Abstract

One kind can prevent the reasons such as automobile encounters the quick fuel feeding of collision accident, dynamical system or climate change is expanded with heat and contract with cold, when leading to that positive pressure or negative pressure are beyond normal range (NR) in fuel piping system, the leakage of lubricator positive pressure and negative pressure compensating device.It is by lubricator upper case 1, (filling conduit) rubber seal 2, diversion trench 3 and to be designed to that the upper and lower hermatic door of rotary valve structure constitutes enclosed construction；And be arranged in upper and lower hermatic door and vertically suppress valve mechanism, the valve mechanism that vertically suppresses is made of the upper cover 4/11 of two sides setting gas vent, hermatic door rubber seal 5/12, spring 6, valve block 7, the lower cover 8/13 of bottom belt valve opening, sealing door pivot 9/14, hermatic door spring 10 etc..When automobile encounters the quick fuel feeding of collision accident, dynamical system or climate change is expanded with heat and contract with cold, when leading in fuel piping system positive pressure or negative pressure increase beyond normal range (NR), valve opening of the positive air pressure through lubricator hermatic door lower cover 8/13, push the valve block 7 suppressed by spring 6 open, then the two sides gas vent through upper cover 4/11 loses heart；Or negative pressure suction opens and is designed to that the upper and lower hermatic door sucking air of changeover valve compensates, and has reached the function of positive pressure leakage and negative pressure compensating device.

Description

The leakage of lubricator positive pressure and negative pressure compensating device
Technical field
The invention patent relates to a kind of leakage of oil filler for automobiles positive pressure and negative pressure compensating devices.It is characterized in that by vehicle fuel The upper case of pipeline and lubricator, rubber seal, diversion trench and the upper and lower hermatic door for being designed to valve mechanism etc. are constituted Closed structure, and setting vertically suppresses valve mechanism in the inside of upper and lower hermatic door, it is described vertically to suppress valve mechanism by two sides Upper cover, hermatic door rubber seal, spring, the valve block, the lower cover of bottom belt valve opening, sealing door pivot, sealing of gas vent are set The compositions such as door spring constitute positive pressure leakage and the negative pressure compensating device of lubricator.
Background technique
Currently, automobile fuel oil pipeline system is all made of and is closed completely structure, when to encounter collision accident, dynamical system fast for automobile Fast fuel feeding or climate change such as are expanded with heat and contract with cold at the reasons, and positive pressure or negative pressure in fuel piping system can be made to cause beyond normal range (NR) The problems such as explosive combustion accident or fuel piping system malformation damage, vehicle service life are caused to shorten.
Summary of the invention
When in order to make automobile encounter the reasons such as the quick fuel feeding of collision accident, dynamical system or climate change, fuel oil is prevented Positive pressure or negative pressure exceed normal range (NR) in pipeline, and the invention patent invents a kind of lubricator positive pressure leakage and negative pressure compensating device. The invention patent solves technical solution used by its technical problem: the upper and lower hermatic door of lubricator is designed to rotary valve Door machine structure, and in the inside of hermatic door, setting vertically suppresses valve mechanism, constitutes the positive pressure leakage device of lubricator；Work as fuel pipe When positive air pressure exceeds normal range (NR) in the system of road, from the valve opening of hermatic door lower cover, the valve block by spring suppression is pushed open, through upper cover Two sides gas vent loses heart；When negative pressure exceeds normal range (NR) in fuel piping system, suction, which is opened, is designed to rotary valve structure Hermatic door sucks outside air, carries out negative pressure compensating function.
Detailed description of the invention
Figure of description 1 is the lubricator external structure of the invention patent, and Fig. 2 is the lubricator of the invention patent or more Hermatic door cross-sectional view, Fig. 3 are the hermatic door decomposition charts of the invention patent.
Specific embodiment
The specific embodiment of the invention patent is: hermatic door upper and lower in lubricator is designed to rotary valve structure, and In the inside of the upper and lower hermatic door of lubricator, setting vertically suppresses valve mechanism, described vertically to suppress valve mechanism by setting valve opening Lower cover, valve block, spring and two sides setting gas vent upper cover composition；When positive pressure in fuel piping system or negative pressure are beyond normal When range, valve is vertically suppressed in positive air pressure starting hermatic door, carries out positive pressure leakage；Or negative pressure starting is designed to changeover valve Hermatic door suck air, carry out negative pressure compensating.To reach guarantee automotive safety, prevent explosive combustion or gradually pressure release delay it is quick-fried Fried burning increases the life rescue time, and the purpose for preventing fuel system malformation from damaging.
