Abstract
The utility model discloses an axial flow air inlet mechanism of a two-stroke engine. The axial flow air inlet mechanism comprises a crankshaft and a shaft sleeve, and relative motion exists between the crankshaft and the shaft sleeve; a through hole is opened on the shaft sleeve; the crankshaft is a hollow shaft; and a connecting hole is opened at a position matched with the through hole of the shaft sleeve on the crankshaft, and the connecting hole connects the through hole of the shaft sleeve with the hollow portion of the crankshaft to form an axial flow valve air inlet channel. When the connecting hole on the crankshaft is communicated with the through hole on the shaft sleeve, air-fuel mixture begins to be fed for preparation of work next time. The axial flow valve air inlet can be achieved by means of the axial flow air inlet mechanism.
Description
Technical field
The utility model relates to a kind of motor, is specifically related to a kind of axial flow admission gear of two stroke engine.
Background technique
Existing two stroke engine, its intake method is general adopts two kinds, and a kind of is piston-valve induction, and another kind is reed valve induction.All there is certain deficiency in these two kinds of intake methods.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of axial flow admission gear of two stroke engine, and it can realize the axial flow valve air inlet.
For solving the problems of the technologies described above, the technical solution of the axial flow admission gear of the utility model two stroke engine is:
Comprise bent axle, axle sleeve, have relative movement between bent axle and axle sleeve; Have through hole on axle sleeve; Bent axle is a hollow shaft; An attachment hole is opened in the position that is complementary with the through hole of axle sleeve on bent axle, and this attachment hole is connected the through hole of axle sleeve with the hollow part of bent axle, forms the axial flow valve gas-entered passageway.
The external Carburetor of through hole on described axle sleeve.
Described bent axle rotates, and when through hole on axle sleeve communicates, begins to be filled with air-fuel mixture gas, for work done is next time prepared when the attachment hole on bent axle.
The technique effect that the utility model can reach is:
The utility model can be realized the axial flow valve air inlet.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the schematic diagram of the axial flow admission gear of the utility model two stroke engine;
Fig. 2 is the right elevation of Fig. 1.
Description of reference numerals in figure:
1 is bent axle, and 2 is axle sleeve.
Embodiment
As shown in Figure 1 and Figure 2, the axial flow admission gear of the utility model two stroke engine comprises bent axle 1, axle sleeve 2, has relative movement between bent axle 1 and axle sleeve 2;
Have through hole on axle sleeve 2;
Bent axle 1 is a hollow shaft; An attachment hole is opened in the position that is complementary with the through hole of axle sleeve 2 on bent axle 1, and this attachment hole is connected the through hole of axle sleeve 2 with the hollow part of bent axle, forms the axial flow valve gas-entered passageway;
The external Carburetor of through hole on axle sleeve 2.
Working principle of the present utility model is as follows:
Bent axle 1 rotates, and when through hole on axle sleeve 2 communicates, namely begins to be filled with air-fuel mixture gas, for work done is next time prepared when the attachment hole on bent axle 1.
