Multiway valve with a removable exhaust wall

摘要

A multiway valve for controlling the flow of a pressure medium from at least one delivery port to at least one exhaust port or supply port includes a valve housing with a substantially cylindrical axial bore with a plurality of annular steps forming inner chambers for connecting the ports. The multiway valve further includes a spool arrangement for switching the flow of the pressure medium. The spool arrangement includes two valve spools arranged coaxially and in tandem in the axial bore. The two valve spools are independently axially slidable within the axial bore. Each valve spool is associated with at least one driving piston for axially shifting the valve spool in response to a control pressure. A common exhaust chamber is arranged next to the inner ends of the valve spools in the center of the axial bore to provide a connection to the at least one exhaust port. An exhaust wall is arranged between the inner ends of the valve spools in the exhaust chamber for dividing the chamber in two parts and directing a main exhaust stream from the each valve spool to the at least one exhaust port.
