PCT No. PCT/EP81/00071 Sec. 371 Date Feb. 16, 1982 Sec. 102(e) Date Feb. 16, 1982 PCT Filed Jun. 11, 1981 PCT Pub. No. WO81/03681 PCT Pub. Date Dec. 24, 1981.A boost control device for an internal combustion engine with an exhaust gas turbocharger includes a bypass valve in a bypass line parallel to an exhaust gas turbine of the exhaust gas turbocharger, a motor operator for the bypass valve which can be loaded in the opening and closing directions by charge air, a control valve which feeds charge air to the motor operator as a function of boost pressure, where the control valve feeds charge air to the motor operator of the bypass valve in the closing direction up to a pre-established boost pressure and this feed can be vented to the environment by the control valve, and a pressure control valve which can be loaded by the charge air in the opening direction. The pressure control valve is loaded in the closing direction by a barometric plug which is exposed to ambient pressure and is prestressed as a function of at least one of the ambient temperature and the charge air temperature.
