Abstract: The valve operating device comprises in a housing a valve operating member, which is movable in a compartment in the housing and at its underside has a generally cone-shaped recess, and an operating rod, which is in engagement with the recess with one end and with the other end is in contact with a valve actuating pin of a vehicle air valve, on which the device is mounted. It has a locking sleeve axially movable in the housing and being arranged coaxially with the operating rod and has an internal thread for attachment to the air valve and with an abutment for engagement with a pivotable locking pin of a lock in the housing.
Abstract: A device for operating a valve (1), preferably for a tire valve of a car, where a valve actuating pin (3) is biased to a valve-closing extended position and is to be depressed for opening the valve, has a disc-shaped operating member (6) arranged in a housing (4), which is mounted on the valve. The operating member is provided with a central recess (6') with gradually sloping sides in its surface facing the pin. An operating rod (7) is axially movably arranged in the housing substantially in line with the pin, the rod engaging the recess with one of its ends and the pin with the other.
