Electrohydraulic device for locking adjusting movements in friction brakes and lifting devices has a cylinder, a piston linked to a piston-rod, a cylinder base and two cylinder covers

摘要

#CMT# #/CMT# A first cylinder cover (3) links firmly to a cylinder (1). A second cylinder cover (4) is placed in the cylinder so as to float. The cylinder forms an electric lifting magnet with an armature (5) in the cylinder between a piston (2) and the second cylinder along with a piston and a coil (7) fitted coaxially around the cylinder and an iron rear-end. The armature activates an on-/off-valve in the piston, consisting of a valve seating (18), a nozzle bore (12), a valve seal (11) and a valve lifter (10). #CMT#USE : #/CMT# Electrohydraulic device for locking and releasing adjusting movements in friction brakes and lifting devices. #CMT#ADVANTAGE : #/CMT# Spaces between the piston and the cylinder covers are filled with hydraulic fluid. A dynamic effect occurs caused by the armature on the valve lifter for the on-/off-valve in the piston if an electric current flows through the coil #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a vertical cross-sectional diagram of a ferromagnetic cylinder. 1 : Cylinder 2 : Piston 3 : First cylinder cover 4 : Second cylinder cover 5 : Armature 6 : Cylinder base 7 : Coil 10 : Valve lifter 11 : Valve seal 12 : Nozzle bore 13 : Piston-rod 18 : Valve seating.
