Description

The combustion engine inflation pump of meeting an urgent need

The utility model relates to a kind of gas filled device, especially a kind of emergent inflation pump of tire that is applicable to gasoline fueled motor vehicle.

The device that is widely used in the tire carbonation of motor vehicle operation at present has air compressor, or the Electronmotive Force pressure-charge compressor, pin is stepped on inflation pump, onboard, also can be taken at combustion engine is power, but be not easy installing, the position is installed and is not suitable for its complex structure, volume is big, the cost height uses and carries extremely inconveniently, is unfavorable for that vehicle carries out tire patching inflation operation on the way.

The purpose of this utility model is: in multi-cylinder or single cylinder gasoline engine, utilizing the spark-plug hole of cylinder to do the installation site, is power by the pistons work of cylinder, is combined into an inflation pump, it is not limited by electric power supply, can both put on the air for a gasoline fueled motor vehicle tire flat at any time.

Technical solution adopted in the utility model is: connector 1 outer end that the center has gas-discharging channel hole has screw thread up and down, and spring 6 and ball 7 are housed in the hole, road; One end insertion connector 1, center have the drain tap assembly set 2 of gas-discharging channel hole, hole, road built-in spring 4 and ball 3, and its other end connects the gas-charging connection 5 that the center has gas-discharging channel hole.Connector 1 external place also is provided with leakproof air cushion 8.

The utility model structure is very simple, and manufacturing is easy to, and weight is lighter, volume is little, and cost is lower, and is small and exquisite, saves energy portably uses very convenient, economical and practical, tire flat in the way of travelling plays the emergent effect of inflating immediately, and easy and simple to handle, inflation is quick, as long as pin is easily stepped on the engine starting bar, or uses starter to rotate combustion engine, immediately can give tire carbonation of motor vehicle, very laborsaving, be the standing essential instrument of automobile driver.

Elaborate below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

The utility model is by connector 1, attaching parts 2, and ball 3,7, spring 4,6 takes over 5, and leakproof air cushion 8 is formed.

Connector 1 has two ends up and down, and the lower end car has outside thread, interim orbit hole, and leakproof air cushion 8 is arranged outward, is connected with the sparking plug for internal combustion engine hole, and device ball 7, gas spring 6 constitute the first drain tap assembly set in the hole, road.Connector 1 upper end car has negative thread, is used to be right after the attaching parts 2 lower end outside threads of second exhaust assembly.Attaching parts 2 upper end cars have negative thread and gas-discharging channel hole, device has one-way exhaust valve door ball 3 in the hole, road, gas spring 4, be combined into second series air valve assembly set, its upper end car has negative thread, be connected with adapter 5 rear end outside threads, take over 5 front end connecting ducts, form one tire is put on the air.

When combustion engine during at intake stroke, piston is downward, the inlet valve of combustion chamber is opened, barometric pressure sucks cylinder by airfilter, carburettor pipeline, and the piston in the cylinder is normally operation up and down, does not form any negative pressure, air-breathing in the cylinder, piston is when making progress compression stroke, and internal combustion engine intake valve is closed, and piston is to up.When exhaust valve was not opened in combustion chamber, gas was toward upward pressure in the cylinder, and air pressure is pushed jury pump drain tap assembly set open, and discharge and tracheae put on the air to tire.When the combustion engine working stroke, descent of piston, and the exhaust assembly of this inflation pump is to equate with the exhaust valve of combustion chambers of internal combustion engines, be closed condition simultaneously, and the exhaust valve of combustion chambers of internal combustion engines is to rely on the exhaust of doing work of the fixed ignition system of combustion engine and camshaft, piston stroking upward during to top dead point exhaust valve just open fully.This inflation pump exhaust assembly is to utilize that device has valve ball and gas spring structure in the hole, its structure piston apparatus moves the gas spring of air pressure pressure greater than exhaust assembly up and down in cylinder, the gas spring pressure of exhaust assembly is directly proportional less than the pressure in the cylinder, otherwise the pressure in the cylinder that is inversely proportional to pushes away not open, has only piston in work done up and down, cylinder is air-breathing, produce air pressure, exhaust assembly promptly is open at any time and closes, thereby not controlled and the gas of should rehearsing with musical accompaniment by the camshaft of combustion engine.Because should only allow the atmospheric pressure in the cylinder to discharge by anxious inflation pump exhaust assembly device, never allow tire pressure to return to push back and flow to into cylinder.So the piston of combustion engine is transported gas up and down with the door open in cylinder, the piston air pressure that makes progress is pushed exhaust assembly open, plays the exhaust aeration.Because air is to suck by air intake branch and carburettor, cylinder, so there is not any negative pressure, has enough air pressure and comes dummy piston to move air pressure up and down, can not produce the negative pressure resistance and the machine oil that produces in the crankcase is scurried into cylinder.During exhaust stroke, exhaust valve is opened, and piston stroking upward enters freeing pipe to the part mixture gas of input, can not send noise because of burning.Go round and begin again, Here it is, and the utility model---the emergent inflation pump of internal combustion engine moving light-up plug formula double valve is contained on four stroke, the two cycle internal combustion engine, is combined into the principle of work of four stroke, double stroke or the multicylinder four-stroke inflation pump of single-cylinder engine.Be contained on double stroke, the four-cycle, single-cylinder combustion engine by it, at first fuel-feed system closed, mustn't flow into carburettor formation mixture gas by fuel feeding, when inflating Throttle Opening Control is opened entirely, inflate faster, more extensive practical.
