    摘要: A piston pump for submerging in an oil well, consisting of four pistons that, by means of a fixed interlock (105) between two opposing pistons and a cog wheel interlock (104) between these and the two other pistons, get two oncoming piston pairs in which the mass forces are balanced. On the suction side, the pump has a valve set with a suction- and pressure valve for each of the cylinders in the bottom section; and, on the drive side, a bistable 3-5 port valve that alternately reciprocates the hydraulic oil flow from the drive unit to the one or the other cylinder pair.

    摘要: A fluid operated pump for use in a wellbore utilizes a removable valve assembly 300 within a longitudinal bore 225 in a housing 200 of the pump. A first fluid path 250 in the housing 200 opening into the bore 225 is provided for supply of pressurized fluid from the bore to an area of the pump below the housing, and a second fluid path 235 in the housing 200 opening into the bore 225 is provided for an exhaust fluid from an area below the housing to the exterior of the housing. In use the valve assembly is lowered to a location in the wellbore proximate the bore 225 in the housing 200, and, after being aligned with and axially inserted into the bore 225 such that ports in an outer valve surface communicate with the first and second fluid paths 250, is sealingly retained in the bore 225 during pumping of fluid by the pump. The valve assembly 300 is then operated within the bore 225 by motive hydraulic fluid supplied to the bore 225 by hydraulic fluid control conduits 345, 350.
