Abstract
The utility model relates to a pressure boost petrol engine part field, concretely relates to rubber crankcase ventilation pipe, including crankcase ventilation pipe body, diameter assorted coil spring is managed with the crankcase ventilation to this internal being equipped with of crankcase ventilation pipe. Coil spring makes for stainless steel material. The utility model has the advantages of it is flat to prevent that rubber crankcase ventilation pipe from being inhaled, avoids ventilation system to block up to simple structure.
Description
Technical field
The utility model relates to gasoline supercharging engine part field, is specifically related to a kind of rubber crankcase bleed pipe.
Background technique
In today that compact car is more and more popularized, the consumption level of motor car engine also becomes the factor considered emphatically when Consumer purchases car more and more.Therefore small displacement supercharging gasoline engine arises at the historic moment, with diesel engine unlike, the pressurized machine of petrol engine does not work when low speed and load, therefore causes and have different pressure under the different operating modes of gas handling system.As the crankcase ventilation guard system directly connecting suction tude, pressure boundary is also change.During non pressurized pattern, the negative pressure that descent of piston brings directly is communicated in crankcase bleed pipe, and the rubber crankcase bleed pipe of conventional gasoline machine at this moment will be flat by suction, and cause ventilation system to block, crankcase pressure is abnormal.
Model utility content
The purpose of this utility model is to solve the problem, and provides a kind of rubber crankcase bleed pipe.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of rubber crankcase bleed pipe, comprises crankcase ventilation tube body, is provided with the helical spring matched with crankcase bleed pipe diameter in described crankcase ventilation tube body.
Helical spring is that stainless steel material is made
The beneficial effects of the utility model are: prevent rubber crankcase bleed pipe from being inhaled flat, avoid ventilation system to block, and structure are simple.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Embodiment: see Fig. 1.
A kind of rubber crankcase bleed pipe, comprises crankcase ventilation tube body 1, is provided with the helical spring 2 matched with crankcase bleed pipe diameter in described crankcase ventilation tube body 1.
Helical spring 2 is made for stainless steel material.
The design illustrates: rubber crankcase bleed pipe is between deaerator and intake manifold, and when boost mode, airflow direction flows to deaerator by pressurized machine, is malleation.When non pressurized pattern, the air-intake negative-pressure that descent of piston produces is delivered to crankcase bleed pipe by intake manifold, and now spring is played a supporting role, and avoids being inhaled flat.
What embodiment of the present utility model announced is preferred embodiment; but be not limited thereto; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and change, but only otherwise depart from spirit of the present utility model, all in protection domain of the present utility model.
Claims (2)
1. a rubber crankcase bleed pipe, is characterized in that: comprise crankcase ventilation tube body, is provided with the helical spring matched with crankcase bleed pipe diameter in described crankcase ventilation tube body.
2. a kind of rubber crankcase bleed pipe according to claim 1, is characterized in that: helical spring is that stainless steel material is made.
