For the production of compressed air in a milking installation working in a vacuum mode, it is provided to drive a piston (7, 13) in a cylinder (9, 14) by a piston (6) and cylinder (5) depression motor by means of a common rod (8). The driving of the depression motor is effected by a pulsating device (2) and compressed air is pumped into a balancing tank (11). |
