ABSTRACT:
A device for the generation of pressure pulses, includes a cylinder (3), a piston that is displaceably arranged in the cylinder (3), a pressure fluid circuit with an inlet (6) into and an outlet (7) out of the cylinder (3) on one side of the piston (4), a shaft (18) connected to the piston (4), and a liquid-filled chamber (17). The shaft (18) is arranged to be displaced through said chamber (17) in connection to a displacement of the piston (4) in the cylinder (3). The device includes at least one valve member (22, 24, 29, 32) for an occasional interruption of a flow of liquid out of the chamber (17).
