Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, proposed a kind of motor car engine deaerator, the technical problem that the utility model solves is that extraneous steam is not easy to enter in the housing of deaerator from the valve port of bypass valve and check valve.
The purpose of this utility model can realize by following technical proposal: a kind of motor car engine deaerator, comprise housing, on described housing, be provided with suction tude and steam outlet pipe, described housing bottom is provided with return opening, in described housing, be provided with filter core, described suction tude is connected with steam outlet pipe through above-mentioned filter core, it is characterized in that, in described housing, be provided with the bypass valve that can make suction tude be connected with steam outlet pipe and the check valve that can make filter core and steam outlet pipe sealing, on described housing, have for being communicated with bypass valve inner chamber and extraneous valve port one, on described housing, also have for being communicated with check valve inner chamber and extraneous valve port two, described valve port one and valve port two places are provided with the semipermeable membrane of permeable watertight.
The working principle of this motor car engine deaerator is: when deaerator work, air-fuel mixture gas enters enclosure interior by suction tude, through the filtration of filter core, machine oil flows back to oil sump from the return opening of housing bottom, and isolated inflammable gas leads to intake manifold recycling from steam outlet pipe.Set after numerical value when the negative pressure value in housing is elevated to, check valve is closed, and stops the separation process of oil gas, prevents filter core and penetrates and cause machine oil to enter motor.After the negative pressure value in housing further raises, bypass valve is opened and is made the oil gas in suction tude directly enter into steam outlet pipe, and is sent to motor to meet the temporary transient energy needs of motor.Valve port one and valve port two can normally be worked bypass valve and check valve, and extraneous air can enter in the chamber of bypass valve and check valve by valve port one and valve port two, and steam is intercepted by semipermeable membrane, prevents that moisture from entering housing internal contamination machine oil.
In above-mentioned motor car engine deaerator, described semipermeable membrane is fixed on the outer end of valve port one and valve port two.The installation of semipermeable membrane and replacing are convenient.
In above-mentioned motor car engine deaerator, described semipermeable membrane is embedded in valve port one and valve port two.Semipermeable membrane is not easy in use to sustain damage, and has extended the working life of semipermeable membrane.
In above-mentioned motor car engine deaerator, described semipermeable membrane and valve port one and valve port two-way are crossed thermal fusion welding and are fixed.Fixing of semipermeable membrane and valve port one and valve port two is reliable, and the sealing of joint is better.
In above-mentioned motor car engine deaerator, described bypass valve is Normally closed type, and in the time that the negative pressure of enclosure interior is more than or equal to 10.5KPa, bypass valve is opened.
In above-mentioned motor car engine deaerator, described check valve is open in usual, and in the time that the negative pressure of enclosure interior is greater than 6KPa, bypass valve cuts out.
Compared with prior art, the advantage of this motor car engine deaerator is: this motor car engine deaerator arranges semipermeable membrane on valve port one and valve port two, prevent that steam from entering into the enclosure interior of deaerator, make isolated machine oil more clean, guaranteed the validity of machine oil viscosity and additive.
