Piston and its use

The piston has a support body (1) connected with a sealing ring (2) on a front side. The sealing ring is made of elastomer, and includes sealing lips (3, 4) that are inwardly or outwardly overlap the support body in a radial direction, where the sealing lips are made of PTFE (6). One of the sealing...

Zusammenfassung:	The piston has a support body (1) connected with a sealing ring (2) on a front side. The sealing ring is made of elastomer, and includes sealing lips (3, 4) that are inwardly or outwardly overlap the support body in a radial direction, where the sealing lips are made of PTFE (6). One of the sealing lips is formed by a PTFE disk (9) that is connected to elastomer substance of the sealing ring in a form-fit manner. The support body is designed in a circular ring shape and made of polymers or metallic substances. Kolben, umfassend einen Tragkörper (1), der zumindest stirnseitig einerseits mit einem Dichtring (2) aus elastomerem Werkstoff verbunden ist, wobei der Dichtring (2) zumindest eine Dichtlippe (3, 4) aufweist, die den Tragkörper (1) in radialer Richtung nach außen oder innen überragt, dadurch gekennzeichnet, dass die Dichtlippe (3, 4) aus PTFE (5) besteht.
