Description
Technical field
The present invention relates to ftercompction systems technology field, relate in particular to a kind of motor ftercompction system.
Background technique
In order to improve the overall performance of motor, usually use ftercompction system to compensate pressure to motor.The employing motor-drive pump that tradition ftercompction system has carries out ftercompction, and some employing mechanical structure is carried out ftercompction, but traditional ftercompction system exists short shortcoming of complex structure, poor, the stable performance of ftercompction effect, working life.
Summary of the invention
The object of the invention is to for the problems referred to above deficiency, a kind of motor ftercompction system is provided, have advantages of that compensation engine pressure, ftercompction are effective, stable, long service life, simple in structure.
In order to achieve the above object, the present invention is by the following technical solutions:
Motor ftercompction system, is located at cylinder interior, and it comprises valve body, and it is located between cylinder body and piston rod and is circular, and this valve body is divided into storage pressure chamber by cylinder interior and is located at the piston chamber of piston head end; Spring stop collar, it is socketed on storage pressure chamber inner piston rod and is circular; Returnning spring, it is located at the storage pressure chamber between valve body and spring stop collar; Valve opening, it is located on valve body and connects storage pressure chamber and piston chamber; Link block, it coordinates valve opening sealing and tapered post.
Between described valve body and spring stop collar, be provided with a seal ring.
Described seal ring is O-ring seals.
Described link block one end for corresponding with Returnning spring endoporus coordinate and cylindrical spring portion, middle-end for coordinating valve opening sealing and tapered cone seal portion, the other end for being located in valve opening for playing the guiding role and cylindrical guide portion.
When piston head self pressure-storage Shi Wang piston chamber direction moves and when piston link is separated with link block, the cone seal portion of link block fits tightly with valve opening under the active force of Returnning spring, now in sealing state, sealing completely between storage pressure chamber and piston chamber.
When piston head moves and when piston link and link block are collided toward storage pressure chamber direction from piston chamber, Returnning spring is squeezed, link block moves toward storage pressure chamber direction in the active force Xia Zi of piston link piston chamber, between the cone seal portion of link block and valve opening, form gap, now in storage pressure chamber and piston chamber's breakthrough status, under the active force of piston head extruding, storage pressure chamber internal gas circulates toward piston chamber.
When piston head self pressure-storage Shi Wang piston chamber direction moves and when piston link and link block are collided, Returnning spring is squeezed, link block self pressure-storage Shi Wang piston chamber direction under the active force of piston link moves, between the cone seal portion of link block and valve opening, still there is gap, now still in storage pressure chamber and piston chamber's breakthrough status, under the active force of piston head extruding, storage pressure chamber internal gas continues the circulation toward piston chamber.
To store up pressure chamber internal gas Beng Wang piston chamber, play the effect of compensatory pressure.
The present invention adopts said structure, has advantages of that compensation engine pressure, ftercompction are effective, stable, long service life, simple in structure.

Embodiment
As shown in Figures 1 to 6, motor ftercompction system of the present invention, is located at cylinder body 1 inside, and it comprises valve body 7, and it is located between cylinder body 1 and piston rod 2 and is circular, and this valve body 7 is divided into storage pressure chamber 6 by cylinder body 1 inside and is located at the piston chamber 5 of piston head 3 ends; Spring stop collar 12, it is socketed on storage pressure chamber 6 inner piston rods 2 and is circular; Returnning spring 9, it is located at the storage pressure chamber 6 between valve body 7 and spring stop collar 12; Valve opening 11, it is located on valve body 7 and connects storage pressure chamber 6 and piston chamber 5; Link block 8, it coordinates valve opening 11 sealing and tapered posts.
Between described valve body 7 and spring stop collar 12, be provided with a seal ring 10.
Described seal ring 10 is O-ring seals.
Described link block 8 one end for corresponding with Returnning spring 9 endoporus coordinate and cylindrical spring portion, middle-end for coordinating valve opening sealing and tapered cone seal portion, the other end for being located in valve opening for playing the guiding role and cylindrical guide portion.
When move and when piston link 4 is separated with link block 8 toward piston chamber's 5 directions piston head 3 self pressure-storage chambers 6, the cone seal portion of link block 8 fits tightly with valve opening 11 under the active force of Returnning spring 9, now, in sealing state, between storage pressure chamber 6 and piston chamber 5, seal completely.
When piston head 3 moves and when piston link 4 is collided with link block 8 toward storage pressure chamber 6 directions from piston chamber 5, Returnning spring 9 is squeezed, link block 8 moves toward storage pressure chamber 6 directions in the active force Xia Zi of piston link 4 piston chamber 5, between the cone seal portion of link block 8 and valve opening, form gap, now in storage pressure chamber 6 and piston chamber's 5 breakthrough status, under the active force of piston head 3 extruding, storage pressure chamber 6 internal gas are toward piston chamber's 5 circulations.
When move and when piston link 4 is collided with link block 8 toward piston chamber's 5 directions piston head 3 self pressure-storage chambers 6, Returnning spring 9 is squeezed, move toward piston chamber's 5 directions link block 8 self pressure-storage chamber 6 under the active force of piston link 4, between the cone seal portion of link block 8 and valve opening, still there is gap, now still in storage pressure chamber 6 and piston chamber's 5 breakthrough status, under the active force of piston head 3 extruding, storage pressure chamber 6 internal gas continue the circulation toward piston chamber.
To store up pressure chamber 6 internal gas Beng Wang piston chamber 5, play the effect of compensatory pressure.
The present invention adopts said structure, has advantages of that compensation engine pressure, ftercompction are effective, stable, long service life, simple in structure.
More than illustrate and unrestricted technological scheme of the present invention, every technology that does not depart from spirit of the present invention, all belongs within the scope of claim of the present invention.
