Cylinder block can be reduced and air compressor machine of deformation is screwed up

The utility model discloses a cylinder block can be reduced and air compressor machine of deformation is screwed up, it includes cylinder block, cylinder liner and cylinder cap, and cylinder liner outside cover is equipped with the packing ring, is equipped with the cylinder in the cylinder block, and the cylinder liner lies in the cylinder, and the packing ring lies in between cylinder and the cylinder liner, and the cylinder cap bottom is equipped with the gasket, and the edge of cylinder cap passes through the bolt spiro union in the cylinder block, and the gasket of cylinder cap bottom andthe top pressfitting of cylinder liner are together. The utility model discloses the tightening force square that makes the bolt transmit not to on the cylinder liner perhaps only very little power and can transmit to the cylinder liner on to reduce the cylinder liner in the cylindricity deviation of work in the engineering, thus can reduce the air compressor machine along with gas oil extractionvolume and gas blowby vol
