Abstract
A variable valve actuating system for an internal combustion engine includes an auxiliary pressure accumulator having a one-way type of operation, provided with pawl-like stop means to hold a piston at a position reached due to an increase of pressure within the chamber of the accumulators, against the action of return spring means. When the engine is started, the stop means are deactivated.
