ABSTRACT:
A brake valve for a control piston actuatable at will, which shifts a double valve by way of a spring that closes off a flow connection between a working pressure space and a supply reservoir for pressureless brake medium and which during the further movement opens up the inlet between a pressure storage device containing a brake medium under pressure and the working pressure space. A closure member constructed spherically within its sealing area, which together with a stem mounted thereon forms a valve body, is tied to a valve piston by way of this stem in such a manner that the valve member is connected in its longitudinal direction with the valve piston but is radially freely movable with respect thereto to thereby assure centering of the valve member with respect to the valve seat.
