提出一种新型摇摆活塞式无油润滑空气压缩机，利用活塞摇摆运动时与气缸形成的侧隙构成进气通道，并利用曲轴箱作为压缩机的进气消声室。新机型摒弃了易损件进气簧片阀，拓展了进气消声器容积，与传统摇摆活塞机型相比无故障工作时数提高约119／6、噪声降低约5～6dB（A）。研究表明，气缸向压缩行程一侧适当偏置，同时辅以较大数值的曲柄连杆比λ，可以实现活塞侧隙进气，并能确保压缩行程时密封环对气缸的密封性，另外还可减小压缩机的体积；但是，为了缓解活塞对气缸的敲击，必须设置缓冲装置，而且需要强化连杆的散热和隔热，以减小连杆轴承的温升。

This paper proposed a new type wobble piston oil--free air compressor, in which the side gap between piston and cylinder, formed by the piston swing to the cylinder, was used as inlet port for the compressor and the cavity of crankcase was used as the intake silencer. The new compressor has abandoned damageable part suction reed valve and expanded the volume of the intake muffler, so that the compressor has increased trouble--free working life by about 11% and reduced noise by about 5--6dB（A）,compared with traditional models. The results show that when the cylinder offsets appropriately toward compression stroke side, and supplement the larger values of crank radius--con- necting rod length ratio λ, at the same time, suction can be realized through the side gap, thus ensuring the tightness of the seal ring toward the cylinder on the compression stroke and reducing the volume of the compressor. However, in order to decrease the impact strength of the piston to the cylinder, it is necessary to set a buffer device,and to strengthen the cooling and insulating for connecting rod to reduce the temperature rise of bearing.
