Abstract
A pulsator for milking machines comprises a bolt which travels back and forth in a housing and activates a slide. The slide alternately connects the pulsator's outlets to a source of vacuum and to the atmosphere. A diaphragm accommodated in a chamber at each end of the slide moves the bolt back and forth. An alternator is triggered by the slide as it arrives at one end or the other of its stroke. The alternator connects the chambers back and forth and alternately to the source of vacuum and to the atmosphere. The distance between the slide and at least one of the diaphragms is varied to suppress stagger.
