Title
(EN) FORCE BALANCED RECIPROCATING VALVE
(FR) SOUPAPE ALTERNATIVE ÉQUILIBRÉE EN FORCE
Abstract
(EN)
A device for generating pressure pulses includes a valve member disposed in a fluid passageway, the fluid passageway including a restriction, the valve member movable by an actuator relative to the restriction to generate a pressure pulse in a fluid in the fluid passageway based on varying a relative position between the valve member and the restriction and creating a differential pressure across the fluid passageway, the differential pressure applying a first force on the valve member. The device also includes a piston member in hydraulic communication with the differential pressure, the differential pressure applying a second force on the piston member, the piston member having a locomotive mechanical connection to the valve member.

La présente invention concerne un dispositif pour générer des impulsions de pression qui comprend un élément de soupape disposé dans un passage de fluide, le passage de fluide comprenant une restriction, l'élément de soupape étant mobile par un actionneur par rapport à la restriction pour générer une impulsion de pression dans un fluide dans le passage de fluide sur la base de la variation d'une position relative entre l'élément de soupape et la restriction et de la création d'une pression différentielle à travers le passage de fluide, la pression différentielle appliquant une première force sur l'élément de soupape. Le dispositif comprend également un élément de piston en communication hydraulique avec la pression différentielle, la pression différentielle appliquant une seconde force sur l'élément de piston, l'élément de piston ayant un raccord mécanique locomoteur à l'élément de soupape.
