Abstract

Um bei einem Druckmittelzylinder zur Erzeugung einer mechanischen Kraft, mit einem von einem Zylinderboden (4) sowie einem Zylinderdeckel (3) endseitig verschlossenen Zylinderrohr (1), in dem ein mit Druckmittel zumindest einseitig beaufschlagbarer Kolben längs verschiebbar angeordnet ist, von welchem eine den Zylinderdeckel (3) abgedichtet durchdringende Kolbenstange ausgeht, wobei zur Detektion der Kolbenstcllung mindestens ein Sensor (8) längs verschiebbar am Zylinderrohr (1) montiert ist, diesen zuverlässig gegen äußere Einflüsse geschützt am Zylinderrohr auf einfache Weise montierbar/demontierbar bzw. justierbar anzuordnen, wird vorgeschlagen,
dass zur abgedichteten Unterbringung des Sensors (8) im Wandungsbereich des nichtmagnetischen Zylinderrohrs (1) mindestens ein achsparallcler geschlossener Kanal (7) vorgesehen ist, in dem der Sensor (8) über magnetisch betätigbare kraft- oder formschlüssige Befestigungsmittel arretiert ist.

Figure 00000001
In order for a pressure medium cylinder to generate a mechanical force, with a cylinder tube (1) closed at the end by a cylinder base (4) and a cylinder cover (3), in which a piston which can be pressurized with pressure medium at least on one side is arranged to be longitudinally displaceable, one of which is the cylinder cover (3) sealed penetrating piston rod goes out, with at least one sensor (8) mounted longitudinally displaceably on the cylinder tube (1) for the detection of the piston position, to be reliably mounted against the outside influences on the cylinder tube in a simple manner to be assembled / disassembled or adjusted, is proposed .
that at least one axially parallel closed channel (7) is provided for the sealed housing of the sensor (8) in the wall area of the non-magnetic cylinder tube (1), in which the sensor (8) is locked by means of magnetically actuated non-positive or positive locking means.
