In, piston bush 33 only circles, and 32 one side of piston is moved back and forth relative to sub- shaft 10, while again relative to piston
The pilot hole 311 of set 33 moves back and forth, and two reciprocating motions are mutually perpendicular to and carry out simultaneously, to make the reciprocal of both direction
Movement constitutes cross slides motion mode.The compound motion of this type cross slides makes piston 32 relative to piston bush
33 is reciprocating, and the cavity which form piston bush 33, cylinder and piston 32 periodically becomes larger, reduces.And
Piston 32 is circled relative to cylinder, the capacity chamber 31 which form piston bush 33, cylinder and piston 32
Periodically it is connected to air inlet 21, exhaust outlet 22.Under the collective effect of two above relative motion, keep compressor complete
At air-breathing, the process of compression, exhaust.In the process of reciprocating, the centroid trajectory line of piston 32 is circle, and circular diameter is equal to
Eccentric amount e, the center of circle is on the center of sub- shaft 10 and the midpoint of the line of centres of piston bush 33.
