  "textContent": "The invention relates to a vehicle having an internal combustion engine (22) which comprises a crankcase (14) and a supercharging device (24), with a crankcase ventilation device (10) which comprises at least one inertia-based oil separation device (11) with at least one inertia-based oil separator (12), an oil return (81) returning separated oil to the crankcase (14), and an ejector pump (16) which is driven with compressed air (28) from the supercharging device (24) and which generates a negative pressure in order to drive blow-by gas. [0002] Essential to the invention is that the crankcase ventilation device (10) comprises a pump control valve (18) which regulates and/or controls the flow of compressed air (28) through the ejector pump (16) and which has a closure part (34) which is force-loaded against a valve seat (32) and which is lifted from the valve seat (32) against the force when a pressure difference between a valve inlet (35) and a valve outlet (37) is exceeded or when an inlet-side pressure is exceeded, so that the pump control valve (18) is opened.",
