ABSTRACT:
A rotary feedthrough for a device to inflate and deflate a tire on a tractor wheel has a housing (13) with an inner member (28) arranged at a radial distance within the housing. The radial gap is bridged by two radially distanced closing elements (18, 22). The inner member (28) is supported in the closing elements (18, 22). Two seal combinations, including respectively, a first sealing ring (35) and a second sealing ring (41), are arranged mirror-invertedly to the inner member (28). The first sealing rings (35), with a first sealing face (36), abut a counter sealing face (21) or (25) of the closing elements (18, 22), respectively. Each first sealing ring (35) can be moved axially along the longitudinal axis Y. Each first sealing ring (36) is fixed rotationally to the inner member (28). Each first sealing ring (35) is acted upon by a second sealing ring (41). An annular edge of a sealing portion (43) abuts the second sealing face (36) of the first sealing ring (35) and presses the same against the counter sealing face (21) or (25), respectively, under the pressure present in the chamber K.
