Description
Aus mehreren zylindrischen Teilen bestehende Hohlkolbenschieber mit schrägliegender Dichtung sind bekannt. Damit bei diesen Schiebern die zwischen den Kolben-Hollow piston valves consisting of several cylindrical parts with an inclined seal are known. So with these slides between the piston
S teilen eingespannte Dichtung nicht nach innen ausweichen kann, ist noch ein besonderer Hohlkolben eingesetzt. Dieser die Konstruktion verteuernde Hohlkolben kann vermieden werden, wenn die Kolbenteile so ausgebildet werden, daß sie am inneren Umfang zur Bildung einer Nut für die Dichtung übereinandergreifen. S dividing the clamped seal cannot move inwards is still a special one Hollow piston used. This hollow piston, which makes the construction more expensive, can be avoided when the piston parts are formed so that they overlap on the inner periphery to form a groove for the seal.
Auf der Zeichnung ist der Schieber in zwei Ausführungsbeispielen dargestellt Abb. 1 ist eine Gesamtansicht eines Schiebers mit schräg verlaufender Dichtung. Abb. 2 ist ein Kolben, bei dem die Dichtung im Zickzack verläuft.In the drawing, the slide is shown in two embodiments, Fig. 1 is an overall view of a slide with an inclined seal. Fig. 2 is a piston, in which the seal runs in a zigzag.
Der Schieber ist zylindrisch und besteht aus zwei am inneren Umfang übereinandergreifenden Teilen 1 und 2, zwischen denen ein aus Dichtungsmasse bestehender Ring 3 schrägliegend oder, wie Abb. 2 zeigt, zickzackförmig gelegt ist. Durch den Schieber führt eine Spindel 4, die im Teil 1 bei 5 dreh-The slide is cylindrical and consists of two overlapping ones on the inner circumference Parts 1 and 2, between which a ring 3 made of sealant sloping or, as Fig. 2 shows, zigzag is laid. A spindle 4, which rotates in part 1 at 5, leads through the slide
bar gelagert und bei 6 in den Teil 2 geschraubt ist, so daß durch Drehen der Spindel'4 der Ring 3 beliebig zusammen- bzw. nachgepreßt werden Lkann, wobei das Mitdrehen des Teiles 1 infolge zweier in Nuten 7 des Gehäuses 8 eingreifenden Führungen 9 verhindert wird. Das Heben und Senken des Schieberkolbens geschieht, während die Spindel 4 durch einen auf ihr mittels Steflschrauben 10 befestigten Ring 11, in welchen die Führungen 12 eingreifen, vpr Umdrehen gesichert ist durch Drehen einer mit einem Hand- oder Zahnrad 13 verkeilten Mutter 14. Im Schieberteil 2 ist eine Bohrung 15 vorgesehen. Diese verhindert eine Druckansammlung im Schieberkolben während des öffnens und Schließens und ein Herauspressen des Dichtungsringes beim Passieren der nicht oder unter geringerem Druck befindlichen Schieberseite. Wird wahrgenommen, daß der Schieber nicht mehr völlig dicht schließt, so werden die Schrauben 10 gelockert und zwischen Mutter 14 und der Spindel 4 in eine vorgesehene Nut der als Keil ausgebildete Schaft · des Schlüssels 16 gesteckt. Wird nun mittels des Rades 13 die Spindel 4 gedreht, so wird durch Anziehen des Kolbenteiles 2 der Dichtungsring 3 zusammengepreßt. bar is mounted and screwed at 6 into the part 2, so that together by rotating the Spindel'4 the ring 3 or arbitrarily be coined L can, wherein the co-rotation of the part 1 as a result of two in the grooves 7 of the housing 8 engaging guides 9 is prevented. The lifting and lowering of the spool is done while the spindle 4 is secured by a ring 11 attached to it by means of screws 10, in which the guides 12 engage, by turning a nut 14 wedged with a handwheel or gear 13 in the slide part 2 a bore 15 is provided. This prevents an accumulation of pressure in the slide piston during opening and closing and prevents the sealing ring from being pressed out when passing the slide side that is not under pressure or is under less pressure. If it is perceived that the slide no longer closes completely tightly, the screws 10 are loosened and inserted between the nut 14 and the spindle 4 in a groove provided in the shaft of the key 16, which is designed as a wedge. If the spindle 4 is now rotated by means of the wheel 13, the sealing ring 3 is compressed by tightening the piston part 2.
