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 the movement path,
• an applicator at one end and a stop at another 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, after a partial return movement in a second activation time, to end this second activation time, to start a first activation time and, by the application of pneumatic pressure to the projectile after only a part of the movement path and before the end with the stop, to reverse the movement of the projectile from a return movement into a forward movement.
