Beschreibung
Zusammenfassung:	The invention discloses a lubricant channel structure between an air cylinder hood and an air cylinder head. The air cylinder hood is assembled above the air cylinder head. A positioning pin is a hollow pin. The upper portion of the positioning pin is sleeved with a sealing ring. The sealing ring is arranged in an installing groove in the bottom face of the air cylinder hood. The bottom face of the sealing ring is attached to the top face of the air cylinder head. The air cylinder head is provided with a straight lubricant channel and an inclined lubricant channel, and the upper end of the straight lubricant channel is communicated with the lower end of a positioning pin center hole. The middle of the straight lubricant channel is communicated with a bolt installing hole in the air cylinder head through the inclined lubricant channel. The air cylinder hood is provided with an inclined lubricant channel and a horizontal straight lubricant channel, the lower end of the inclined lubricant channel is communicated with the upper end of the positioning pin center hole, and the upper end of the inclined lubricant channel is communicated with one end of the horizontal straight lubricant channel. The positioning pin serves as one part of a lubricant channel, accordingly, the structure is effectively simplified, the positioning pin is sleeved with the sealing ring, and reliable sealing can be achieved.
