Device for variably adjusting control time of inlet gas shuttle valve and outlet gas shuttle valve of internal-combustion engine, has separation element with two porous sections that limit respective chamber in shifting direction of element

摘要

The device has a pressure chamber divided by a separation element (18) into two pressure chambers working against each other. A phase position of a drift element is variably adjustable relative to a drive component by pressurizing the chambers, when simultaneously emptying the other chamber. The separation element has two porous sections (36, 37) made of sintered material, and a pressurized medium impermeable region (35) that is arranged between the porous sections, where the sections limit the respective chamber in a shifting direction of the separation element.
