Preferably, be provided with labyrinth structure in the said Oil-gas Separation chamber.
Preferably, be provided with cyclone structure in the said Oil-gas Separation chamber.
Preferably; Outlet port, said exhaust passage is equipped with pressure equaliser; This pressure equaliser comprises the housing that outlet pipe is installed, and is provided with first chamber that is communicated with the exhaust passage in said Oil-gas Separation chamber and second chamber that is communicated with outlet pipe in the housing, and said second chamber is equipped with a spring; The spring upper end compresses a peripheral shape and the consistent diaphragm of housing internal chamber wall shape, and the upper open end of said housing is installed with the resuscitation apparatus lid.
Preferably, said outlet pipe is connected in the middle of engine air filter and the pressurized machine.
Compared with prior art, the present invention is provided with the oil gas structure integratedly on engine air cylinder cap, controlled the respirator apparatus volume effectively, has made things convenient for motor to use whole supporting when installing.

Embodiment
Below in conjunction with accompanying drawing, specific embodiments of the invention is described in detail, but is to be understood that protection scope of the present invention does not receive the restriction of embodiment.
Shown in Fig. 1-4; This motor respirator apparatus comprises the Oil-gas Separation chamber that is arranged at integratedly on the engine air cylinder cap 1; Said Oil-gas Separation chamber opening end is equipped with resuscitation apparatus cover plate 3; This resuscitation apparatus cover plate 3 and Oil-gas Separation chamber constitute the Oil-gas Separation chamber of a sealing; Be provided with in the said Oil-gas Separation chamber and let oil gas inlet 13 that in-engine oil gas gets into separate the oil that obtains and flow back to the interior return opening 16 of cylinder head 11 with letting, said resuscitation apparatus cover plate 3 is provided with the exhaust passage that is used to discharge the gas that obtains after the separation.This motor respirator apparatus makes gas and oil separating plant simple in structure through the Oil-gas Separation chamber is set on motor housing 1 integratedly, and reliability is high.
As shown in Figure 5, be provided with labyrinth structure 14 and cyclone structure 15 in the said Oil-gas Separation chamber.Such structure makes the oil gas that gets into from oil gas inlet 13 obtain secondary separation.Wherein, labyrinth structure 14 makes oil gas separated first because of condensation, and cyclone structure 15 makes the oil gas that lives through separation first obtain once more under the action of the centrifugal separating, and then makes oil gas obtain isolation of purified completely.
As shown in Figure 6, said respirator apparatus is equipped with the pressure equaliser that is communicated with the exhaust passage.This pressure equaliser comprises the housing that outlet pipe 12 is installed; Be provided with first chamber 18 that is communicated with the exhaust passage in said Oil-gas Separation chamber and second chamber 17 that is communicated with outlet pipe 12 in the housing; Said second chamber 17 is equipped with a spring 4; Spring 4 upper ends compress a diaphragm 5 that peripheral shape is consistent with the housing cavity shape, and the upper open end of said housing is installed with resuscitation apparatus lid 6.Said outlet pipe 12 is connected in the middle of engine air filter and the pressurized machine.In the motor process, said diaphragm 5 second chamber 17 receive upwards through separating the pressure of back gas, diaphragm 5 reaches the spring thrust that makes progress at the suction-combining force that first chamber 18 also receives downward outlet pipe air pressure simultaneously.The strength that makes progress that receives when diaphragm 5 is during greater than downward strength, and diaphragm moves to the 3rd chamber 19 up, and win chamber 18 and second chamber 17 are communicated, and the oil gas after the separation is discharged from outlet pipe; The strength that makes progress that receives when diaphragm 5 is during less than downward strength, and diaphragm 5 moves down, isolates each other until withstood, make win chamber and second chamber by the chamber wall, prevents to destroy the pressure balance in the crankcase.The shape of wherein said first chamber and second chamber, structure and size are set according to the concrete condition of motor, so that receive suitable gas pressure and the suction-combining force on the diaphragm 5 during engine operation.
The present invention is arranged at respirator apparatus on the valve mechanism cover integratedly, has effectively controlled the volume of respirator apparatus, and simple with peripheral part assembling, and performance is good, and reliability is high.This device especially is fit to and the supporting use of passenger car.
More than disclosedly be merely a specific embodiment of the present invention, still, the present invention is not limited thereto, any those skilled in the art can think variation all should fall into protection scope of the present invention.
