The utility model is characterized in that a gas cylinder cover and a breathing apparatus baffle compose a breathing chamber, the filter screen is arranged at the ventilated port of the breathing chamber which is communicated with a breathing apparatus pipe of the gas cylinder cover, a pressure limiting valve is arranged on the gas cylinder cover. A ball valve is arranged in the gas cylinder cover. The utility model is simple in structure, compact, and reasonable; high in oil separating efficiency and can achieve a good oil and gas separating effect, which can make the partial engine oil in the oil smoke and the gas return to a crankcase, thus to prevent the piston, the valve and the oil spraying apparatus from damage due to the burning of the engine oil, meanwhile to reduce the consumption of the engine oil, improve the engine economical efficiency and prevent the environment and the personality from hurt due to the oil smoke and the gas in the engine crankcase.
Description
Technical field
The utility model relates to a kind of air-breather of motor, specifically oil smoke, the gas of engine interior is sent into the suction tude recycling behind strainer filtering.
Background technique
At present, engine ventilating device normally utilizes the ventilation plant of steel wire as crankcase of adding some points suitable in the filler cap that is contained in the crankcase side.During engine operation, lubricant mist that produces in the crankcase and the small part high-pressure gas in the cylinder bleed by the gap between piston ring and the cylinder wall in the crankcase, along with crankcase pressure raises, gas in the part crankcase enters atmosphere through filter screen and filler cap, the lighter is a mist of oil like this, and weight person is with oil dripping.Cause environmental pollution and worsen motor work-yard on every side.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provide a kind of air-breather of motor, oil smoke, the gas of engine interior can be sent into the suction tude recycling behind strainer filtering, fluid flows back to crankcase, helps improving the Economy of motor and reduces the pollution of motor to surrounding environment.
Main solution of the present utility model is achieved in that
The utility model mainly comprises the valve mechanism cover of cylinder head top, and feature is the respiratory chamber that valve mechanism cover and resuscitation apparatus dividing plate constitute, and at this respiratory chamber ventilating hole filter screen is set, and respiratory chamber is breathed organ pipe with valve mechanism cover and is communicated with, and pressure-limit valve is set above valve mechanism cover.
Described resuscitation apparatus dividing plate is provided with spill port.
The described ball valve that in valve mechanism cover, is provided with.
Described pressure-limit valve is made of capping, spring, spring end cap and diaphragm unit, sets gradually spring, spring end cap and diaphragm unit in capping.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; The oil-dividing efficiency height, can reach good oil gas separation, can make the part machine oil in oil smoke, the gas get back to crankcase, avoid the harm of burn oil to piston, valve and oil sprayer, simultaneously can reduce oil consumption, improve the Economy of motor, exempt the injury of engine crankcase oil smoke, gas environment and personnel.

Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of valve mechanism cover 1, resuscitation apparatus dividing plate 2, filter screen 3, pressure-limit valve 4, (capping 4a, spring 4b, spring end cap 4c, diaphragm unit 4d), breathing organ pipe 5, ball valve 6 and the suction tude 7 etc. of cylinder head top.
As shown in Figure 1 and Figure 2, the respiratory chamber 2a of valve mechanism cover 1 and resuscitation apparatus dividing plate 2 formations.Described resuscitation apparatus dividing plate 2 is provided with spill port 2b.At this respiratory chamber 2a ventilating hole filter screen 3 is set, respiratory chamber 2a breathes organ pipe 5 with valve mechanism cover and is communicated with, and pressure-limit valve 4 is set above valve mechanism cover 1.Ball valve 6 is set in valve mechanism cover 1.
Described pressure-limit valve 4 is made of capping 4a, spring 4b, spring end cap 4c and diaphragm unit 4d, sets gradually spring 4b, spring end cap 4c and diaphragm unit 4d in capping 4a.
Working principle of the present utility model and working procedure:
Oil smoke, gas enter respiratory chamber 2a by filter screen 3, and this respiratory chamber 2a can become gas and fluid to the gas separation that contains mist of oil, and filter screen 3 can well be removed the elaioleucite in the ventilation.
After the gas cooling, the part mist of oil condenses into liquid and flows back to crankcase by the little spill port 2b on the resuscitation apparatus dividing plate 2.Along with the increase of load and the increase of lubricating oil temperature, the amount and the pressure of oil smoke, gas increase thereupon in the crankcase, when pressure rises to certain value, will push ball valve 6 open, more soot gas enters respiratory chamber 2a, and the elaioleucite in the gas flows back to crankcase after separating.When gas pressure is elevated to certain value among the respiratory chamber 2a, overcome the pressure of the spring 4b above the diaphragm unit 4d, push diaphragm unit 4d open and drive seal washer, the part soot gas enters breathes organ pipe 5, is inhaled into gas mixed combustion in cylinder and the cylinder through suction tude 7.
Above air-breather is mainly finished by pressure-limit valve 4.Suppress spring end cap 4c and diaphragm unit 4d by capping 4a downwards through spring 4b, diaphragm unit disconnects the connection between respiratory chamber 2a and the breathing organ pipe 5.When the pressure of respiratory chamber 2a reached certain value, diaphragm unit 4d was moved up by the pushing of the gas in the 2a of respiratory chamber chamber, and pressure-limit valve 4 is opened, and respiratory chamber 2a on the valve mechanism cover and breathing organ pipe 5 are communicated with.As shown in Figure 3, the pressure-limit valve 4 in the engine ventilating device, the valve as in respiratory chamber 2a and breathing organ pipe 5 paths can guarantee the pressure stability in the valve mechanism cover.
This device owing to be directly the gas in the crankcase to be introduced in the cylinder to burn, so avoid the mist of oil in the engine crankcase to be discharged to the external world, causes the harm of motor to surrounding environment.
