A multiway valve has a valve spool space in its valve housing in order to accommodate two valve spools arranged in tandem. Since such two valve spools are able to be operated independently of each other, different valve functions may be performed by the valve.

A multiway valve comprising: a valve housing having a valve spool space therein, the housing being longitudinally divided into at least two parts along a parting plane forming a joint portion adjacent to the spool space; a valve spool arrangement, the spool space being adapted to receive the valve spool arrangement, the valve spool arrangement including two valve spools arranged coaxially in tandem and which are independently axially slideable within the spool space, each valve spool having a piston disposed on a terminal part thereof, each piston being axially slidable within a piston space, each piston space being disposed at a terminal end of the valve spool space, the piston providing for axially shifting of its associated valve spool upon engagement with a control pressure thereby affecting a supply of an actuating fluid; and a pair of guide sleeves, each sleeve lining one of the piston spaces and being radially disposed therein.
