METHOD OF AIR INFLATING INTO AIR CASE OF HYDRAULIC RAM PUMP Russian patent published in 2014 - IPC F04F7/02 

FIELD: motors and pumps.

SUBSTANCE: method of air inflating into air case 5, 6 of hydraulic ram pump consists in that air is supplied into the working camera 11, 12 of the working section 3, 4 of the supply pipeline connected with the air case 5, 6, and air flow rate through the air duct tube 13, 14 is monitored, one end of which is connected with the active nozzle 9, 10 of the working camera 11, 12, and another one - with atmosphere. At the moment of achieving of preset air volume in the case 5, 6, corresponding to the pressure head operating mode, air supply is stopped. Air source is designed as an air trap camera 21, 22, with the working camera 11, 12 and by means of the water discharge tube 31, 32, with the executive unit 33, 34 with the valves 35, 36 with the air case 5, 6.
