Specifically, the cylinder head component 50 includes: cylinder head 52, valve plate 53 and suction valve chip 54.Cylinder head 52 and cylinder
Seat 10 connects, and valve plate 53 is arranged between cylinder head 52 and cylinder block 10.Suction valve chip 54 is arranged in valve plate 53 and cylinder block 10
Between.Valve plate 53 can play a supporting role to suction valve chip 54.Suction valve chip 54 is arranged close to piston only 21, Ke Yitong
Suction valve chip 54 is crossed to limit piston only 21.
The cylinder assembly 200 further includes postive stop baffle 40, postive stop baffle 40 be arranged in cylinder block 10 towards driving mechanism
100 side, by postive stop baffle 40 and the cooperation limit of suction valve chip 54, so that piston only 21 is moved between
It is dynamic.
In order to is lubricated to cylinder interior part, it is provided with first on postive stop baffle 40 and gets rid of oilhole 41 and oil leaking hole 42,
First gets rid of oilhole 41 and oil leaking hole 42 is connected to gas flow.It in this way can be by first by the oil liquid that driving section 30 is thrown away
It gets rid of oilhole 41 to enter in cylinder, and drives oil liquid to enter cylinder interior by the movement of piston only 21, then again by positioned at the
One oil leaking hole 42 for getting rid of 41 lower section of oilhole flows out cylinder, and oil liquid is enable to be circulated in cylinder.
Using compressor provided in this embodiment, when driving section 30 is turned to close to 10 part of cylinder block, the second magnetic at this time
Inhale part the magnetic pole towards piston only 21 will the magnetic pole same sex (being all the pole N or S) with piston only 21 towards driving section 30, benefit
Compression and exhaust process are completed with the repulsion power drive piston only 21 between the second magnetic absorption member and the first magnetic absorption member.Work as driving section
When 30 180 ° of rotation, the second magnetic absorption member magnetic pole opposite with the first magnetic absorption member is on the contrary, so i.e. using the second magnetic absorption member at this time
And the expansion completed of the first attraction power drive piston only 21 between magnetic absorption member and breathing process.
The compressor provided through this embodiment, shaft and piston use contactless Magnetic driving, optimize so original
Complicated pump housing drive mechanism, saves the transmitting assemblies such as connecting rod, piston pin, elastic positioning pin.This not only reduces transmission groups
The quantity of part, but also assembly technology is optimized, so that production technology is simpler, production efficiency can be improved.Further, since
It is the Magnetic driving used, therefore the structural material in compressor can use casting aluminium material, can reduce the shadow to magnetic field in this way
It rings, and can reduce the weight of device entirety.
