Hydraulically inflated tractor tyre - has adjustment valve with composite seating, flexible pipe and purge tap

摘要

The tractor tyre valve consists essentially of a bush (3) fixed normally on the cylindrical part of a wheel rim and a composite seating (4). This seating has a tubular projection at an angle and a pipe for a tap (5) and a flexible pipe (5t) for 100% flow. The flexible pipe is fixed on the end of a tap mounted on the connecting pipe and engages radially in this pipe by sliding movement. The arrangement is compatible with the normal methods of tyre fixing to wheels.
