Abstract

A hydraulic valve includes a sliding control member that delimits at least one constantly adjustable diaphragm. The sliding control member is configured to be moved in the direction of a longitudinal axis. The hydraulic valve further includes a locking device with a locking member that is configured to be moved counter to the force of a first spring transversely relative to the longitudinal axis. The hydraulic valve further includes at least one catch contour in which the locking member is configured to be engaged in such a positive-locking manner that the sliding control member is releasably retained in a catch position that is associated with the respective catch contour. The position of at least one catch contour is constantly adjustable in such a manner that the free cross-sectional surface-area of the at least one diaphragm is constantly adjustable in the associated catch position.
