Abstract

The invention is based on a sliding valve ( 10 ) having a sliding sleeve ( 12 ) which is axially displaceable in a control cylinder ( 13 ) and which controls, with at least one control face ( 23 ) on its outer periphery, at least one control opening ( 17, 18 ) in the control cylinder ( 13 ) out. It is proposed that the control face ( 23 ) is radially elastically flexible in the direction of the control cylinder ( 13 ).

Claims (12)

1 - 13 . (canceled)

14 . A sliding valve having a sliding sleeve which is axially displaceable in a control cylinder and which controls, with at least one control face on its outer periphery, at least one control opening in the control cylinder, the control face ( 23 ) being radially elastically flexible in the direction of the control cylinder ( 13 ) and bearing against the control cylinder ( 13 ), wherein the sliding sleeve ( 12 ), in the region of the control face ( 23 ), has at least one longitudinal slot ( 24 ).

15 . The sliding valve as claimed in claim 14 , wherein a plurality of longitudinal slots ( 24 ) are provided, which form between them spring tongues ( 25 ), on which the control faces ( 23 ) are disposed.

16 . The sliding valve as claimed in claim 15 , wherein the spring tongues ( 25 ) are reinforced in the region ( 26 ) of the control faces ( 23 ).

17 . The sliding valve as claimed in claim 14 , wherein the control face ( 23 ) is forced against the control cylinder ( 13 ) by the pressure of a controlled medium.

18 . The sliding valve as claimed in claim 14 , wherein it is realized in cartridge construction.

19 . The sliding valve as claimed in claim 14 , wherein the sliding sleeve ( 12 ) is made of magnetically conductive material and its top part ( 27 ) simultaneously serves as the armature of a magnetic circuit.

20 . The sliding valve as claimed in claim 14 , wherein the sliding sleeve ( 12 ) is guided in the control cylinder ( 13 ) in a torsionally secure manner.

21 . The sliding valve as claimed in claim 14 , wherein the control cylinder ( 13 ) has a conical region ( 28 ) for the threading of the sliding sleeve ( 12 ).

22 . The sliding valve as claimed in claim 14 , wherein it is a fuel injection valve for an internal combustion engine.

23 . The sliding valve as claimed in claim 14 , wherein in the control cylinder ( 13 ) there are provided at least two axially offset control openings ( 17 , 18 ), having adjoining nozzle bores ( 19 , 20 ).

24 . The sliding valve as claimed in claim 23 , wherein at least two nozzle bores ( 19 , 20 ) differ in relation to their position and/or shape.
