Abstract
The invention provides a self-lubricating electromagnetic driver. According to the scheme, the self-lubricating electromagnetic driver comprises a pin sleeve and a valve shell installed on the pin sleeve. Electromagnetic driver bodies are fixedly installed in the valve shell, and valve pins are installed in the pin sleeve. The electromagnetic driver bodies make contact with the valve pins and can drive the valve pins to move. The valve pins comprise sliding parts, shrinking parts and stretching-out parts. The sliding parts can slide axially along the inner wall of the pin sleeve. The shrinking parts are arranged in the middles of the valve pins and concaved inwards in the radial direction. An oil storage cavity is formed between the shirking parts and the interior of the pin sleeve. The stretching-out parts are smaller than the sliding parts and larger than the shrinking parts. By means of the scheme, the response speed of an electromagnetic valve can be increased; meanwhile, maintenance cost can be saved, and the fault rate of the electromagnetic valve can be reduced.
Description
Technical field
What the present invention relates to is a kind of solenoid valve, especially a kind of selflubricating electromagnetic driver.
Background technique
In the electromagnetic driver of the valve lift amount of previously known adjustment motor, can rotate integrally with axle it is known that change, and the position of the slide block axially moved relative to this axle along axle.Electromagnetic driver is the driving mechanism driving slide block movement, and it controls to drive relative to axle axial motion according to the signal that engine controller sends.To realize the movement of axial slider, thus realize the object of modulating valve lift.
But the electromagnetic driver of prior art has following risk: the lubrication 1, between electromagnetic driver valve pin and guide is inadequate, and valve pin works and occurs the risk of inordinate wear in guide; 2, valve pin head and guide gap less than normal, have the risk of clamping stagnation.
Summary of the invention
Object of the present invention, be exactly for the deficiency existing for prior art, and a kind of technological scheme of selflubricating electromagnetic driver is provided, the program effectively can solve the problem of valve pin head clamping stagnation, automatically can also lubricate valve pin simultaneously, prevent and occur that valve pin works the situation occurring wearing and tearing in guide.
This programme is achieved by the following technical measures:
A kind of selflubricating electromagnetic driver, include guide and be arranged on the valve shell on guide, valve shell internal fixtion is installed by electromagnetic driver, is provided with valve pin in guide; Electromagnetic driver contacts with valve pin, and valve pin can be driven to move; Valve pin includes slide part, contraction flow region and extension; Slide part can slide axially along guide inwall; Contraction flow region to be arranged in the middle part of valve pin and radially to cave inward; Contraction flow region and guide inside form shoe cream room; The size of extension is less than the size of slide part; The size of extension is greater than the size of contraction flow region.
Preferred as this programme: be provided with oil leab in guide; Oil leab is communicated with shoe cream room.
Preferred as this programme: the quantity of contraction flow region is multiple.
Preferred as this programme: when valve pin reaches limit position, extension stretches out guide just completely.
Preferred as this programme: the working surface of the extension of valve pin is cambered surface.
Preferred as this programme: extension can both be contained in guide inside completely when valve pin reaches limit position or reset to limit position.
The beneficial effect of this programme can be learnt according to describing of such scheme, owing to adopting in this scenario, contraction flow region is set on valve pin, contraction flow region and guide inwall form shoe cream room, can import in shoe cream room by lubricant oil, so just can lubricate valve pin in valve pin movement process; The size being dimensioned slightly smaller than slide part of valve pin extension, can make to there is certain gap between extension and guide wall, prevent the phenomenon of extension generation clamping stagnation, the response efficiency of solenoid valve can be significantly improved, avoid the generation of fault, save Maintenance and Repair cost.
As can be seen here, the present invention compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent.

Fig. 3 is the structural representation of valve pin.
In figure, 1 is guide, and 2 is valve shell, and 3 is electromagnetic driver, and 4 is valve pin, and 5 is extension, and 6 is slide part, and 7 is contraction flow region, and 8 is shoe cream room.
Embodiment
For the technical characterstic of this programme can be clearly demonstrated, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
Can be found out by accompanying drawing, this programme includes guide and is arranged on the valve shell on guide, and valve shell internal fixtion is installed by electromagnetic driver, is provided with valve pin in guide; Electromagnetic driver contacts with valve pin, and valve pin can be driven to move; Valve pin includes slide part, contraction flow region and extension; Slide part can slide axially along guide inwall; Contraction flow region to be arranged in the middle part of valve pin and radially to cave inward; Contraction flow region and guide inside form shoe cream room; The size of extension is less than the size of slide part; The size of extension is greater than the size of contraction flow region.Oil leab is provided with in guide; Oil leab is communicated with shoe cream room.The quantity of contraction flow region is multiple.When valve pin reaches limit position, extension stretches out guide just completely.The working surface of the extension of valve pin is cambered surface.Extension can both be contained in guide inside completely when valve pin reaches limit position or reset to limit position.
Form shoe cream room between the contraction flow region arranged in the middle part of valve pin in this programme and guide, shoe cream room is connected with the oil leab in guide, when valve pin moves, can play lubrication to valve pin, prevent valve pin from wearing and tearing; The size being dimensioned slightly smaller than slide part of extension, makes to have certain gap between extension and guide inwall simultaneously, when can prevent valve pin from moving, catching phenomenon occurs.
This programme can improve the speed of response of solenoid valve, can save maintenance cost simultaneously, reduces the rate of fault of solenoid valve.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
