Description

Die Erfindung bezieht sich auf Pulsatoren für Melkmaschinen mit in einem Zylinder hin und her bewegtem Luftverteilungskolben und in den beiden Stirnwänden des Zylinders angeordneten Öffnungen zu je einer Kammer für die vom Luftverteilungskolben gesteuerte, unter verschiedenen Drücken stehende Luft, die den Luftverteilungskolben durch abwechselnd auf eine seiner Stirnwände wirkendenThe invention relates to pulsators for milking machines with in a cylinder reciprocating air distribution piston and in the two end walls of the cylinder arranged openings to one chamber each for the air distribution piston controlled, air under different pressures that alternately pass through the air distribution piston acting on one of its end walls

ίο Überdruck hin und her bewegt.ίο overpressure moved back and forth.

Bei solchen Pulsatoren entstehen leicht Störungen der regelmäßigen Melkarbeit infolge verunreinigter Luft. Die von der Luft mitgeführten Schmutzteilchen setzen sich zwisehen Kolben und Kolbenführung ab und stören so durch vermehrte Reibung den regelmäßigen Gang des Pulsators.With such pulsators, disturbances in the regular milking work easily arise as a result polluted air. The dirt particles carried along by the air settle in between Piston and piston guide and disrupt the regular one through increased friction Pulsator gear.

Dieser für den Betrieb des Pulsators schwerwiegende Nachteil wird durch die Erfin dung beseitigt, indem die Luft .nicht unmittelbar auf die Endflächen des Kolbens einwirkt wie bei den bekannten Bauarten, sondern unter Zwischenschalten elastischer Membranen, die derart angeordnet sind, daß sieThis disadvantage, which is serious for the operation of the pulsator, is made clear by the invention This eliminates the need for air to act directly on the end faces of the piston as with the known types, but with the interposition of elastic membranes, which are arranged so that they

as die Enden des Kolbenzylinders vollständig abschließen. Es ist dann nicht mehr erforderlich, daß der Kolben luftdicht im Zylinder geführt wird, sondern er kann in seiner Führung ein derart großes Spiel haben, daß eine Störung der Kolbenbewegung infolge eindringender Schmutzteilchen völlig ausgeschlossen ist. LTm eine möglichst kräftige Wirkung auf den Kolben zu erhalten, kann die Membran in radialen Erweiterungen der Zylinderenden befestigt sein, so daß der wirksame Durchmesser der Membran größer ist als der Zylinderdurchmesser.as the ends of the piston cylinder completely to lock. It is then no longer necessary for the piston to be airtight in the cylinder is led, but he can have such a big game in his leadership that one Disturbance of the piston movement due to the ingress of dirt particles is completely excluded is. To obtain the strongest possible effect on the piston, the diaphragm can expand in radial directions Be attached cylinder ends so that the effective diameter of the membrane is larger than the cylinder diameter.

Um ferner eine momentane Umsteuerung in den Totpunkten zu sichern, ist es zweckmäßig, die Endwände (Stirnwände) des Zylinders mit Löchern kleineren Durchmessers zu versehen. Die Membranen liegen dann an den Kanten dieser Löcher an, die gewissermaßen den Sitz für die Membran in der Ruhelage bilden. Sofort, wenn die Membran anfängt, sich von dem Sitze abzuheben, dringt Luft zwischen Membran und Sitz ein, so daß die wirksame Fläche der ersteren ganz plötzlich um ein Mehrfaches vergrößert wird. Dadurch erfährt die Bewegung des Kolbens gleich zuIn order to ensure a momentary change of direction in the dead centers, it is useful to the end walls (end walls) of the cylinder with holes of smaller diameter to Mistake. The membranes then rest on the edges of these holes, which are, so to speak, form the seat for the membrane in the rest position. Immediately when the membrane starts stand out from the seat, air penetrates between the membrane and seat, so that the effective area of the former is suddenly enlarged several times. Through this experiences the movement of the piston immediately

Beginn eine große Beschleunigung, so daß jede Gefahr, daß der Kolben in einer Mittellage stehenbleibt, behoben wird.Start a great acceleration, so that there is no risk of the piston in a central position stops, is resolved.

In der Zeichnung ist die Erfindung dargestellt, und zwar istIn the drawing the invention is shown, namely is

In den Abbildungen bezeichnet 1 den Kolben, der sich zwischen den Zylinderwänden 2 taktmäßig hin und her verschiebt. Durch die Zylinderwände sind die Membranen 3 festgeklemmt, die den Zylinderraum gegen die Luft vollständig abdichten. Die radialen Erweiterungen an den Zylinderenden sind mit 4 bezeichnet und die Löcher in den Zylinderwänden 2 mit 5. Deren Kantenflächen 6 bilden den Sitz für die Membranen 3 im Ruhezustände. In the figures, 1 denotes the piston, which moves back and forth between the cylinder walls 2 in a clocked manner. The membranes 3, which completely seal the cylinder space against the air, are clamped in place by the cylinder walls. The radial extensions at the cylinder ends are denoted by 4 and the holes in the cylinder walls 2 by 5. Their edge surfaces 6 form the seat for the membranes 3 in the resting state.
