Abstract

I.C. engine is liquid-cooled and has valves which can be replaced independently from the cylinder head. The cooling spaces can be connected with the coolant circuit via coolant feed-and take-off lines which can be shut off. Specifically, there is a cut-off slide (29,42) outside the valve cage (6) in the machine housing (2) which is acted upon by a servo mechanism (35). In its open position, the slide is supported on a machine part (12) which can be removed with the valve cage (6). In its cut-off position, the slide is supported on a stroke limiting stop (36). The servo mechanism can be a spring (35) which acts in the cut-off direction.
