On turntable.Shaft coupling is formed by axle sleeve, connecting rod and plunger so that turntable, which rotates, drives plunger to move back and forth, and can keep away
Exempt from plunger to rotate.
Preferred embodiment two：Based on preferred embodiment one, the cooling duct is set in the shape of a spiral.It can be so that cooling water cooling down
In passage, become larger to the heat exchange area of plunger and the cooling water in feed pathway, so that cooling is better.
Preferred embodiment three：Based on preferred embodiment two, the cylinder body is equipped with several air holes.Air hole can distribute heat
Amount cools down to plunger and feed pathway.
Preferred embodiment four：Based on preferred embodiment three, the baffle runs through cylinder body, and the one end of baffle away from air bag is connected with
Stop plate.By expanding with heat and contract with cold for air bag, realize the movement of baffle, so as to stop the movement of plate, realize the opening of air hole with
It closes.
