Abstract

In a pulsator device of the slide valve type for milking cows with each of the valves being operated by a pair of diaphragms driven by a vacuum applied from outside, the initial adjustment or gauging, after a certain period of working, is no longer present and it is not possible to correct the gauging at the place of working. Furthermore, such pulsators cannot be used for milking ovine animals if they have not been suitably gauged at the works originally. In order to prevent the device from getting out of tune and therefore changing the rate of operating and in order to make it possible to renew the gauging at the place of working and to alter it if it is desired to use the apparatus for ovines also, instead of expelling the air which happens to be present on the other side of the diaphragms, said air is made to move in a closed circuit through a pipe (31) which links the two chambers concerned (29 and 30) with the opening of the passage which is adjustable from outside.
