas, subtract Scattering and disappearing for few lubricating oil, can be realized operation steady in a long-term without maintenance, have very high market value.
