Abstract
A tubular valve for adjusting the compression ratio of a variable compression ratio engine includes a straight tube capable of longitudinal translational movement in a valve casing including a low-pressure chamber, the straight tube including a first end opening into the low-pressure chamber and a second end opening into a high-pressure chamber, the second end adapted to contact with at least one shut-off surface secured to the valve casing to seal the second end, the straight tube contacting the shut-off surface by at least one nonreturn and shut-off spring; sealing element for sealing between the external surface of the straight tube and the valve casing isolating the high-pressure chamber from the low-pressure chamber, the sealing element including a nonreturn tube inside which the straight tube is held; and an electric actuator for applying to the straight tube a force opposing that of the spring.
