摘要

An attachment (23) enclosed by a cover (21)has an adjusting lever (11) protruding from the valve housing fitting into it. The adjusting lever is fixed in its inserted position by a radially accessible fastening (231) beneath the cover. A covering sleeve (24) attached to the cover covers the fastening. The covering sleeve is axially movably fixed to the cover. In a first position a gap (25) is formed between the cover and covering sleeve, through which at least one tool (3) fits for operating the fastening, while in the second position the covering sleeve rests on the cover. Axially protruding sprung tongues (241) near one end side of the covering sleeve fit into one or more annular grooves (212,213) on the inside of the cover.
