Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
As shown in Figure 1, a kind of oil-gas separating device of engine, it comprises the housing 1 of cavity body structure.Housing 1 is provided with mazy type separation chamber 11 and spring-piece type separation chamber 12.Mazy type separation chamber 11 and spring-piece type separation chamber 12 as a whole.Fig. 1 is the sectional view of the present embodiment, and the entrance of mazy type separation chamber 11 is connected with suction port 2, and the outlet of mazy type separation chamber 11 is communicated with the entrance of spring-piece type separation chamber 12.Spring-piece type separation chamber 12 is connected with the longitudinal wall 122 that three arrange ventilating hole 124.Ventilating hole 124 is located at longitudinal wall 122 top.Ventilating hole 124 is connected with elastic block piece 121.Elastic block piece 121 is fitted for spring sheet and longitudinal wall 122 and is blocked ventilating hole 124.When elastic block piece 121 is subject to enough power, elastic block piece 121 separates with ventilating hole 124; When external force disappearance elastic block piece 121 recovers again to block ventilating hole 124.Overhead gage 123 is provided with above ventilating hole 124.Overhead gage 123 is a level board, and in order to air-flow resilience is effective, overhead gage 123 is more close with ventilating hole 124 upper end.If the inwall of housing upper end and ventilating hole 124 are relatively, overhead gage 123 can not be established.Longitudinal wall 122 lower end is provided with back oil road 125.Longitudinal wall 122 lower end is arch, back oil road 125 through longitudinal wall 122 left and right plane.Longitudinal wall 122 has three.On the left of spring-piece type separation chamber 12, mazy type separation chamber 11 and spring-piece type separation chamber 12 separate by first piece of longitudinal wall 122.Mazy type separation chamber 11 is provided with five pieces of oil baffles 111 fixing with housing 1, and oil baffle 111 has one end to be unsettled.Oil baffle 111 is sheet.Oil baffle 111 left end on the left side and front end, rear end and housing 1 are fixed, and right-hand member is unsettled.Oil baffle 111 right-hand member and the longitudinal wall 122 on the right are fixed, and front end, rear end and housing 1 are fixed, and left end is unsettled.The free end of oil baffle 111 intersects mutually.Form runner between upper and lower two pieces of oil baffles 111, free end overlap overlooked by upper and lower two pieces of oil baffles 111.Lower end, mazy type separation chamber 11 is entrance, and suction port 2 is located at housing 1 lower end.Suction port 2 upper end is communicated with mazy type separation chamber 11 entrance, and suction port 2 lower end connects suction tude (not shown).Upper end, mazy type separation chamber 11 is outlet, is the ventilating hole 124 on first piece of longitudinal wall 122 on the left of spring-piece type separation chamber 12.On the right side of spring-piece type separation chamber 12, first piece of longitudinal wall 122 and housing 1 form spring-piece type separation chamber 12 and export.The outlet of spring-piece type separation chamber 12 is connected to return opening 3 and air outlet 4.Air outlet 4 is located at housing 1 upper end, and lower end, air outlet 4 exports top with spring-piece type separation chamber 12 and is communicated with, and upper end, air outlet 4 is connected (not shown) with Pcv valve.Return opening 3 is located at housing 1 lower end, and return opening 3 upper end and spring-piece type separation chamber 12 export bottom and be communicated with, and return opening 3 lower end is connected (not shown) with return tube.Housing 1 bottom interior wall is slope 13, and slope 13 is high-end to be connected with suction port 2, and slope 13 low side is connected with return opening 3.Slope 13 becomes certain tilt angle with horizontal plane, makes the lower end of mazy type separation chamber 11 higher than the lower end of spring-piece type separation chamber 12.
The air-flow of air-fuel mixture enters mazy type separation chamber 11 by suction port 2, and clashed into by oil baffle 111 and isolate comparatively larger oil droplet, oil droplet falls surface, slope 13, flows into return opening 3 by back oil road 125 along slope 13.With the air-fuel mixture air-flow impact elasticity catch 121 dripped compared with light oil, ventilating hole 124 opens an interspace, because this gap is narrow and small, air-flow by time flow velocity increase, and the direction of air-flow is subject to elastic block piece 121 controls, air-flow impacts overhead gage 123 by gap rapidly.A part of machine oil is separated by elastic block piece 121 when impact elasticity catch 121 in the process, and a part is separated by overhead gage 123 when air-flow impacts overhead gage 123 rapidly.Because oil gas particle is comparatively large, because inertia is large in impact process, in the process that airflow direction changes rapidly, be easily separated, thus reach the effect of Oil-gas Separation.The oil droplet be separated falls surface, slope 13, flows into return opening 3 by back oil road 125 along slope 13.
