The invention provides a pneumatically operated circuit for automatically shutting off the flow of high pressure air being introduced into an object such as a tire, when the pressure in the object reaches a preselected maximum pressure significantly below the high pressure supply. The air is introduced automatically in timed, high pressure bursts and between the time bursts a safety mechanism gauges the pressure that has built up in the object and interrupts further timed bursts when the latter pressure exceeds the preselected maximum.
