Abstract: Apparatus for treatment with pressure waves, comprising: a projectile guided along the movement path, an applicator and a stop, pneumatic means for application of pressure to the projectile for the purpose of movement, wherein the projectile is adapted for striking onto the applicator, which pneumatic means comprises a double valve means for application of pressure to the projectile towards the applicator during a first activation time and in the reverse direction during a second activation time, and a control means adapted, after a partial return movement in a second activation time, to end this second activation time, to start a first activation time and, after only a part of the movement path, to reverse the movement from a return movement into a forward movement.

Abstract: The invention relates to an apparatus for treatment with pressure waves, comprising: a projectile guided along a movement path, an applicator (6) at one end of the movement path, pneumatic means for application of pressure to the projectile (8) for the purpose of movement along the movement path, wherein the projectile (8) is adapted for striking onto the applicator (6) for generating the pressure waves, which pneumatic means comprises a double valve means (1, 2) for application of pressure to the projectile (8) towards the applicator (6) during a first activation time and in the) reverse direction during a second activation time, and a control means (54) adapted to vary the second activation time.
