Abstract:
1. A module for at least one combustion cylinder of an internal combustion engine having electrohydraulic valve control, comprising: a cylinder head having a plurality of gas exchange valves, at least one gas exchange valve functioning as an inlet valve to control the at least one inlet opening, and at least one other gas exchange valve functioning as an outlet valve to control the at least one outlet opening, at least one high pressure line for supplying fluid under high pressure, at least one recycling line for recycling of fluid, wherein the at least one high pressure line and the at least one recycling line each have at least one coupling opening for hydraulic coupling of the electrohydraulic valve actuators; a plurality of electrohydraulic valve actuators; and an arrangement for detachably fastening the electrohydraulic valve actuators; wherein the number of the electrohydraulic valve actuators corresponds to the number of the gas exchange valves present, and wherein each valve actuator has an actuator housing, the housing having a planar surface with a fluid supply opening, a fluid outflow opening and a leadthrough passage enclosed by a projecting hollow peg for allowing passage of a valve shaft of a gas exchange valve, wherein the fluid supply opening, the fluid outflow opening and the leadthrough passage are arranged in such a way that, at each valve actuator the fluid supply opening rests congruently on the coupling opening of the high pressure line and the fluid outflow opening rests congruently on the coupling opening of the recycling line, and the hollow peg engages the centering opening in a form-locking manner.
