Title (EN) PRESSURE PULSE GENERATOR
(FR) GENERATEUR D'IMPULSIONS DE PRESSION
Abstract: front page image
(EN)A pressure pulse generator comprising a circuit (12) filled with a pressure fluid, and at least one communication channel (15) that is connected to the circuit and via which the pressure fluid can flow into and out of the circuit. The pressure pulse generator comprises a first pair (8, 9) and a second pair (10, 11) of electrically controlled valves that are connected in series, and the first pair of valves (8, 9) is arranged in said circuit (12) upstream the at least one communication channel (15), and the second pair of valves (10, 11) is arranged in said circuit (12) downstream the at least one communication channel (15).
(FR)L'invention concerne un générateur d'impulsions de pression comprenant un circuit (12) rempli d'un fluide de pression, et au moins une voie de communication (15) qui est reliée au circuit et par l'intermédiaire de laquelle le fluide de pression peut s'écouler à l'intérieur et à l'extérieur du circuit. Le générateur d'impulsions de pression comprend des première (8, 9) et seconde (10, 11) paires de vannes commandées électriquement qui sont reliées en série, la première paire de vannes (8, 9) étant disposée dans ledit circuit (12), en amont de la voie de communication (15), et la seconde paire de vannes (10, 11) étant disposée dans ledit circuit (12), en aval de la voie de communication (15).
