Beschreibung
Zusammenfassung:	The invention relates to a hydro-pneumatic pumping installation. The installation comprises a double acting hydro-pneumatic booster 2, the pneumatic chambers 3, 4 of which are connected with respective outlets of a pneumatic power distributor 7. The hydraulic chambers of the booster 2 are connected with an actuating hydraulic engine 1 through a power and a drain line 14 and 15, respectively. The pumping installation further comprises a hydro-pneumatic accumulator 22 connected to the power line 14. The booster 2 is provided with pneumatic limit switches 26, 27. The pumping installation further comprises a single-acting hydro-pneumatic booster 30 provided with a pneumatic limit switch 33. The pneumatic chambers 30a, 30b of the latter booster 30 are connected with respective outlets of a four-line two-position pneumatic distributor 34.
