Description
Technical field
This utility model relates to static organ, a kind of static organ for chain saw fuel tank.
Background technology
At present, during gasoline chain saw work, lubricating oil pump needs that the lubricating oil in sump is constantly supplied to guide plate and chain cools down and lubricates, and when diminishing along with the minimizing pressure of machine oil in sump after work a period of time, machine oil supply discontinuity easily occurs.For above-mentioned situation, when being embodied as, we can install static organ on fuel tank, and outside atmosphere enters fuel tank by static organ, increases the pressure in fuel tank, thus avoids failure of oil feed.But the existing static organ for sump is the check valve that rubber is made, such static organ and machine oil Long contact time are the most aging, are easily subject to the impact of temperature and aging simultaneously, finally lose its effect.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of static organ for chain saw fuel tank, and this balancer mechanism is difficult to aging, and service life is long, stable performance.
For solving above-mentioned technical problem, the technical scheme that this utility model provides is: a kind of static organ for chain saw fuel tank, and it includes that metal cartridge, one end of described metal cartridge stretch in chain saw fuel tank, and the other end is in outside chain saw fuel tank；Described metal cartridge is provided with axial ventilation through hole；In described ventilation through hole, that one end outside chain saw fuel tank is provided with the steel ball of activity；It is additionally provided with, in described ventilation through hole, the stage clip offseted with steel ball；Wherein, metal cartridge stretches into that one end in chain saw fuel tank and is fixed with the gland offseted with stage clip, and described gland is provided with the pore through with through hole of ventilating.
Preferred as one, described pore and ventilation through hole coaxial line.
Preferred as one, described metal cartridge is provided with the annular groove coordinated with chain saw fuel tank.
Preferred as one, described ventilation through hole includes the taper connection hole of air access holes, air travels through aperture and connection air access holes and air travels through aperture；The aperture of described air travels through aperture is more than the aperture of air access holes, and the aperture of air travels through aperture is more than the diameter of steel ball, and the aperture of air travels through aperture is more than the diameter of stage clip；The diameter of described air access holes is less than the diameter of steel ball, and the diameter of air access holes is less than the diameter of stage clip；Described taper connection hole is consistent with the diameter of air access holes with the diameter of that end that air access holes connects, and described taper connection hole is consistent with the diameter of air travels through aperture with the diameter of that end that air travels through aperture connects；Described stage clip offsets with the side of steel ball, and the opposite side of described steel ball offsets with the hole wall in taper connection hole.
After using above structure, this utility model compared with prior art, has the advantage that it includes metal cartridge, and one end of metal cartridge is stretched in chain saw fuel tank, and the other end is in outside chain saw fuel tank；Metal cartridge is provided with axial ventilation through hole；In ventilation through hole, that one end outside chain saw fuel tank is provided with the steel ball of activity；It is additionally provided with, in ventilation through hole, the stage clip offseted with steel ball；Wherein, metal cartridge stretches into that one end in chain saw fuel tank and is fixed with the gland offseted with stage clip, and described gland is provided with the pore through with through hole of ventilating.After the air pressure in chain saw fuel tank reduces, extraneous air overcomes the resistance of spring and steel ball, realizes internal and external pressure balance in entering chain saw fuel tank, wherein, metal cartridge, steel ball and stage clip are metalwork, so that this balancer mechanism is difficult to aging, service life is long, stable performance.
