Description
Technical field
The present invention relates to a kind of compressors.
Background technique
Compressor is a kind of driven fluid machinery that medium is promoted to high pressure from low pressure, and existing compressor is mostly to live
Plug structure, piston is mobile in one direction to extrude medium, and reversed return then sucks medium, i.e. the output of compressor is intermittent
Or pulsed, there are rooms for improvement.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of compressors for being always maintained at and stablizing and exporting.
To achieve the above object, the present invention provides a kind of compressors, include shell and shaft, pressure is provided on shell
Contracting chamber, is additionally provided with the medium manhole appendix being connected with compression chamber on shell, and the outer end of shaft is connected with the dynamic of driving its rotation
The inner end in power source, shaft is inserted into the compression chamber of shell, and is set with the first turning set and the second turning set, the first turning set
On be extended with the first convex block, and the radial outer end of the first convex block and axial ends are kept in contact with compression cavity wall, second turn
Dynamic put on is extended with the second convex block, and the radial outer end of the second convex block and axial ends are kept in contact with compression cavity wall, institute
Stating to be provided in compression chamber rotates a convex block in the first and second convex block with shaft, and switches after convex block rotation is turned around
The switching mechanism rotated to another convex block with shaft.
The beneficial effects of the present invention are: using the above structure, since the present invention is set on the inner end of the shaft
One turning set and the second turning set are extended with the first convex block, and the radial outer end of the first convex block and axial two on the first turning set
End is kept in contact with compression cavity wall, and the second convex block, and the radial outer end and axis of the second convex block are extended on the second turning set
It is kept in contact to both ends with compression cavity wall, therefore the first convex block and the second convex block can correspond to compression chamber being separated into two chambers
Room.When work, under the action of switching mechanism, a convex block in the first and second convex block is first rotated with shaft, when the convex block rotates
Another convex block is switched to after one circle to rotate with shaft, is so recycled, thus effectively ensure to there is a convex block to rotate with shaft always,
Another convex block then remains stationary, and the principle switched after rotation is turned around and mutually holds two chambers in compression chamber to realize
Long-pending change, so that compression function provided by the invention is always maintained at stable output, i.e., the present invention is a constant current mode
Compressor.In addition, the direct switching that medium passes in and out direction can be realized by the rotation direction for changing shaft.
It includes the first grafting block and the second grafting block that the present invention, which can be further arranged to the switching mechanism, on the first convex block
The first through slot radially penetrated through is offered, the first grafting block radial slippage is arranged in the first through slot, and the diameter of the first grafting block
It is greater than the radical length of the first through slot to length, offers the second through slot radially penetrated through, the second grafting block diameter on the second convex block
To sliding in the second through slot, and the radical length of the second grafting block is greater than the radical length of the second through slot, right in the shaft
It should be provided with the interior slot being radially-inwardly inserted into for the first grafting block or the second grafting block, correspondence is set on the inner wall of the compression chamber

When connecing cooperation, the second grafting block is separated with outer slot, and is inserted into interior slot；When the second grafting block and outer slot constitute grafting
When cooperation, the first grafting block is separated with outer slot, and is inserted into interior slot.
Using the above structure, shaft rotates under the drive of power source, if initial position is the first grafting block and interior slot
It plugging, the second grafting block is plugged with outer slot, then the first convex block and the first turning set will follow shaft to rotate together, and
The second convex block and the second turning set are then fixed at this time, thus with the rotation of the first convex block, the first convex block and the second convex block
The one of cavity volume being separated to form constantly becomes larger, and the volume of another chamber constantly becomes smaller, and then realizes to medium
Compression.After the rotation of the first convex block is turned around, the first convex block can collide with the second convex block, so that the rotation of the second convex block is pushed,
Even if the second grafting block on the second convex block is separated with outer slot, and is inserted into interior slot, and first on the first convex block inserts
It connects block then to skid off from interior slot, and mating with outer slot composition, hereafter the second convex block and the second turning set are with shaft
It rotates together, and the first convex block and the first turning set are then fixed at this time, is switched to the again after the rotation of the second convex block is turned around
The rotation of one convex block, so recycles.
The present invention may further be provided integrally formed with disk on the inner end for shaft, and the interior slot is provided with disk
Outer circumference surface on, the first turning set and the second turning set set up the axial sides in disk separately.In this way, structure is more symmetrical
Rationally, stability is more preferable in rotation process.
The present invention may further be provided between axial one end end face of the first turning set and disk, the first turning set
Between axial the other end face and compression cavity wall, between the axial one end end face and disk of the second turning set, the second turning set
Axial the other end face and compression cavity wall between be provided with sealing ring.Setting overall tightness in this way is more preferable, to have
Help better compressed media.
The present invention, which may further be provided, to be axially spliced to form for the shell by upper housing, middle shell and lower case, institute
The outer slot stated is provided on middle shell.Not only assembly is more convenient for setting in this way, but also even if outer slot is damaged, also only needs
Shell in replacement, substantially reduces maintenance cost.
The present invention may further be provided to be inclined to set for the two sides of interior slot and the two sides of outer slot.In this way
Setting facilitates the insertion of the first and second grafting block and skids off.
The present invention may further be provided between the first turning set and shaft and between the second turning set and shaft
It is provided with bearing.Setting is more conducive to the rotation of the first and second turning set in this way.
