Pressure Wave Apparatus With Double Valve Means

An apparatus for treatment of the human or animal body with mechanical pressure waves, the apparatus comprising:

• a projectile guided in the apparatus along a movement path,
• an applicator at one end of the movement path,
• pneumatic means for application of pneumatic pressure to the projectile for the purpose of movement along the movement path,
• wherein the projectile is adapted for striking onto the applicator for generating the mechanical pressure waves,
• which pneumatic means has a double valve means for application of pneumatic pressure to the projectile in the direction towards the applicator during a first activation time and for application of pneumatic pressure to the projectile in the reverse direction during a second activation time and a control means for controlling the double valve means,
• wherein the apparatus is adapted to maintain a separation time between the first activation time and the second activation time or vice versa and to control an impact speed of the projectile upon impact onto the applicator by means of the separation time.
