Abstract

Control means for precision control of valves having a through opening (7) which is steeplessly adjustable by means of a valve member (10) which is movable within the valve. According to the invention one end of the valve number (10) is rigidly connected to one end of a rod-like control element (16) of giant magnetostrictive material consisting of an alloy between rare earth metals and iron, cobalt or nickel, particularly an alloy between one or several of terbium, dysprosium, samarium and iron. The opposite end of the control element (16) is attached to a rigid supporting structure and is preferably prestressed in the intended direction of movement, e.g. by means of a spring (19). The control element (16) is surrounded by a solenoid (21) for generating a magnetic field acting upon the control element, said magnetic field being proportional to the supply of current to the coil. The control means further include a control device (37) for control of the supply of current to the solenoid in dependence of selected parameters and in accordance with a predetermined program.
