Abstract

The invention relates to a 5/2-way valve in which the two control pistons with their inner end faces define the housing chambers which are provided with the connections for the removal of the pressure medium and are capable of limited free movement in an axial direction relative to the piston rod. Such a valve is distinguished by a particularly small size and a simple construction.
