摘要

A periodic milking apparatus of constant pulsation and adjustable depression, constituted essentially by a cylinder with a moving internal piston which is a single effect impelling suction pump communicating the reciprocating movement to the piston by the connecting rod-crank system; the milk collection tank and the suction device adapted to the nipple, elements linked by the elastic milk conduction pipes from the suction device to the tank, the suction and air compression pipe from the suction device housing to the central distributor from the metal lid of the tank, the connecting air pipe from the central distributor with the piston chamber, and the connection of the milk collection tank with the control manometer.
