Abstract
The utility model discloses a tilting type miniature four-stroke gasoline engine, comprising a horizontal vertical shaft miniature four-stroke gasoline engine; a fuel tank (6) is communicated with a carburetor (10) through a membrane type oil pump (1) which is arranged on the body case of the gasoline engine; the oil inlet (2) of the oil pump is connected with the oil outlet (5) of the fuel tank (6) through an oil inlet pipe (4); the oil outlet (13) of the oil pump is connected with the oil inlet (9) of the carburetor through an oil outlet pipe (8); a power takeoff port (11) is arranged on one side of the intake port of the air cylinder (12) of the gasoline engine and connected with the power input port (3) of the membrane type oil pump (1) through an admission pipe (7). The tilting type miniature four-stroke gasoline engine has the advantages of simple structure and convenient installation and makes use of the power of the gasoline engine as the driving force of the oil pump to the suck gasoline in the fuel tank into the oil pump, thereby avoiding scuffing of cylinder bore in large angle tilting of the gasoline engine, guaranteeing the normal working of the gasoline engine and prolonging the working life of the gasoline engine.
Description
Technical field
The utility model relates to petrol engine, is specifically related to a kind of tilting-type mini four-stroke gasoline engine.
Background technique
During general horizontal vertical shaft mini four-stroke gasoline engine proper functioning, its piston is near level, and the angle of inclination is little.When petrol engine needs wide-angle tilt work, two problems can appear in this moment: the one, and the fuel feeding problem, under the normal state, the petrol engine oil tank liquid level is higher than Carburetor, the gravity that relies on oil is to the Carburetor gasoline feed, when in case machine tip occurring and causing that the gasoline face is lower than Carburetor in the fuel tank, just can not normal fuel injection; Another is a lubrication problem, when proper functioning, lubricant oil is in the machine case bottom, and the oil thrower of its configuration can be thrown to lubricant oil in the cylinder body, and after machine tip, lubricant oil is not at housing bottom, but flowing to the housing lowest part, this moment, oil thrower was inoperative, caused lubricated insufficient, pull-cylinder phenomena occurs, even damage petrol engine.
Summary of the invention
The purpose of this utility model is: a kind of tilting-type mini four-stroke gasoline engine is provided, and petrol engine guarantees the petrol engine proper functioning when wide-angle tilt, scuffing of cylinder bore no longer occurs and damages the petrol engine phenomenon.
Technical solution of the present utility model is: comprise horizontal vertical shaft mini four-stroke gasoline engine, it is characterized in that: fuel tank is communicated with Carburetor by the membrane flap type oil pump, the membrane flap type oil pump is installed on the petrol engine housing, the filler opening of pump connects the fuel tank oil outlet by oil pipe, the oil outlet of pump connects the Carburetor filler opening by oil outlet tube, intakeport one side at the cylinder of petrol engine is established the power delivery outlet, and the power delivery outlet connects the power inlet opening of membrane flap type oil pump by sucking pipe.
Be with oil skipper on the connecting rod gland in the tilting-type mini four-stroke gasoline engine of the present utility model, petrol engine.
During petrol engine work, when being in suction condition, oil feed pump provides power, gasoline in the fuel tank is drawn onto in the oil pump, utilize the membrane flap type oil pump that gasoline in the pump is discharged by oil outlet then and enter into Carburetor, move in circles like this, guarantee that the regular supply of gasoline energy is in Carburetor in the fuel tank.
When petrol engine tilted, lubricant oil focused on the housing lowest order, and in the connecting rod rotation process, the oil skipper of connecting rod gland is thrown to lubricant oil in the cylinder body, guaranteed normally lubricated.
The utility model is simple in structure, and is easy for installation, utilizes the driving force of petrol engine power as oil pump, and gasoline in the fuel tank is drawn in the oil pump, and the pull-cylinder phenomena when avoiding the petrol engine wide-angle tilt guarantees the petrol engine proper functioning, prolongs the petrol engine operating life.
