<p>The invention concerns a rotary joint for transmission of operating impulses to a rotary machine. According to the invention the joint is designed having a non rotary housing (10) surrounding a rotating shaft (11) and sealed by a mechanical seal (25). For transmitting the monitoring impulses hydraulic fluid is used which is transported between the housing (10) and the shaft (11) via a distribution socket (14) so arranged, that a number of column seals (15) are formed between the shaft and the socket (14). The device is supported by two prestressed, reversed roller bearings (26, 27).</p> |
