Abstract
The utility model discloses a novel valve which comprises a head, a working section and a non-phase matching working section. The diameter of the non-phase matching working section of the valve is smaller than that of the working section of the valve; and the diameter at the tail of the valve is the same with that of the non-phase matching working section of the valve. The novel valve has the advantages of simple structure, reduction of the light of an engine, improvement of the rotating speed of the engine, and good mechanical properties.
Description
Technical field
The utility model relates to the valve gear that is used for a kind of internal-combustion engine.
Background technique
At present, the valve stem of the inlet and exhaust valve of internal-combustion engine generally adopts same diameter, though this class inlet and exhaust valve device is simple in structure, easy to manufacture, but motor when high speed rotary, inlet and exhaust valve is driven by intake and exhaust mechanism and does high stress alternation motion, when the rotating speed of motor reaches certain high speed, it is very big to act on the inertial force that produces on the inlet and exhaust valve, even produces destruction impulse inertia power, can not satisfy the needs of high performance internal combustion engine.
Summary of the invention
The purpose of this utility model provides a kind of valve.Its weight simple in structure, that can alleviate motor, raising engine speed, good mechanical property.
For achieving the above object, the technical solution of the utility model is: the valve of being made of one head, active section and non-cooperating section, the diameter of the non-active section that matches of valve is less than the diameter of valve active section, and the diameter of valve afterbody is identical with the diameter of the non-active section that matches of valve.After adopting such scheme, the motor related components reduces size simultaneously, therefore can alleviate engine weight, effectively reduces the inertial force that produces, and makes maximum power and maximum speed get a promotion good mechanical property.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a topology view of the present utility model;
Fig. 2 is a kind of embodiment of the present utility model.
Specific embodiments
As shown in Figure 1, form the valve 13 of one by head 1, active section 2 and non-cooperating section 3, the diameter of the non-active section 3 that matches of valve is less than the diameter of valve active section 2, and the diameter of valve afterbody 5 is identical with the diameter of the non-active section 3 that matches of valve.Be provided with rod slot 4 by the tail end place, rod slot 4 is the R groove.
As shown in Figure 2, be that example illustrates working procedure of the present utility model with the motorcycle engine.
The shape of valve head 1 and valve seat 7 are suitable.Valve middle part 2 is the identical cylindrical body of diameter, and valve head 1, valve middle part 2, the non-active section 3 that matches of valve, valve afterbody 5 are same medial axis.Valve seat 7 is embedded on the engine cylinder head 6, valve head 1 is placed in the valve seat 7, the shape of valve head 1 and valve seat 7 are suitable, valve guide bushing 8 is enclosed within valve middle part 2 and is connected with engine cylinder head 6, valve guide bushing 8 is an interference fit with engine cylinder head 6, valve guide bushing 8 links to each other with following 9 of valve spring, lay valve spring 10 on following 9 of the valve spring, the valve spring seat of honour 11 is installed in the position of the non-active section 3 that matches of valve of valve 13, be connected with valve afterbody 5 by locker 12, locker 12 pins rod slot 4.
Claims (4)
1. novel valve, form one by head (1), active section (2) and non-cooperating section (3), it is characterized in that: the diameter of the non-active section that matches of valve (3) is less than the diameter of valve active section (2), and the diameter of valve afterbody (5) is identical with the diameter of the non-active section that matches of valve (3).
