Abstract (en)
[origin: EP1072784A2] The control valve is designed so that in the valve body (150) at least one pressure equalizing duct (161) is arranged, which connects the two chambers (168,170) with each other in the valve housing (102). The sides of the two valve elements (154,156) pointing in the two chambers are formed in such a manner so that the pressure forces (Fex1-4) caused by the pressure at the valve elements, which react in the movement direction of the valve body (150), at least are approximately the same value.
