Abstract

A multiway valve for switching the fluid flow of a pressure medium comprising a valve housing (1) with several ports (2a, 2b, 3a, 3b, 4a, 4b) for the pressure medium which are connected with an inner valve hole (5) in which a valve spool (6) for switching the fluid flow between said ports (2a, 2b, 3a, 3b, 4a, 4b) is slidely disposed, and which comprises at least one cap element (7a, 7b) for sealing said valve hole (5) on at least one end side, at least one piston (11) for axially moving said valve spool (6) in a desired switching position which corresponds with a drive chamber (12) formed in the end section of the valve hole (5) to and from which a control fluid is supplied and ejected respectively in order to move said piston (11), wherein said at least one cap element (7a, 7b) comprises at least one through bore (18a, 18b; 25) which in the mounted state of the cap element (7a, 7b) is substantially disposed in a right angle to the axis of the valve hole (6), and wherein said through bore (18a, 18b; 25) corresponds with a second through bore (18) in the valve housing and also with a bore (19; 22) in a tight-fitting support element in order to fix the cap element (7a, 7b) to the valve housing (1) and to fix the valve housing (1) to the support element by the same fixing means.
