    • The invention relates to a vacuum generating device (1) and to a method suitable for the operation thereof. An ejector unit (27) is connected with an inlet (29) thereof to an air supply channel (32) that can be selectively closed or opened by an electronic control unit (14) in order to selectively turn off or turn on the ejector unit (27). When the ejector device (27) is turned on, a negative pressure is generated in a suction channel (35). The ejector unit (27) is operated such that the negative pressure fluctuates between an upper switching value and a lower switching value. By comparison to a reference value, the operating period of the ejector unit (27) is determined in order to generate a diagnosis signal that allows a conclusion of the leak that is present.
