Abstract
The purpose of this utility model is to provide a kind of split type actuating device, including cylinder sleeve, piston, tube-shaped piston bar, the disc Magnet of axial charging, axial charging circular ring magnet, its construction is：Fixed wafer shape Magnet on piston within cylinder sleeve, clamping rings shape Magnet on outer tubular piston rod, so that disc Magnet can just be stablized in annular magnet Centromedian dynamic balance position, make linkage inside and outside it using magnetic force, thus reach making piston and piston rod be placed in inside and outside purpose, for γ type Stirling engine, the dynamic sealing of piston rod can be saved.
Description
Art
This utility model is related to a kind of actuating device, the transmission dress that specifically can be placed in inside and outside by piston and piston rod
Put.
Background technology
In currently known Stirling engine, piston and piston rod are one, and piston rod needs oil-free dynamic sealing, close
Envelope is complicated, and working medium easily leaks.
Content of the invention
In order to overcome existing piston stirling engine rod seal difficult, the defect of working medium easily leakage, this utility model
There is provided a kind of piston, piston rod can be placed in inside and outside method, for the gas distribution piston of γ type Stirling engine, can save
Go the dynamic sealing of piston rod.
This utility model be employed technical scheme comprise that, a kind of split type actuating device, lives including cylinder sleeve, piston, tubulose
Stopper rod, the wafer type strong magnet of axial charging, the circular ring type strong magnet of axial charging, is characterized in that：On piston within cylinder sleeve
Fixed wafer shape Magnet, clamping rings shape Magnet on outer tubular piston rod, make that the thickness of two blocks of Magnet is identical, heteropole is same
Direction, now disc Magnet can just stablize in circular ring magnet Centromedian dynamic balance position, made inside and outside it using magnetic force
Linkage, thus reach make piston and piston rod be placed in inside and outside purpose.
The beneficial effects of the utility model are, in Stirling engine, can save the sealing part of piston rod, and save
The abrasion causing because of dynamic sealing and energy loss, make simple and stable structure.
Brief description
Figure is structural representation of the present utility model, wherein
1st, piston rod pin
2nd, tubular piston bar
3rd, annular magnet
4th, air inlet/outlet
5th, cylinder sleeve
6th, piston
7th, disc Magnet
8th, piston rod guidance tape
Specific embodiment
Split type actuating device includes cylinder sleeve, piston, tubular piston bar, the wafer type strong magnet of axial charging, axially fills
The circular ring type strong magnet of magnetic, in this device, used material is diamagnetism material in addition to Magnet, and main purpose is only to allow magnetic
Active force is produced, without producing other active forces, concrete grammar is installation piston inside cylinder sleeve, and piston one end is solid between ferrum
Determine, outside disc Magnet, cylinder sleeve, tubulose piston rod, piston rod front end clamping rings shape Magnet are installed, make the thickness of two blocks of Magnet
Identical, heteropole can just be stablized in circular ring magnet Centromedian dynamic balance position in same direction, now disc Magnet, profit
Make inside and outside it linkage with magnetic force, so that piston and piston rod are placed in inside and outside, reach internal completely enclosed effect.
