Patent CA-2474410-C (CA)
Inventor: BUTLER BRYAN VIRGE
IPC: F04B49/22
Filed: 2004-07-15
Granted: 2009-05-05
Abstract: The present invention provides a hydraulically driven multiphase pump system and methods for pumping a fluidstream from the surface of a well. The hydraulically driven multiphase pump system consists of two vertically disposed plungers. The plungers are hydraulically controlled and actuated to work in alternate directions during a cycle using a closed loop hydraulic system. Each cycle is automatically re-indexed to assure volumetric balance in the circuits. An indexing circuit ensures that each plunger reaches its full extended position prior to the other plunger reaching its preset retracted position. A power saving circuit is used to transfer energy from the extending plunger to the retracting plunger. A trim circuit is used to ensure a proper fluid level in the indexing circuit and the power saving circuit. Additionally, a rapid reversal circuit may be employed to increase the rate of the two vertically disposed plungers.

Abstract: A compression spring comprises a casing in which a piston is arranged for displacement, the piston being mounted on a piston rod. In the casing provision is made for two sectional casing chambers which are filled with pressure fluid, at least one of which being defined by the piston. A first operating valve, in an open position, connects the sectional casing chambers to each other and, in a shut-off position, blocks the compression spring. An additional throttle element ensures that an actuation and overflow assembly between the sectional casing chambers is completely open only when the throttle element, with the valve pin tripped, is simultaneously moved by corresponding actuation into a position of release. Without any such actuation of the throttle element, there will be only throttled flow between the sectional casing chambers. Any inadvertent extension of the piston rod is thus precluded. This is an especially convenient and intuitive way of backrest adjustment in a seat.
