Pilot-control stage for a proportionally controlled high-pressure hydraulic valve

摘要: Example pilot-control stage for a proportionally controlled high-pressure hydraulic valves are disclosed. An example includes housing of valve, the comprising piston chamber, guide disposed within chamber to move in an axial direction along having aperture and tappet, compensating extending into aperture, where moves define bore fluidly coupling valve electromagnetic coil at least partially surrounding seals between control piston, tappet housing, acts as armature current applied isolate from areas.
