Electrically actuatable length adjuster, has valve unit comprising throttle unit whose tube end is connected to front-side contact surface of cylindrical valve actuator, which is movably arranged in magnet housing

摘要

The adjuster has a cylindrical housing (1) i.e. pipe housing, filled with compressible or incompressible fluid e.g. compressed gas. A valve unit (19) is arranged within the housing. A magnetic coil (33) of an electromagnetic valve operating unit (30) is arranged in a ring-cylindrical multi-part magnet housing (31). Permanent magnets (42) are arranged in a base (4). The valve unit comprises a throttle unit with a tube end that is connected to a front-side contact surface (29) of a cylindrical valve actuator (25), which is movably arranged in the magnet housing.
