Multi-way valve for control of fluid flow has piston moving longitudinally in cylinder with sealing rings to open and close ports defined by cutouts in piston
The valve (1) has a casing (2) with a longitudinal blind bore with grooves and side pockets (3). Sealing rings (12) are fixed at intervals in the bore and engage the cylindrical surface of the piston (4). There are cutouts (16) in the piston which can allow fluid to flow past the sealing rings when...

| description | The valve (1) has a casing (2) with a longitudinal blind bore with grooves and side pockets (3). Sealing rings (12) are fixed at intervals in the bore and engage the cylindrical surface of the piston (4). There are cutouts (16) in the piston which can allow fluid to flow past the sealing rings when the piston is in the right position. The piston is tubular, with thick walls (15) on either side of the cutouts. A large number of valve chambers (8) are formed in the walls of the casing, and there is a plug (43) in the end of the bore.
Es wird ein Mehrwegeventil (1) vorgeschlagen, das einen Ventilschieber (4) aufweist, der mit seinem vorderen Ende in eine Abströmkammer (8d) hineinragt und der rückseitig mit einem Steuerkolben (18) zur Variation der Schaltstellung ausgestattet ist. Um ungewollte Schaltvorgänge zu vermeiden, ist ein relativ zum Ventilschieber (4) verschiebbarer Abstützkolben (28) vorgesehen, der mit dem Ventilschieber (4) einen Beaufschlagungsraum (35) begrenzt. Wird der Beaufschlagungsraum (35) mit Fluid beaufschlagt, stützt sich der Abstützkolben (28) am Gehäuse ab und der Ventilschieber (4) wird in der gewünschten Schaltstellung gehalten. |
