Milking system with variable pressure source.

A MILKING SYSTEM (10) THAT MAKES USE OF A VARIABLE PRESSURE SOURCE (82) AND THAT VARIATIONS THE PRESSURE SUPPLIED TO THE PULSATION CHAMBER (32) ALONG A CONTROLLABLE VARIABLE PRESSURE CURVE WITH A SELECTABLE WAVE FORM . THE PULSATION CYCLES ARE SHORTENED BY SHORTENING THE TRANSITION TIME BETWEEN THE LEVELS OF PRESSURE, WHICH OBTAINS ACTIVE AND NON-ACTIVE PORTIONS OF THE PULSATION CYCLE. THE PULSATION CHAMBER (32) IS SEQUENCED THROUGH DIFFERENT PRESSURE CHANGE SPEEDS, ALL DURING THE TRANSITION. THE TRANSITIONAL MOMENTS OF PRESSURE DURING THE PRESSURE CYCLES ARE CHANGED AT THE BEGINNING, IN THE MIDDLE AND AT THE END OF A MILKING INTERVAL TO OBTAIN A FASTER SPEED OF THE SUCTION CUP OPENING MOVEMENT AT THE BEGINNING OF THE MILKING INTERVAL AND THEREFORE GETTING A DEEPER PENETRATION OF THE TUCKET AND A INTERMEDIATE MOVEMENT SPEED FROM THE SUCTION CUP TO HALF THE MILKING INTERVAL AND A LOWER SPEED OF THE SUCTION CUP OPENING MOVEMENT AT THE END OF THE MILKING INTERVAL TO LIMIT THE LOSS OF ADHESION BETWEEN A TETINA THAT IS NOT COMPLETELY FULL AND INSIDE THE SUCTION CUP.
