LOW-PRESSURE STARTER DEVICE FOR PNEUMATIC PUMPS

The invention relates to a low-pressure starter device for pneumatic pumps with a pivoting directional air-control valve, characterised in that the low-pressure starter system consists of a retractable push piston actuated by a variable-tension spring that exerts pressure on the shaft of a pivoting element of the body of the directional valve, during start-up, in an end operating positions, said device being formed by a retractable piston, a sealing gasket, a spring and a spring stop. 本发明涉及一种用于具有枢转换向气控阀的气动泵的低压启动装置，其特征在于：所述低压启动装置包括由可变张力弹簧致动的可伸缩推动活塞，在启动期间，所述弹簧在换向阀主体的枢转元件的轴的端部操作位置施加压力；所述装置由可伸缩活塞、密封垫、弹簧以及弹簧止动件形成。
