Abstract

1. Hydraulic control for valves (4) of combustion engines having an auxiliary shaft (8) which is driven by the crankshaft and which has a non-circular cross section and, for each valve, a first piston (12) which is actuated by the auxiliary shaft and which slides in a first hydraulic cylinder (13) and a second piston (17) which is pressed against the valve stem (5) and which slides in a second hydraulic cylinder (16) and also a line (15) which connects the first and the second hydraulic cylinder one with the other, characterized in that secured on the auxiliary shafts (8) there is a rolling bearing (9 to 11), against the outer bearing race (11) of which the first piston (12) is pressed and which is fixed in space and is strained only in the elastic region through the deformation which is forced upon it upon rotation of the auxiliary shaft.
