Abstract:
There is disclosed a friction detent apparatus for use in hydraulic spool valve assemblies. In an embodiment, the apparatus comprises: a detent plunger; a friction tube adapted to fit over at least one recessed section of the detent plunger; and an adjustable friction collar adapted to slidingly engage an outer surface of the friction tube and to provide frictional resistance to movement of the detent plunger in an axial direction. The linear frictional resistance provided by the friction detent apparatus provides smoother operation of a hand lever mechanically connected to the detent plunger via a main spool of a hydraulic spool valve within the hydraulic spool valve assembly, and the amount of linear frictional resistance can be adjusted independently from any detent breakout force.
