The four 2/2 distributing valves (41, 42, 45, 46) of the valve module (2) are interconnected in a full bridge arrangement. According to the invention, an additional module (6, 7), which is arranged on the connection surface of the channel body, is connected so it communicates with one or both working channels (21, 22) and is designed to control a fluid flow and/or for determining a parameter of the fluid flow from or to the working channel (21, 22).

Abstract: The invention relates to a vacuum generating device (1) and to a method suitable for the operation thereof. An ejector device (27) is connected with an inlet (29) thereof to an air supply conduit (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 device (27). When the ejector device (27) is turned on, a vacuum is generated in a suction channel (35). The ejector device (27) is operated such that the vacuum fluctuates between an upper switching value and a lower switching value. By comparison to a reference time value, the operating period of the ejector device (27) is determined in order to generate a diagnosis signal that allows a conclusion of the leak that is present.
