Abstract
An electrohydraulic control module is provided for making available a compressed fluid, especially compressed oil for actuators, which are used for actuating control units, for example, for switching gas-exchange valves of an internal combustion engine on and off, with a control housing, which is attached to a connection part of the internal combustion engine and which has electrical switching valves that are connected to an oil supply line and to control oil lines leading to the actuators. The production and assembly expense of the electrohydraulic control modules is reduced in that an intermediate housing (), which is injection molded from plastic and which has at least the oil supply line and the control oil lines (), is clamped between the connection part () and the control housing ().
