dc.description.abstract The efficient operation of the mechanical milking operation in the milking rooms, implies the use of pulsers, which allow to change the ratio between the extraction phase and the massage phase and even the working frequency, during operation. These requirements are fully met by the electromagnetic pulsators. The operating organs of these pulsators are actuated by means of electric coils controlled by an electrical circuit. In this way, through the electrical control, various values of the working frequency and different ratios between the extraction and massage time can be achieved. In practice, certain values for the working frequency and certain values for the extraction-massage ratio are accepted at national and European level. Based on these considerations, the author presents in the present paper the results of laboratorytests performed with an electromagnetic type pulsator of his own conception. The tested pulsator allows the production of two different working ratios (extraction time / massage time), namely: 3: 1 and 1.1, at a frequency of 60 pulses / minute. The switching from one working mode to another is controlled by the milk flow coming out of the milk collector. Following the tests performed for various values of the vacuum in the installation, it was observed that the working frequency of the electromagnetic pulsator to be tested remains constant. This parameter is within the normal operating limits of 50 ... 60 +/- 3 pulses / min. Also, the ratios between the extraction time and the massage time are within the usual values en_US
