Mounted in the housing (2) of the valve (1) in the milking device described is an air channel (5) and a bypass channel (6) in which a shut-off element (7) is fitted. The connection tube (3) on one side of the valve (1) is connected to a pulsator and the connection tube (4) on the other side of the valve (1) is connected to the pulse chamber of a teat cup by means of a line (8) which is divided in the vicinity of the valve (1). The shut- off element (7) has an obturator (9) which is biased by a compression spring (10) in the valve-opening direction. During the pulse-chamber evacuation phase, the air channel (5) and the bypass channel (6) are available for the air flow. During the air-entry phase, the bypass channel (6) is closed off by the shut-off element (7) so that only the air channel (5) is available for the air-flow. During the evacuation phase, a significantly greater cross-sectional area is thus available for the air flow than during the air-entry phase. This ensures a rapid reduction in pressure during the evacuation phase and a slower increase in pressure during the air-entry phase in the pulse chamber of the teat cup, thus ensuring that the teats are massaged more delicately.
Un conduit d'air (5) et un canal de dérivation (6) auquel est associé un élément d'obturation (7) sont prévus dans le corps (2) de la soupape (1). Une conduite pulsée (8) divisée dans la zone de la soupape (1) permet d'assurer la jonction entre le raccord (3) de la soupape (1) et un pulsateur, et le raccord (4) et la chambre pulsée d'un récipient trayeur. L'élément d'obturation (7) comporte un corps de soupape (9) sollicité par un ressort de pression (10) dans le sens d'ouverture. En phase d'évacuation de la chambre pulsée, les sections du conduit d'air (5) et du canal de dérivation (6) permettent à l'air de s'écouler. En phase de ventilation, le canal de dérivation (6) est fermé par l'élément d'obturation (7), de manière à ce que le conduit d'air (5) n'assure que l'écoulement de l'air. En phase d'évacuation, la section transversale à disposition pour l'écoulement de l'air est par conséquent sensiblement plus grande qu'en phase de ventilation, ce qui permet une suppression rapide de la pression en phase d'évacuation et une remontée plus lente de la pression en phase de ventilation dans la chambre pulsée du récipient trayeur. L'action massante exercée sur les trayons ne les altère de ce fait en aucun cas.
